     BRIEF SUMMARY OF THE INVENTION 
     According to a first aspect, a stretching device for stretching an item of packaging, in particular a pouch, for an object, in particular a pharmaceutical or cosmetic object, is therefore proposed, wherein the item of packaging has a projecting packaging portion. The stretching device has a transportation installation for transporting the object in a transportation direction, a holding installation for holding the projecting packaging portion, and a motion installation for moving the object. The holding installation has at least two rollers which are disposed so as to be perpendicular to the transportation direction and which are configured for holding the projecting packaging portion therebetween. The motion installation and/or the holding installation are/is configured so as to be movable parallel with the transportation direction in order for the object and the holding installation to be moved away from one another. 
     According to a second aspect, a method for stretching an item of packaging, in particular a pouch, for an object, in particular a pharmaceutical or cosmetic object, is proposed, wherein the item of packaging has a projecting packaging portion, wherein the object is transported in a transportation direction on a transportation installation. The method herein comprises the following method steps:
         holding the projecting packaging portion by a holding installation, wherein the holding installation has at least two rollers which are disposed so as to be perpendicular to the transportation direction, wherein the projecting packaging portion is held between the at least two rollers; and   moving the object and/or the holding installation parallel with the transportation direction in order for the object and the holding installation to be moved away from one another.       

     The object is transported on the transportation installation. The transportation direction of the object corresponds to the moving direction of the object on the transportation installation. The terms “upstream” and “downstream” herein are to be understood in relation to the transportation direction. 
     The terms “longitudinal side” and “end side” are likewise to be understood in relation to the transportation direction. A “longitudinal side” herein is disposed so as to be substantially parallel with the transportation direction. By contrast, an end side is disposed so as to be substantially perpendicular to the transportation direction. 
     The spatial arrangement of elements hereunder is stated relative to the transportation installation and to the item of packaging that is transported on the transportation installation, or relative to the object that is transported on the transportation installation, respectively. The item of packaging has a longitudinal side that faces the transportation installation, and a longitudinal side that faces away from the transportation installation. The transportation installation likewise has a side that faces the item of packaging/the object, and a side that faces away from the item of packaging/the object. Accordingly, elements can be disposed on that side of the transportation installation that faces the item of packaging/the object, or on that side that faces away from the item of packaging/the object. 
     On account of the projecting packaging portion by means of a holding installation being held on an end side of the item of packaging, and the item of packaging being moved in a direction that points away from the holding installation, the item of packaging is stretched at the end side. Since the rollers are disposed so as to be perpendicular to the transportation direction, said rollers acquire a part of the packaging portion that is disposed on an end side of the item of packaging. On account thereof, the item of packaging is stretched parallel with the transportation direction and at the end side of the item of packaging. 
     On account of the stretching parallel with the transportation direction, significantly less space is required laterally to the transportation installation, since the stretching procedure is performed above the transportation installation. Only individual components of the motion installation or of the holding installation can be disposed laterally to the transportation installation. However, a majority of said components is preferably disposed on that side of the transportation installation that faces away from the object or faces the latter. 
     On account of the stretching parallel with the transportation direction, the following devices of an unpacking system such as, for example, a severing device for severing the stretched packaging portion and a retrieving device for retrieving the object from the item of packaging can furthermore likewise be disposed in the transportation direction without any additional repositioning of the packed object being required. 
     According to a third aspect, a folding-out device for folding outwards a packaging portion of an item of packaging, in particular a pouch, for an object, in particular a pharmaceutical or cosmetic object, is proposed. The folding-out device has a transportation installation for transporting the object in a transportation direction, a lifting installation for raising the object, a holding installation for holding a region of the item of packaging that is adjacent to the packaging portion, and a holding-installation drive installation for moving the holding installation in a direction that points away from the packaging portion. 
     According to a fourth aspect, a method for folding outwards a packaging portion of an item of packaging, in particular a pouch, for an object, in particular a pharmaceutical or cosmetic object, is proposed, wherein the object on a transportation installation is transported in a transportation direction. The method herein comprises the following method steps:
         raising the object by a lifting installation;   holding a region of the item of packaging that is adjacent to the packaging portion by a holding installation; and   moving the holding installation in a direction that points away from the packaging portion.       

     The packaging portion on one side is connected to the item of packaging at a connection point and, proceeding from the connection point, extends along the item of packaging up to a region on the longitudinal side of the item of packaging that faces or faces away from the transportation installation. The region that is adjacent to the packaging portion is to be understood as such a region of the item of packaging that is contiguous to the connection point between the packaging portion and the item of packaging, and extends away from the packaging portion. 
     For example, the packaging portion initially can be partially disposed between the longitudinal side that faces the transportation installation and that side of the transportation installation that faces the item of packaging, and on account thereof is folded inwards between the transportation installation and the item of packaging. The connection point herein can be disposed on an end side of the item of packaging. The packaging portion in this instance can extend from the connection point towards the transportation installation up to between the transportation installation and the longitudinal side of the item of packaging that faces the transportation installation. In this case, one region of the end side that is on that side of the connection point that points away from the transportation installation, and one region of the longitudinal side that faces away from the transportation installation correspond to a region of the item of packaging that is adjacent to the packaging portion. Furthermore, the connection point can also be disposed on the edge between an end side and that longitudinal side that faces the transportation installation. In this case, the end side corresponds to a region that is adjacent to the packaging portion. Furthermore, the connection point can also be disposed on the edge between an end side and the longitudinal side that faces away from the transportation installation. In this case, the longitudinal side that faces away from the transportation installation corresponds to a region that is adjacent to the packaging portion. Furthermore, the connection point can also be disposed on the longitudinal side that faces away from the transportation installation, or on the longitudinal side that faces the transportation installation. The respective adjacent region in this instance corresponds to the region of the item of packaging that extends from the connection point away from the packaging portion. 
     If the region that is adjacent to the packaging portion is now moved or drawn away from the packaging portion, in particular away from the connection point between the packaging portion and the item of packaging, a tensile force is exerted by way of the connection point on the packaging portion. On account of said tensile force, the packaging portion is drawn out of the folded-in position thereof between the longitudinal side of the item of packaging that faces the transportation installation and the transportation installation and is thus folded outwards. The adjacent region herein can be drawn so far until the packaging portion has been completely folded outwards and is disposed in a desired position. The packaging portion in the desired position extends preferably parallel with the transportation installation, in particular parallel with the transportation direction, and away from the item of packaging, in particular away from the connection point. 
     In one alternative embodiment the packaging portion initially is partially folded inwards onto the longitudinal side of the item of packaging that faces away from the transportation installation. The connection point herein can be disposed on an end side of the item of packaging. The packaging portion in this instance can extend from the connection point away from the transportation installation up to the longitudinal side of the item of packaging that faces away from the transportation installation. Accordingly, the adjacent region is disposed on that side of the connection point that faces the transportation installation. The folded-in packaging portion can thus likewise be folded outwards by drawing the adjacent region away from the connection point. 
     On account of the packaging portion being folded outwards, subsequent steps in the unpacking method, or the handling of the item of packaging on downstream devices for stretching and/or severing the packaging portion, respectively, are significantly simplified. For example, a stretching device can more readily acquire and stretch the packaging portion. 
     According to a fifth aspect, a folding-out device for folding outwards a packaging portion of an item of packaging, in particular a pouch, for an object, in particular a pharmaceutical or cosmetic object, is proposed. The folding-out device has a transportation installation for transporting the object in a transportation direction, a lifting installation for raising the object, and a detent installation. The detent installation has at least one roller which is disposed so as to be perpendicular to the transportation direction and which is disposed on that side of the item of packaging that faces away from or faces the transportation installation and forms a detent for the folded-in packaging portion. The lifting installation and/or the detent installation are parallel configured so as to be movable/is with the transportation direction in order for the object and the detent installation to be moved relative to one another. 
     According to a sixth aspect, a method for folding outwards a packaging portion of an item of packaging, in particular a pouch, for an object, in particular a pharmaceutical or cosmetic object, is proposed, wherein the object on a transportation installation is transported in a transportation direction. The method herein comprises the following method steps:
         raising the object by a lifting installation;   first moving of the lifting installation relative to a detent installation parallel with the transportation direction in such a manner that the item of packaging at least in portions is disposed on the detent installation;   bringing to bear a roller of the detent installation on a longitudinal side of the item of packaging in order for a detent for the packaging portion to be formed; and   second moving of the lifting installation relative to the detent installation parallel with the transportation direction in such a manner that the folded-in packaging portion is folded outwards.       

     On account of the packaging portion being folded outwards, subsequent steps in the unpacking method, or the handling of the item of packaging on downstream devices for stretching and/or severing the packaging portion, respectively, are significantly simplified. For example, a stretching device can more readily acquire and stretch the packaging portion. 
     According to a seventh aspect, an unpacking system having a stretching device according to the first aspect or one of the design embodiments thereof, and having a folding-out device according to the third or fifth aspect or one of the design embodiments thereof, is proposed. 
     According to an eighth aspect, a method for unpacking an object, in particular a pharmaceutical or cosmetic object, from an item of packaging, in particular a pouch, is proposed, wherein the object on a transportation installation is transported in a transportation direction, wherein a packaging portion of the item of packaging initially is folded inwards between the transportation installation and the item of packaging. The method here in comprises the following method steps:
         folding outwards the packaging portion by means of the method according to the fourth or the sixth aspect or one of the design embodiments thereof;   stretching the projecting packaging portion by means of the method according to the second aspect or one of the design embodiments thereof;   completely severing the projecting packaging portion; and   retrieving the object from the item of packaging.       

     In the case of the unpacking system described, and in the case of the method for unpacking described, a packaging portion which initially is folded inwards is folded outwards and subsequently stretched. The individual components of the stretching device and of the folding-out device herein are disposed in a compact and space-saving manner. On account of the packaging portion being stretched parallel with the transportation direction, a compact arrangement of the subsequent handling devices such as, for example, a severing device and/or a retrieving installation is enabled. 
     According to a ninth aspect, an unpacking system for unpacking an item of packaging, in particular a pouch, for an object, in particular a pharmaceutical or cosmetic object, is proposed, wherein the item of packaging has a projecting packaging portion which is disposed on an upstream end side of the item of packaging. The unpacking system has a transportation installation for transporting the object in a transportation direction, and a holding installation for holding the projecting packaging portion. The holding installation has at least two rollers which are disposed so as to be perpendicular to the transportation direction and which are configured for folding outwards and/or stretching the projecting packaging portion. 
     According to a tenth aspect, a method for unpacking an object, in particular a pharmaceutical or cosmetic object, from an item of packaging ( 12 ), in particular a pouch, wherein the object ( 14 ) on a transportation installation ( 18 ) is transported in a transportation direction ( 20 ), wherein the item of packaging ( 12 ) has a folded-in packaging portion ( 16 ) which is disposed on an upstream end side ( 28 ″) of the item of packaging ( 12 ) and extends on a longitudinal side ( 30 ′,  30 ′″) that faces of faces away from the transportation installation ( 18 ). The method ( 200 ) herein comprises the following method steps:
         bringing to bear two rollers which are disposed so as to be perpendicular to the transportation direction and so as to be mutually parallel on a longitudinal side of the item of packaging that faces the transportation installation, and on a longitudinal side of the item of packaging that faces away from the transportation installation, in order for a detent for the projecting packaging portion to be formed in such a manner that the projecting packaging portion is folded outwards;   holding the projecting packaging portion between the two rollers in order for the projecting packaging portion to be stretched;   severing the projecting packaging portion; and   retrieving the object from the item of packaging.       

     In the case of such an unpacking system and method for unpacking, no lifting installation or motion installation is required. Instead, the packed objects are moved further along on the transportation installation, in particular at a consistent speed. This unpacking system and the method for unpacking thus represent a particularly space-saving solution, since significantly fewer components are required. 
     In the case of this method it is however mandatory that the projecting packaging portion is disposed on an upstream end side of the item of packaging. 
     According to an eleventh aspect, a filling system having an unpacking system according to the seventh and the ninth aspect or one of the design embodiments thereof is proposed. 
     The packed objects have to be unpacked prior to further processing, for example filling or refilling in a filling station. The unpacking system described provides a simple and compact solution therefor, which also is implementable in a tight installation space. 
     In one refinement of the stretching device it can be provided that the projecting packaging portion in relation to the transportation direction is disposed on one of the end sides of the item of packaging, in particular wherein the packaging portion in relation to the transportation direction is disposed on a downstream end side. 
     On account of the disposal of the projecting packaging portion on the end sides, it can be avoided that the projecting packaging portion protrudes laterally beyond the width of the transportation installation. It is avoided in particular on account thereof that the projecting packaging portion catches on construction components or objects which are disposed laterally to the transportation installation. 
     In one further refinement of the stretching device it can be provided that the projecting packaging portion projects from the item of packaging so as to be substantially parallel with the transportation direction. 
     On account thereof, the retrieval of the projecting packaging portion between the lateral rollers of the holding installation is facilitated. 
     In one further refinement of the stretching device it can be provided that the motion installation is configured such that the latter holds the item of packaging on at least one longitudinal side. 
     To this end, the object can, for example, be in contact with the longitudinal side thereof that faces, with the motion installation, the transportation installation, and in particular can be disposed on the motion installation. In the case of a sufficiently high weight of the object, the static friction is sufficient in order for the object conjointly with the item of packaging for stretching to be moved away from the holding installation which holds the packaging portion, without the item of packaging overcoming the static friction and the tensile force exerted being reduced, for example by slippage on the motion installation, or being completely stopped, for example when the object leaves the motion installation, in particular when the object drops from the motion installation. Furthermore, the motion installation can hold the object on two or more sides, for example by means of a clamping force, which is exerted on two opposite longitudinal sides. The clamping force is herein to be chosen sufficiently high in order to stretch the item of packaging. 
     In one further refinement of the stretching device it can be provided that the motion installation is disposed on that side of the transportation installation that faces away from the item of packaging. 
     On account of disposal on that side of the transportation installation that faces away from the item of packaging, the space requirement of the stretching device laterally to the transportation installation is reduced. 
     In one further refinement of the stretching device it can be provided that the motion installation has at least one clamping installation or suction installation for holding the item of packaging. 
     The item of packaging is fixed to the motion installation on account of the clamping installation or the suction installation. Forces which are directed so as to be substantially parallel with the transportation direction act during the stretching of the item of packaging. The clamping installation or the suction installation is in particular provided in order for the object to remain fixed in terms of the position thereof on the motion installation and cannot slip on account of a tensile force which arises in the stretching procedure and which is counter to the movement direction of the motion installation. 
     Alternatively, it can also be provided that the item of packaging is held on the motion installation in a purely mechanical manner by friction, that is to say in particular by virtue of the weight of the object which pushes the item of packaging onto the transportation installation. 
     In one further refinement of the stretching device it can be provided that the at least two rollers are disposed so as to be mutually parallel. 
     The projecting packaging portion for stretching is to be disposed between the two rollers. If the two rollers are disposed so as to be parallel, placing the projecting packaging portion between the two rollers is simplified. 
     In one further refinement of the stretching device it can be provided that the at least two rollers are disposed downstream of the motion installation, wherein the motion installation is configured for moving the object counter to the transportation direction and away from the holding installation. 
     The objects typically are transported in the packed as well as the unpacked state in a transportation direction on a transportation installation. It is therefore advantageous for the objects to be retrieved from the item of packaging in the transportation direction. If the projecting packaging portion is now stretched in the transportation direction, in particular wherein the packaging portion is disposed on a downstream end side of the item of packaging, the subsequent operational steps such as opening the item of packaging are facilitated since, on account thereof, the item of packaging can be opened on the downstream end side without the item of packaging and the object having to be rotated on the transportation installation. 
     In one further refinement of the stretching device it can be provided that the at least two rollers are rotatably mounted. 
     The projecting packaging portion for stretching is disposed between the at least two rollers in order for the at least two rollers to be able to hold the projecting packaging portion. For disposal, the projecting packaging portion is moved between the at least two rollers. If the at least two rollers now are rotatably mounted, the rollers in the disposing action can conjointly rotate in the movement direction of the projecting packaging portion in order for the disposal of the projecting packaging portion between the rollers to be facilitated. 
     In one further refinement of the stretching device it can be provided that the at least two rollers are configured for drawing in therebetween the projecting packaging portion. 
     If the projecting packaging portion comes into contact with the rollers, the rollers in this instance are movable in such a manner that said rollers therebetween convey the packaging portion to the correct position. On account thereof, the disposal of the projecting packaging portion between the rollers is in particular furthermore simplified. 
     In one further refinement of the stretching device it can be provided that the holding installation has a rotary roller drive installation for rotating the at least two rollers. 
     The rotary roller driving installation can drive the rollers in such a manner that said rollers therebetween draw in the projecting packaging portion. On account thereof, the disposal of the projecting packaging portion between the rollers is in particular further simplified. 
     In one further refinement of the stretching device it can be provided that the rotary roller drive installation is configured for rotating the at least two rollers in mutually opposite running directions. 
     On account of the rollers being rotated in opposite directions, the drawing-in of the projecting packaging portion between the rollers is simplified. The holding installation preferably has exactly two rollers, wherein the exactly two rollers are driven in opposite running directions by the rotary roller drive installation. 
     In one further refinement of the stretching device it can be provided that the at least two rollers are movable relative to one another, in particular wherein the two rollers are configured for jamming therebetween the projecting packaging portion. 
     On account of the mutually relative movement the spacing between the rollers is capable of being set in a variable manner. It is advantageous herein for the relative mutual spacing of the rollers to be large when the projecting packaging portion is being introduced between the rollers. As soon as the projecting packaging portion is disposed between the rollers, the relative mutual spacing of the rollers can be decreased in such a manner that the projecting packaging portion is jammed between the rollers. 
     In one further refinement of the stretching device it can be provided that the holding installation has a translatory roller drive installation for moving the at least two rollers. 
     The translatory roller drive installation moves the rollers in particular in a mutually relative manner. The translatory roller drive installation can thus set the relative mutual spacing of the rollers in an arbitrary manner. 
     In one further refinement of the folding-out device according to the third aspect it can be provided that the holding installation is configured such that the latter holds the item of packaging on a longitudinal side that faces away from the transportation installation. 
     The packaging portion initially is folded inwards between the transportation installation and a longitudinal side of the item of packaging that faces the transportation installation. If the holding installation now engages the item of packaging on the longitudinal side that faces away from the transportation direction and draws the item of packaging in a direction that points away from the packaging portion, the packaging portion is thus folded outwards in a simple manner. The packaging portion herein is preferably connected to the remainder of the item of packaging on a downstream end side of the item of packaging. On account thereof, the packaging portion in a folded-out state projects from the downstream end side of the item of packaging. The holding installation preferably holds the item of packaging in a downstream region of the longitudinal side of the item of packaging that faces away from the transportation installation. For folding outwards, the holding installation in this instance is moved to an upstream region of the longitudinal side that faces away from the transportation direction. 
     In one further refinement of the folding-out device according to the third aspect it can be provided that the holding installation is disposed on that side of the transportation installation that faces the object. 
     On account of the holding installation being disposed on that side of the transportation installation that faces the object, the space requirement of the folding-out device laterally to the transportation installation is reduced. 
     In one further refinement of the folding-out device according to the third aspect it can be provided that the holding installation has at least one clamping installation or suction installation for holding the item of packaging. 
     On account of a clamping installation or suction installation, holding the item of packaging on an adjacent region can be implemented in a simple manner. The holding installation herein preferably has a suction installation. 
     In one further refinement of the folding-out device according to the third aspect it can be provided that the holding installation is movable parallel with the transportation direction, in particular in order for the packaging portion to be folded outwards, in particular wherein the holding-installation drive installation  68  is configured for moving the holding installation parallel with the transportation direction  20  and in particular counter thereto. 
     If the packaging portion is disposed on one of the end sides of the item of packaging and proceeding from the connecting point on the end side is folded inwards between the transportation installation and the longitudinal side that faces the transportation installation, a tensile force in or counter to the transportation direction, that is to say parallel with the transportation direction, that engages on the longitudinal side that faces away from the transportation installation is required in order for the packaging portion to be folded outwards. 
     In one further refinement of the folding-out device according to the third and the fifth aspect it can be provided that the lifting installation is disposed on that side of the transportation installation that faces away from the item of packaging. 
     On account thereof, the lifting installation has to be designed only such that said lifting installation engages the object including the item of packaging on the longitudinal side that faces the transportation installation and lifts said object including the item of packaging. Clamping, gripping, or holding the item of packaging and the object can be advantageous herein but is not mandatory when the static friction between the item of packaging and the lifting installation is sufficiently high. Furthermore, in the case of such a disposal of the lifting installation on that side of the transportation installation that faces away from the item of packaging, the space requirement laterally to the transportation installation is reduced. 
     In one further refinement of the folding-out device according to the third and the fifth aspect it can be provided that a transportation plane of the transportation installation has at least one clearance, wherein the lifting installation is configured for engaging through the clearance in order for the object to be raised. 
     On account thereof, the manner in which a lifting installation which is disposed on that side of the transportation installation that faces away from the item of packaging can engage on the item of packaging and the object on the longitudinal side that faces the transportation installation is implemented in a simple and compact manner. 
     In one further refinement of the folding-out device according to the third and the fifth aspect it can be provided that the lifting installation is configured for raising the transportation installation, in particular a transportation plane of the transportation installation, at least in the bearing region of the item of packaging on the transportation plane, in order for the object to be raised. 
     On account thereof, it is implemented in a simple manner how the object can be raised by the lifting installation. 
     In one further refinement of the folding-out device according to the third and the fifth aspect it can be provided that the lifting installation is configured such that the latter holds the item of packaging on at least one longitudinal side. 
     Since the holding installation holds the item of packaging in the folding-out procedure and herein is moved in a direction that points away from the packaging portion, it can be advantageous for the lifting installation to hold the item of packaging in order for the object not to move on the lifting installation when being folded outwards. 
     In one further refinement of the folding-out device according to the third and the fifth aspect it can be provided that the lifting installation has at least one clamping installation or one suction installation for holding the item of packaging. 
     On account of the clamping installation or the suction installation, the item of packaging is fixed to the lifting installation. Forces which are directed so as to be substantially parallel with the transportation direction act while the item of packaging is folded outwards. The clamping installation or the suction installation are in particular provided so that the object remains fixed in the position thereof on the lifting installation and cannot slip in the movement direction of the holding installation on account of tensile forces that arise in the folding-out procedure. 
     In one further refinement of the folding-out device according to the fifth aspect it can be provided that the detent installation has exactly two rollers, wherein a first roller of the two rollers is disposed on the longitudinal side of the item of packaging that faces the transportation installation, and a second roller of the two rollers is disposed on the longitudinal side of the item of packaging that faces away from the transportation installation. 
     In unpacking systems it can readily happen that in the unpacking of a plurality of objects in succession, the projecting packaging portion, depending on the object, is folded inwards either on that side of the item of packaging that faces the transportation installation or on that side of the item of packaging that faces away from the transportation installation. 
     On account of disposing in each case one roller on that side of the item of packaging that faces the transportation installation and on that side of the item of packaging that faces away from the transportation installation, it is ensured that always one roller can form a detent for the projecting and folded-in packaging portion. 
     In one further refinement of the folding-out device according to the fifth aspect it can be provided that the rollers are movable relative to one another. 
     It is achieved on account thereof that the two rollers initially can be spaced apart such that the item of packaging can be guided through between the rollers. Thereafter, the rollers can be brought to bear on the item of packaging and roll on the contour in the longitudinal direction of the item of packaging, so as on account thereof to completely fold outwards the folded-in packaging portion and to align the latter in the longitudinal direction. 
     In one further refinement of the folding-out device according to the fifth aspect it can be provided that the lifting installation has a horizontal drive which is configured for moving the lifting installation parallel with the transportation direction, in particular counter to the transportation direction. 
     On account of the movement of the lifting installation parallel with the transportation direction, the object and the item of packaging are moved parallel with the transportation direction. If the folded-in packaging portion bears on the roller, said folded-in packaging portion is folded outwards on account of a movement of this type. 
     The objects typically are transported in the packed as well as the unpacked state in a transportation direction on a transportation installation. It is therefore advantageous for the objects to be able to be retrieved from the item of packaging in the transportation direction. It is therefore advantageous for the packaging portion to be disposed on a downstream end side, to be folded outwards on account of a movement of the lifting installation counter to the transportation direction, and thus project in a downstream manner. On account thereof, opening the item of packaging is enabled on a downstream end of the item of packaging. 
     In one further refinement of the unpacking system according to the seventh and the ninth aspect it can be provided that the transportation installation is configured for transporting the object from the folding-out device to the stretching device. 
     The folding-out device and the stretching device typically are disposed in succession in a downstream manner, but herein do not have to be directly successive. The two devices herein can thus also be disposed so as to be locationally spaced apart from one another. It can therefore be advantageous for the transportation installation to transport the items of packaging having a folded-out packaging portion to the stretching device. 
     In one further refinement of the unpacking system according to the seventh and the ninth aspect it can be provided that the unpacking system has first support holders which are movable perpendicularly to and parallel with the transportation direction and which configure the lifting installation and the motion installation. 
     By virtue of the spatial restrictions for the unpacking system, and in order for the transportation path between individual devices of the unpacking system to be minimized, it can be advantageous for the folding-out device and the stretching device to be disposed so as to be as close to one another as possible, in particular wherein the two devices are disposed at the same location. It can therefore be advantageous for a movable support holder to configure the lifting installation of the folding-out device as well as the motion installation of the stretching device. It is thus possible for the folding-out device and the stretching device to be disposed so as to be as close to one another as possible. 
     In one further refinement of the unpacking system according to the ninth aspect it can be provided that the unpacking system has second support holders which are movable perpendicularly to and parallel with the transportation direction and which configure the holding installation and the detent installation. 
     It is enabled on account thereof that the rollers of the detent installation and the rollers of the holding installation are identical. This is advantageous in particular when the folding-out device and the stretching device are to be disposed as close as possible to one another. On account thereof, it is in particular possible for the operational steps of folding outwards and of stretching to be carried out in direct succession. The rollers to this end can be brought to bear on the two sides of the item of packaging, wherein one of the two rollers forms a detent for the folded-in packaging portion. The packaging portion can be folded outwards on account of a relative movement between the support holder and the object. The rollers in this instance can hold the projecting packaging portion and stretch the latter on account of a further relative movement, or on account of being drawn in between the rollers. 
     In one further refinement of the unpacking system according to the seventh and the ninth aspect, it can be provided that the transportation installation ahead of the folding-out device has a first deflection portion which causes a first directional change of the transportation direction, in particular wherein the first directional change is 90°. 
     By virtue of spatial restrictions in industrial sheds and of the restricted space for devices which can be disposed along a transportation installation, it may be impossible for the transportation installation to be able to run in a straight line. The transportation installation therefore preferably has deflection portions which cause a directional change of the transportation direction. The directional changes herein can assume any arbitrary value. In order for an ideally mutually symmetrical arrangement of all components to be achieved, it is advantageous for the directional change to be substantially 90°. 
     In one further refinement of the unpacking system according to the seventh and the ninth aspect it can be provided that the unpacking system furthermore has a severing device for completely severing the projecting and stretched packaging portion from the item of packaging. 
     The severing device is disposed downstream of the stretching device. On account of the packaging portion protruding and being stretched, on account of which the packaging portion in particular projects far from the item of packaging, the severing of the packaging portion by a severing device is facilitated. The severing device herein can have a holding installation for holding the projecting and stretched packaging portion, in order for the packaging portion to be fixedly held during the severing. However, said holding installation is not mandatory since the packaging portion on account of the stretching process projects far from the item of packaging. The severing device can preferably be disposed so as to be perpendicular to the transportation direction. 
     In one further refinement of the unpacking system according to the seventh and the ninth aspect, it can be provided that the severing device has a cutter, a laser, or a thermal separation method for completely severing the packaging portion. 
     Holding the packaging portion in a separate manner is not required in particular in the case of a laser or of a thermal separation method. A separate holding installation can in this instance be of advantage when the severed packaging portion is discarded in a targeted manner by means of the holding installation. 
     In one further refinement of the unpacking system according to the seventh and the ninth aspect it can be provided that the severing device has a retrieving installation for retrieving the object from the item of packaging. 
     The retrieving installation herein can have holding means, for example a clamping installation, for holding the item of packaging, in particular on a side that is opposite the open side of the item of packaging. The retrieving installation can furthermore have a gripping installation for removing the object from the item of packaging. Alternatively, the item of packaging can be drawn away from the object by means of a gripping installation, in order for the item of packaging to be removed from the object. 
     In one further refinement of the unpacking system according to the seventh and the ninth aspect it can be provided that the severing device has a discarding installation which is configured for discarding the severed packaging portion and the remainder of the item of packaging. 
     The discarding device herein can have one or a plurality of grippers which moves/move the packaging parts away from the severing device. The discarding installation can also have a conveyor belt or another transportation installation which conveys the remainders of packaging away from the severing device. To this end, grippers can be configured herein for placing the remainders of packaging onto the conveyor belt. Alternatively, the discarding installation could also be configured by means of a suction installation which suctions the remainders of packaging and thus transports the latter away from the severing device. 
     In one further refinement of the unpacking system according to the seventh and the ninth aspect it can be provided that the transportation installation is configured for transporting the object from the stretching device to the severing device, in particular wherein the transportation installation between the stretching device and the severing device has a second deflection portion which causes a second directional change of the transportation direction, in particular wherein the second directional change is 90°. 
     By virtue of the spatial arrangement of the device it can be advantageous for the stretching device and the severing device to be placed so as to be mutually separate in spatial terms. On account thereof, it becomes necessary for the objects including the item of packaging to be moved from the stretching device to the severing device. The transportation installation which can run between the stretching device and the severing device offers one possibility for transporting the object from the stretching device to the severing device. In one advantageous refinement, the severing device and the stretching device in relation to the transportation direction can be disposed at a mutual angle. This is of importance in particular when the available space, for instance in an industrial shed in which the packaging system is disposed, is limited. In this case it is advantageous for the transportation installation to have a deflection portion in which the transportation direction is changed. 
     In one further refinement of the unpacking system according to the seventh and the ninth aspect it can be provided that the transportation installation is configured for transporting the object away from the severing device, in particular wherein the transportation installation upstream of, in, or downstream of the severing device has a third deflection portion which causes a third directional change of the transportation direction, in particular wherein the third directional change is 90°. 
     A continuous transportation installation which transports the object to all devices and away from all devices is thus provided. By virtue of spatial restrictions in industrial sheds and of the restricted space for devices which may be disposed along a transportation installation, it may be impossible for the transportation installation to run in a straight line. The transportation installation therefore preferably has the third deflection portion which causes a directional change of the transportation direction. The directional change herein can assume any arbitrary value. In order for an ideally mutually symmetrical arrangement of all components to be achieved it is advantageous for the directional change to be substantially 90°. 
     In one further refinement of the unpacking system according to the seventh and the ninth aspect it can be provided that the transportation installation is configured for transporting the unpacked objects from the severing device into a cleanroom. 
     In particular in the pharmaceutical and cosmetic sector in which unpacking systems are used, deliveries of such packed objects arrive in a non-sterile region. Unpacking is then carried out in the non-sterile region. It is therefore advantageous for the severing device to be disposed so as to be as close as possible to a cleanroom. It is therefore advantageous for the transportation installation downstream of the severing device to run directly into a cleanroom without the objects having to be transferred to another transportation installation, transported to another operational step onto another device in the non-sterile region, or transported across a vast distance. 
     In one further refinement of the method for stretching it can be provided that in the step of moving a motion installation holds the item of packaging on at least one longitudinal side. 
     To this end, the object can, for example, be in contact with the longitudinal side thereof that faces, with the motion installation, the transportation installation, and in particular can be disposed on the motion installation. In the case of a sufficiently high weight of the object, the static friction is sufficient in order for the object conjointly with the item of packaging for stretching to be moved away from the holding installation which holds the packaging portion, without the item of packaging overcoming the static friction and the tensile force exerted being reduced, for example by slippage on the motion installation, or being completely stopped, for example when the object leaves the motion installation, in particular when the object drops from the motion installation. Furthermore, the motion installation can hold the object on two or more sides, for example by means of a clamping force, which is exerted on two opposite longitudinal sides. The clamping force is herein to be chosen sufficiently high in order to stretch the item of packaging. 
     In one further refinement of the method for stretching it can be provided that the projecting packaging portion in relation to the transportation direction is disposed on the downstream end side, wherein in the step of moving the object is moved counter to the transportation direction and away from the holding installation. 
     The objects typically are transported in the packed as well as the unpacked state in a transportation direction on the transportation installation. It is therefore advantageous for the objects to be able to be retrieved from the item of packaging in the transportation direction. If the projecting packaging portion is now stretched in the transportation direction, in particular wherein the packaging portion is disposed on a downstream end side of the item of packaging, the subsequent operational steps such as opening the item of packaging are facilitated since, on account thereof, the item of packaging can be opened on the downstream end side without the item of packaging and the object having to be rotated on the transportation installation. 
     In one further refinement of the method for stretching it can be provided that in the step of holding the at least two rollers therebetween draw in the projecting packaging portion. 
     If the projecting packaging portion comes into contact with the rollers, the rollers are moved in such a manner that the latter therebetween convey the packaging portion to the correct position. On account thereof, the disposal of the projecting packaging portion between the rollers is in particular further simplified. 
     In one further refinement of the method for stretching it can be provided that in the step of holding the at least two rollers are rotated in mutually opposite directions, on account of which the projecting packaging portion is drawn in between the at least two rollers. 
     The drawing-in of the projecting packaging portion between the rollers is simplified on account of the counter-rotation of the rollers. The holding installation preferably has exactly two rollers, wherein the exactly two rollers are driven in opposite running directions. 
     In one further refinement of the method for stretching it can be provided that in the step of holding the at least two rollers are moved relative to one another, on account of which the at least two rollers therebetween jam the projecting packaging portion. 
     The spacing between the rollers becomes capable of being set in a variable manner on account of the mutually relative movement. It is advantageous herein for the relative mutual spacing of the rollers to be large when the projecting packaging portion is introduced between the rollers. As soon as the projecting packaging portion is disposed between the rollers, the relative mutual spacing of the rollers can be decreased in such a manner that the projecting packaging portion is jammed between the rollers. 
     In one further refinement of the method for folding outwards according to the fourth aspect it can be provided that in the step of holding the holding installation holds the item of packaging on a longitudinal side that faces away from the transportation installation. 
     The packaging portion initially is folded inwards between the transportation installation and a longitudinal side of the item of packaging that faces the transportation installation. If the holding installation now engages the item of packaging on the longitudinal side that faces away from the transportation installation and draws the item of packaging in a direction that points away from the packaging portion, the packaging portion is thus folded outwards in a simple manner. The packaging portion herein is preferably connected to the remainder of the item of packaging on a downstream end side of the item of packaging. On account thereof, the packaging portion in a folded-out state projects from the downstream end side of the item of packaging. The holding installation preferably holds the item of packaging in a downstream region of the longitudinal side of the item of packaging that faces away from the transportation installation. For folding outwards, the holding installation in this instance is moved to an upstream region of the longitudinal side that faces away from the transportation installation. 
     In one further refinement of the method for folding outwards according to the fourth aspect it can be provided that in the step of moving the holding installation is moved parallel with the transportation direction and in particular counter thereto, on account of which the packaging portion is folded outwards. 
     If the packaging portion is disposed on one of the end sides of the item of packaging and proceeding from the connecting point on the end side is folded inwards between the transportation installation and the longitudinal side that faces the transportation installation, a tensile force in or counter to the transportation direction, that is to say parallel with the transportation direction, is advantageous in order for the packaging portion to be folded outwards. 
     In one further refinement of the method for folding outwards according to the fourth and the sixth aspect it can be provided that in the step of raising the lifting installation holds the item of packaging on at least one longitudinal side. 
     Since the holding installation holds the item of packaging in the folding-out procedure and herein is moved in a direction that points away from the packaging portion, it can be advantageous for the lifting installation to hold the item of packaging in order for the object not to move on the lifting installation when being folded outwards. 
     It is to be understood that the afore-mentioned features and those yet to be explained hereunder can be used not only in the combination stated in each case, but also in other combinations or individually, without departing from the scope of the present invention.

     DETAILED DESCRIPTION OF THE INVENTION 
       FIGS. 1A, 1B, 2, and 3  shows an embodiment of a stretching device  10 . The stretching device  10  is configured for stretching an item of packaging  12 . An object  14  is packed in the item of packaging  12 . The item of packaging  12  has a packaging portion  16  which is disposed on the side of the item of packaging  12  and projects from the item of packaging  12 . The stretching device  10  has a transportation installation  18 , a holding installation  22 , and a motion installation  24 . 
     The transportation installation  18  is configured for transporting the object  14  in a transportation direction  20 . The item of packaging  12  in relation to the transportation direction  20  has an upstream end side  28 ″ and a downstream end side  28 ′. The item of packaging  12  in relation to the transportation direction  20  furthermore has four longitudinal sides  30 ′,  30 ″,  30 ′″, and  30 ″″. A longitudinal side  30 ′ that faces the transportation installation ( 18 ) herein faces the transportation installation  18  and is at least partially in contact with the transportation installation  18 . The item of packaging  12  by way of the longitudinal side  30 ′ that faces the transportation installation ( 18 ) accordingly bears on the transportation installation  18 . A longitudinal side  30 ′″ that faces away from the transportation installation ( 18 ) faces away from the transportation installation  18 . Two lateral longitudinal sides  30 ″ and  30 ′″ are disposed laterally to the transportation installation  18  and lie so as to be substantially perpendicular on the transportation installation  18 . The projecting packaging portion  16  is disposed on the downstream end side  28 ′ of the item of packaging  12 . The transportation installation  18  has a transportation plane  38  on which the object  14  and the item of packaging  12  are transported. 
     The transportation installation  18  furthermore has clearances  40  on the two peripheries of the transportation plane  38  such that the item of packaging  12  and the object  14  bear on the transportation installation  18  and the transportation plane  38  only in a central region. 
     The holding installation  22  has two rollers  26 ′,  26 ″ that are disposed so as to be perpendicular to the transportation direction  18 . The two rollers  26 ′,  26 ″ are disposed so as to be mutually parallel. The two rollers  26 ′,  26 ″ are disposed so as to be parallel with the transportation plane  38 . The holding installation  22  furthermore has a rotary roller drive installation  34  for rotating the rollers  26 ′,  26 ″, and a translatory roller drive installation  36  for moving the rollers  26 ′,  26 ″. The holding installation  22  furthermore has a roller support installation  42  in which the rollers  26 ′,  26 ″ are disposed so as to be rotatable and movable relative to one another. The roller support installation  42  herein configures the rotary roller drive installation  34  and the translatory roller drive installation  26 . The rotary roller drive installation  34  can preferably drive the rollers  26 ′,  26 ″ in opposite directions. The projecting packaging portion can be drawn in between the rollers on account of the counter-rotation of the rollers  26 ′,  26 ″. The translatory roller drive installation  36  is configured for moving the rollers relative to one another. This relative movement in this exemplary embodiment is in particular performed perpendicularly to the transportation plane  38 . It can be particularly advantageous herein for the spacing between the rollers to be large when the projecting packaging portion is being introduced, and for the rollers after the introduction of the packaging portion to be moved towards one another in order for the projecting packaging portion to be jammed therebetween. The invention herein is however not restricted to two rollers. Three, four, five or more rollers can also be disposed in an alternative design embodiment in order for the projecting packaging portion to be held therebetween. 
     The motion installation  24  is configured for moving the object  14  conjointly with the item of packaging  12 . The motion installation  24  to this end has a vertical drive  44  for a vertical movement that is perpendicular to the transportation plane  38 , and a horizontal drive  46  for a movement that is parallel with the transportation plane  38 , in particular parallel with the transportation direction  20 . The motion installation  24  in the embodiment illustrated furthermore has a clamping installation  32  which is configured for jamming therebetween the item of packaging  12  and the object  14 . The clamping installation  32  to this end has lifting elements  48 ′,  48 ″, and a detent element  50 . The lifting elements  48 ′,  48 ″ are disposed such that said lifting elements  48 ′,  48 ″ in the case of a vertical movement that is perpendicular to the transportation plane  38  are moved through the two clearances  40  of the transportation plane  38 . The lifting elements  48 ′,  48 ″ have a contact face  52  which comes into contact with the longitudinal side  30 ′ of the item of packaging  12  that faces the transportation installation ( 18 ). The contact face  52  herein, in particular in an upstream region of the longitudinal side  30 ′ that faces the transportation installation ( 18 ) comes to bear on the longitudinal side  30 ′ that faces the transportation installation ( 18 ). The vertical drive  44  is configured for moving the lifting elements  48 ′,  48 ″ perpendicularly to the transportation plane  38 . The object  14  conjointly with the item of packaging  12  is thus movable perpendicularly to the transportation plane  38 . The detent element  50  has a bearing face  54  on which the item of packaging  12  by way of the longitudinal side  30 ′″ that faces away from the transportation installation ( 18 ) comes to bear when clamped. The bearing face  54  herein comes to bear on the longitudinal side  30 ′″ that faces away from the transportation installation ( 18 ) in particular in an upstream region of the longitudinal side  30 ′″ that faces away from the transportation installation ( 18 ). On account thereof, the item of packaging  12  and the object  14  are held between the lifting elements  48 ′,  48 ″, and the detent element  50 . The motion installation  24  furthermore has a frame  56  which includes the detent element  50  and connects the detent element  50  to the remaining components of the motion installation  24 , said remaining components largely being disposed on that side of the transportation installation ( 18 ) that faces away from the item of packaging. The frame  56 , proceeding from the transportation plane  38 , has a height  57 ′ which is greater than a height  13 ′ of the item of packaging  12 . On account thereof, it can be avoided that the item of packaging  12  when transported on the transportation plane  18  comes into contact with the detent element  50 , in particular scrapes along the latter or catches on the latter. Contact between the item of packaging  12  and the detent element  50  is established only when the item of packaging  12  by way of the lifting elements  48 ′,  48 ″ is moved vertically away from the transportation plane  38  and comes to bear on the detent element  50 . The frame  56  furthermore has a width  57 ″ which is greater than a width  13 ″ of the item of packaging  12  and is greater than a width  19  of the transportation installation  18 . It can be avoided on account thereof that the item of packaging  12  when transported laterally comes into contact with the frame  56 , in particular scrapes along the latter or catches on the latter. 
     The horizontal drive  46  of the motion installation  24  is configured for moving the item of packaging  12  and the object  14  parallel with the transportation plane  38 , in particular parallel with the transportation direction  20 . The horizontal drive  46  herein moves the lifting elements  48 ′,  48 ″ as well as the frame  56  having the detent element  50  in the horizontal direction. It is enabled on account thereof that the item of packaging is simultaneously clamped by the clamping installation  32  while said item of packaging is moved parallel with the transportation plane  38 , in particular parallel with the transportation direction  20 . 
     The motion installation  24  can be configured for moving the object  14  and the item of packaging  12  towards the rollers  26 ′,  26 ″ in order for the projecting packaging portion  16  to be guided through between the two rollers  26 ′,  26 ″. A central plane  58  which lies so as to be parallel with the transportation plane and which is equidistant from the rollers  26 ′,  26 ″ lies between the two rollers  26 ′,  26 ″. In one advantageous design embodiment, the projecting packaging portion  16  while being clamped in the clamping installation  32  of the motion installation  24  is disposed such that said projecting packaging portion  16  lies in the central plane  58 . On account thereof, it is achieved in a simple manner that the projecting packaging portion  16  can be guided through the intermediate space between the two rollers  26 ′,  26 ″. If the projecting packaging portion  16  is not disposed in the central plane  58 , the rollers  26 ′,  26 ″ can be mutually spaced further apart by means of the translatory roller drive installation  36 , in order for a larger intermediate space, through which the projecting packaging portion  16  can be guided, to be generated between the rollers  26 ′,  26 ″. In one alternative design embodiment, it can be provided that the rollers  26 ′,  26 ″ are movable not only relative to one another but also in a conjoint parallel manner perpendicularly to the transportation plane  38 . On account thereof it is enabled that the central plane  58  which lies between the rollers  26 ′,  26 ″ can be displaced at the height of the projecting packaging portion  16 . 
     Alternatively or additionally to the embodiment of a stretching device  10  described in  FIGS. 1A, 1B, 2, and 3 , it can be provided that, instead of or in addition to the motion installation  24 , the holding installation  22  is movable parallel with the transportation direction  20 . To this end, the holding installation  22  can have a horizontal drive, for example, which can move the holding installation  22  parallel with the transportation direction  20 . On account thereof, the object  14  and the holding installation  22  are moved away relative to one another, and the packaging portion  16  on account thereof can be likewise stretched. 
       FIG. 4  shows an embodiment of a method  160  for stretching an item of packaging  12 , in particular a pouch, for an object  14 , in particular a pharmaceutical or cosmetic object. The stretching device  10  which is described in  FIGS. 1A to 3  is in particular suitable for carrying out the method  160  for stretching. The item of packaging  12  to be stretched herein has a projecting packaging portion  16 . The object  14  is transported in a transportation direction  20  on a transportation installation  18 . The individual method steps will be described in more detail hereunder. 
     In a first step  162  the projecting packaging portion  16  is held by a holding installation  22 . The holding installation  22  has two rollers  26 ′,  26 ″ that are disposed so as to be perpendicular to the transportation direction  20 . The projecting packaging portion  16  is held between the two rollers  26 ′,  26 ″. The invention herein is however not restricted to two rollers. Three, four, five or more rollers can also be disposed in an alternative design embodiment in order for the projecting packaging portion to be held therebetween. 
     In a second step  164  the object  14  is moved away from the holding installation  22  and parallel with the transportation installation  20 . The projecting packaging portion  16  is stretched in this movement, since said projecting packaging portion  16  is held between the rollers  26 ′,  26 ″. 
     Alternatively or additionally, in the second step  164  the holding installation  22  can also be moved parallel with the transportation direction  20  and away from the object  14 . The projecting packaging portion  16  is likewise stretched in this movement, since said projecting packaging portion  16  is held between the rollers  26 ′,  26 ″. 
     In the first step of moving  164  the item of packaging  12  is preferably held on at least one longitudinal side  30 ′,  30 ″,  30 ′″,  30 ″″ by a motion installation  24 . The motion installation  24  can be configured in particular as such a motion installation as has been described in the stretching device  10  in  FIGS. 1A to 3 . 
     The projecting packaging portion  16  in relation to the transportation direction  20  is preferably disposed on the downstream end side  28 ′. The object  14  herein in the second step of moving  164  is moved counter to the transportation direction  20  and away from the holding installation  22 . 
     The rollers  26 ′,  26 ″ in the step of holding  162  are preferably rotated in opposite directions, on account of which the projecting packaging portion  16  is drawn in between the rollers  26 ′,  26 ″. 
     The rollers  26 ′,  26 ″ in the step of holding  162  are preferably moved in a relative manner towards one another, on account of which the rollers  26 ′,  26 ″ therebetween jam the projecting packaging portion  16 . 
       FIGS. 5 a  to 5 d    show an isometric illustration of the individual method steps of the method  160  for stretching an item of packaging  12 , said method  160  being described in  FIG. 4 . 
       FIG. 5 a    herein shows a first part-step of the step  162  of holding, wherein a downstream region of the projecting packaging portion  16  is disposed between the rollers  26 ′,  26 ″. The downstream region of the packaging portion  16  herein is preferably disposed between the rollers  26 ′,  26 ″ in that the motion installation  24  moves the item of packaging  12  parallel with the transportation direction  20  towards the rollers and introduces the projecting packaging portion  16  between the rollers  26 ′,  26 ″. 
       FIG. 5 b    shows a second part-step of the step  162  of holding, in which the projecting packaging portion  16  is drawn in between the rollers  26 ′,  26 ″. The rollers  26 ′,  26 ″ herein are moved in a relative manner towards one another until they are in contact with the projecting packaging portion  16 . The rollers  26 ′,  26 ″ in this instance are rotated in opposite directions in order for the projecting packaging portion  16  to be drawn in therebetween in the transportation direction  20 . 
       FIG. 5 c    shows an isometric illustration of a third part-step of the step  162  of holding, in which the projecting packaging portion  16  is held between the rollers  26 ′,  26 ″. The rollers  26 ′,  26 ″ herein in a first design embodiment can be mutually compressed in order for the projecting packaging portion  16  to be jammed therebetween. In one alternative design embodiment the rollers  26 ′,  26 ″ can be configured so as to continuously counter-rotate in order for a uniform and consistent tensile force to thus be exerted on the projecting packaging portion  16 . On account of this tensile force, the projecting packaging portion  16  can likewise be held between the rollers  26 ′,  26 ″. In a further design embodiment, the packaging portion  16  can be held between the rollers  26 ′,  26 ″ in particular by way of a consistent uniform mutual counter-rotation of the rollers  26 ′,  26 ″ and a mutual compression of the rollers  26 ′,  26 ″. 
       FIG. 5 d    shows an isometric illustration of the step  164  of moving, in which the item of packaging  12  and the object  14  by the motion installation  24  are moved away from the rollers  26 ′,  26 ″, on account of which the projecting packaging portion  16  and a part-region of the downstream end side  28 ′ of the item of packaging  12  are stretched. 
       FIGS. 6A, 6B, 7, and 8  show an embodiment of a folding-out device  60 ′. The folding-out device  60 ′ is configured for folding outwards a folded-in packaging portion  16  of an item of packaging  12 . An object  14  is packed in the item of packaging  12 . The folding-out device  60 ′ has a transportation installation  18 , a lifting installation  62 , a holding installation  64 , and a holding-installation drive installation  68 . 
     The transportation installation  18  is configured for transporting the object  14  in a transportation direction  20 . The item of packaging  12  in relation to the transportation direction  20  has an upstream end side  28 ″ and a downstream end side  28 ′. The item of packaging  12  in relation to the transportation direction  20  furthermore has four longitudinal sides  30 ′,  30 ″,  30 ′″, and  30 ″″. A longitudinal side  30 ′ that faces the transportation installation ( 18 ) herein faces the transportation installation and is at least partially in contact with the transportation installation  18 . The item of packaging  12  by way of the longitudinal side  30 ′ that faces the transportation installation ( 18 ) accordingly bears on the transportation installation  18 . An upper longitudinal side  30 ′″ faces away from the transportation installation  18 . Two lateral longitudinal sides  30 ″ and  30 ′″ are disposed laterally to the transportation installation  18  and lies so as to be substantially perpendicular on the transportation installation  18 . The packaging portion  16  is connected to the remainder of the item of packaging on the downstream end side  28 ′ of the item of packaging  12 . The packaging portion  16  initially extends along the downstream end side  28 ′ in the direction of the longitudinal side  30 ′ of the item of packaging  12  that faces the transportation installation ( 18 ), and further partially along the longitudinal side  30 ′ of the item of packaging  12  that faces the transportation installation ( 18 ). The packaging portion  16  is thus partially disposed between the longitudinal side  30 ′ of the item of packaging  12  that faces the transportation installation ( 18 ) and the transportation installation  18 . The packaging portion  16  initially is thus folded inwards between the transportation installation  18  and the longitudinal side  30 ′ of the item of packaging  12  that faces the transportation installation ( 18 ). The transportation installation  18  has a transportation plane  38  on which the object  14  and the item of packaging  12  are transported. 
     The transportation installation  38  furthermore has clearances  40  on the two peripheries of the transportation plane  38 , such that the item of packaging  12  and the object  14  bear on the transportation installation  18  and on the transportation plane  38  only in a central region. 
     The lifting installation  62  is configured for raising the object  14  conjointly with the item of packaging  12 . To this end, the lifting installation  62  has a vertical drive  76  for vertically moving the object perpendicularly to the transportation plane  38 . The lifting installation  62  in the embodiment illustrated furthermore has a clamping installation  74  which is configured for therebetween jamming the item of packaging  12  and the object  14 . To this end, the clamping installation  74  has lifting elements  78 ′,  78 ″, and a detent element  80 . The lifting elements  78 ′,  78 ″ are disposed such that said lifting elements  78 ′,  78 ″ in a vertical movement perpendicular to the transportation plane  78  are moved through the two clearances  40  of the transportation plane  38 . The lifting elements  78 ′,  78 ″ have a contact face  82  which come into contact with the longitudinal side  30 ′ of the item of packaging  12  that faces the transportation installation ( 18 ). The contact face  82 , in particular in an upstream region of the longitudinal side  30 ′ that faces the transportation installation ( 18 ), herein comes to bear on the longitudinal side  30 ′ that faces the transportation installation ( 18 ). The vertical drive  76  is configured for moving the lifting elements  78 ′,  78 ″ perpendicularly to the transportation plane  38 . The object  14  can therefore be moved conjointly with the item of packaging  12  perpendicularly to the transportation plane  38 . The detent element  80  has a bearing face  84  on which the item of packaging  12  by way of the longitudinal side  30 ′″ that faces away from the transportation installation ( 18 ) comes to bear when clamped. The bearing face  84  herein comes to bear on the longitudinal side  30 ′″ that faces away from the transportation installation ( 18 ) in particular in a downstream region of the longitudinal side  30 ′″ that faces away from the transportation installation ( 18 ). On account thereof, the item of packaging  12  and the object  14  are held between the lifting elements  78 ′,  78 ″ and the detent element  80 . The lifting installation  62  furthermore has a frame  86  which includes the detent element  80  and connects the detent element  80  to the remaining components of the lifting installation  62 , said remaining components largely being disposed on that side of the transportation installation  18  that faces away from the item of packaging ( 12 ). The frame  86 , proceeding from the transportation plane  38 , has a height  87 ′ which is greater than a height  13 ′ of the item of packaging  12 . It can be avoided on account thereof that the item of packaging  12  when transported on the transportation plane  38  comes into contact with the detent element  80 , in particular scrapes along the latter or catches on the latter. A contact between the item of packaging  12  and the detent element  80  can be established only when the item of packaging  12  by way of the lifting elements  78 ′,  78 ″ is moved vertically away from the transportation plane  38  and comes to bear on the detent element  80 . The frame  86  furthermore has a width  87 ″ which is greater than a width  13 ″ of the item of packaging  12  and is greater than a width  19  of the transportation installation  18 . It can be avoided on account thereof that the item of packaging  12  when transported laterally comes into contact with the frame  86 , in particular scrapes along the latter or catches on the latter. 
     The holding installation  64  has a suction installation  72  which suctions and holds a region  66  of the item of packaging  12  that is adjacent to the packaging portion  16 . In the embodiment illustrated, the adjacent region  66  corresponds to a downstream region of the longitudinal side  30 ′″ that faces away from the transportation installation ( 18 ). The suction installation  72  furthermore has a suction head  90 , a hose  88 , and an installation for generating a vacuum (not illustrated). The suction head  90  bears on the adjacent region  66  in order for the latter to be suctioned. The hose  88  connects the suction head  90  to the installation for generating a vacuum (not illustrated). The installation for generating a vacuum can be a vacuum pump, for example. 
     The holding-installation drive installation  68  is configured for moving the suction installation  72  parallel with the transportation direction  20 . The holding-installation drive installation  68  herein can move the suction installation counter to the transportation direction when the suction installation  72  suctions and holds the adjacent region  66  of the item of packaging  12 . On account thereof, the folded-in packaging portion  16  is folded outwards. The holding-installation drive installation  68  can furthermore be configured for moving the suction installation  72  by means of a pivoting movement or a lifting movement. 
     Alternatively to the embodiment of a folding-out device  60 ′ described in  FIGS. 6A, 6B, 7, and 8 , it can be provided that the initially folded-in packaging portion  16  instead of being folded inwards onto that side of the item of packaging  12  that faces the transportation installation  18  is folded inwards onto the longitudinal side  30 ′″ of the item of packaging  12  that faces away from the transportation installation  18 . Accordingly, the holding installation  62  is also disposed on the longitudinal side  30 ′ of the item of packaging  12  that faces the transportation installation  18  and engages on the longitudinal side  30 ′ of the item of packaging  12  that faces the transportation installation  18 , wherein the longitudinal side  30 ′ that faces the transportation installation  18  is an adjacent region  66  of the packaging portion  16 . The folded-in packaging portion can likewise be folded outwards by way of such an arrangement. 
       FIG. 9  shows an embodiment of a method  180 ′ for folding outwards a packaging part  16  of an item of packaging  12 , in particular a pouch, for an object  14 , in particular a pharmaceutical or cosmetic object. The folding-out device  60 ′ which is described in  FIGS. 6A to 8  is in particular suitable for carrying out the method  180 ′ for folding outwards. The object  14  herein is transported in a transportation direction  20  on a transportation installation  18 . The packaging portion  16  initially is folded inwards between the transportation installation  18  and the item of packaging  12 , in particular a longitudinal side  30 ′ of the item of packaging  12  that faces the transportation installation ( 18 ). The individual method steps will be described in more detail hereunder. 
     In a first step  182  the object  14  is raised from the transportation installation  18  by a lifting installation  62 . The lifting installation  62  herein on that side of the item of packaging that faces away from the transportation installation ( 18 ) can have a detent element  80  against which the item of packaging  12  and the object  14  are pushed in the raising  182  of the object  14 . The lifting installation  62  is in particular configured for raising and holding the item of packaging  12  of the object  14 . 
     The lifting installation  62  in the step of raising  182  preferably holds the item of packaging  12  on at least one lateral face  30 ′,  30 ″,  30 ′″,  30 ″″. 
     Alternatively or additionally, the lifting installation  62  in the first step  182  can also raise the transportation installation  18 , in particular the transportation plane  38  of the transportation installation  18 , at least in the bearing region of the item of packaging  12  on the transportation plane  38 . 
     In a second step  184  a region  66  of the item of packaging  12  that is adjacent to the packaging portion  16  is held by a holding installation  64 . The adjacent region  66  herein corresponds in particular to a downstream region of the longitudinal side  30 ′″ that faces away from the transportation installation ( 18 ). The holding installation  64  can preferably have a suction installation  72  which suctions and holds the adjacent region  66 . 
     The holding installation  64  in the step of holding  184  preferably holds the item of packaging  12  on the longitudinal side  30 ′″ that faces away from the transportation installation ( 18 ). 
     In a third step  186  the holding installation  64  is moved in a direction  70  that points away from the packaging portion  16 . A tensile force which draws the folded-in packaging portion  16  from the folded-in position thereof between the transport installation  18  and the item of packaging  12  and thus folds said folded-in packaging portion  16  outwards is exerted on the folded-in packaging portion  16  in this movement. 
     The holding device  64  in the step of moving  186  is preferably moved parallel with the transportation direction  20 , on account of which the packaging portion  16  is folded outwards. 
       FIGS. 10 a  to 10 c    show an isometric illustration of the individual method steps of the method  180 ′ for folding outwards the packaging portion  16 , said method  180 ′ being described in  FIG. 9 . 
       FIG. 10 a    shows the step of raising  182 , in which the lifting installation  62  is disposed on that side of the object  14  that faces the transportation installation ( 18 ) and on account of a movement that is perpendicular to the transportation plane  38  is configured for raising the object  14  and the item of packaging  12 . In one advantageous design embodiment, the longitudinal side  30 ′″ that faces away from the transportation installation ( 18 ) herein is pushed against a detent element  80 . The detent element  80  herein comes into contact with an upstream region of the longitudinal side  30 ′″ that faces away from the transportation installation ( 18 ). On account of the lifting installation  64  pushing the object  14  and the item of packaging  12  against the detent element  80 , the object  14  and the item of packaging  12  are clamped and held on account thereof. 
       FIG. 10 b    shows an isometric illustration of the step of holding  184 , in which a suction installation  72  suctions a downstream region of the longitudinal side  30 ′″ that faces away from the transportation installation ( 18 ). The folded-in packaging portion on the downstream end side  28 ′ is connected to the item of packaging  12 . The downstream region of the longitudinal side  30 ′″ that faces away from the transportation installation ( 18 ) thus corresponds to a region  66  that is adjacent to the packaging portion  16 . 
       FIG. 10 c    shows an isometric illustration of the step of moving  186 , in which the holding installation by means of a holding-installation drive installation is moved counter to the transportation direction  20  and away from the packaging portion  16 . The suction installation  72  herein is in particular moved towards the detent element  80  of the lifting installation  62 . On account of this movement, the folded-in packaging portion  16  is drawn out from a folded-in position between the transportation installation  18  and the longitudinal side  30 ′ that faces the transportation installation ( 18 ) and is folded outwards. 
       FIG. 11  shows an embodiment of an unpacking system  100 . The unpacking system  100  has a transportation installation  18 , a folding-out device  60 , a stretching device  10 , and a severing device  108 . 
     The folding-out device  60  herein can be formed either by the embodiment of a folding-out device  60 ′ described in  FIGS. 6A, 6B, 7, 8 , or by the embodiment of a folding-out device  60 ″ described in  FIGS. 14A, 14B, 15, 16 . 
     The transportation installation  18  has a transportation plane  38  on which an object  14 , in particular a pharmaceutical or cosmetic object, is transported. The object is packed in an item of packaging, in particular a pouch. The item of packaging  12  has a packaging portion  16  which initially is folded inwards between the transportation installation  18  and the item of packaging  12 . The object  14  is transported in a transportation direction  20  on the transportation installation  18 . The transportation installation  18  is configured for transporting the packed object  14  towards the folding-out device  60 , from the stretching device  10  to the severing device  108 , and away from the severing device  108 . The folding-out device  60  and the stretching device  10  herein are disposed to as to be directly beside one another. The unpacking system  100  herein can in particular have one or a plurality of first movable support holders  102  which configure the lifting installation  64  of the folding-out device  60 , and the motion installation  24  of the stretching device  10 . The unpacking system  100  can furthermore in particular have one or a plurality of second movable support holders  103  which configure the detent installation  92  of the folding-out device  60 ″ and the holding installation  22  of the stretching device  10 . The first and the second support holders  102 ,  103  can in particular be movable perpendicularly to and/or parallel with the transportation direction. 
     In one alternative embodiment it can also be provided that the stretching device  10  and the folding-out device  60  are disposed so as to be mutually spaced apart, and the transportation installation  18  is configured for transporting the object  14  from the folding-out device  60  to the stretching device  10 . 
     The severing device  108  has a cutter, a retrieving device, and a discarding installation. The cutter is disposed such that said cutter is movable perpendicularly to the transportation direction in order for the projecting packaging portion  16  to be cut off and for the item of packaging  12  thus to be open. In one alternative design embodiment, a laser, a gripping blade, or a thermal separation method such as, for example, a hot wire or hot air, can also be used instead of the cutter in order for the projecting packaging portion  16  to be severed from the item of packaging  12 . The retrieving installation is configured for retrieving the object  14  from the item of packaging  12 , that is to say that the retrieving installation is thus configured for mutually separating the object  14  and the item of packaging  12 . Various methods for retrieving an object from an opened item of packaging are known in the prior art. For example, to this end a holding installation can hold the item of packaging, and a gripping installation can retrieve the object from the item of packaging. Alternatively, the object can be fixedly held by a holding installation while a gripping installation holds the item of packaging and pulls the item of packaging down from the object  14 . 
     The discarding installation is configured for discarding the severed packaging portion  16  and the remainder of the item of packaging  12 . The two separated packaging parts of the item of packaging  12  herein can be discarded in a mutually separate manner or collectively. For example, the discarding installation to this end can have a further transportation installation, for example a conveyor belt, onto which the remainders of the packaging are placed and by which the remainders of packaging are transported away from the severing device  108 . 
     The transportation installation can be configured for transporting the unpacked object  14  from the severing device  108  into a cleanroom  124 . 
     By virtue of the special spatial requirements which can be traced back, for example, to limitations by and of the variable space requirements in industrial sheds, it can be advantageous for the transportation installation  18  to not be constructed in a linear manner but instead having deflection portions between the individual devices, the folding-out device  60 , the stretching device  10 , and/or the severing device  108 , and upstream of the folding-out device  60  and downstream of the severing device  108 , said deflection portions causing a directional change of the transportation direction  20 . 
     The transportation installation  18  herein, in particular upstream of the folding-out device  60 , can have a first deflection portion  104  which causes a first directional change  106  of the transportation direction  20 , in particular wherein the first directional change  106  is 90°. 
     The transportation installation  18  can have a second deflection portion  110  between the stretching device  10  and the severing device  108  which causes a second directional change  112  of the transportation direction  20 , in particular wherein the second directional change  112  is 90°. 
     The transportation installation  18 , upstream of, in, or downstream of the severing device  108  can have a third deflection portion  114  which causes a third directional change  116  of the transportation direction  20 , in particular wherein the third directional change  116  is 90°. 
     In one alternative design embodiment of the unpacking system it can be provided that the unpacking system has a folding-out device  60 ″ as described in  FIGS. 14A to 18C , a stretching device  10  as described in  FIGS. 1A to 5D , and a severing device  108  which is identical to the severing device  108  of the unpacking system  100  described in  FIG. 11 . 
     However, the folding-out device  60 ″ does not have any lifting installation, and the stretching device  10  does not have any motion installation. Instead, the item of packaging is continuously transported downstream in the transportation direction  20  on the transportation installation  18 . 
     The unpacking system has a support holder  103  which configures the detent installation  92  of the folding-out device  60 ″ and the holding installation  24  of the stretching device  10 . The roller  94 ′ of the detent installation  92  thus corresponds to the roller  26 ″ of the holding device  24 , and the roller  94 ″ of the detent installation  92  corresponds to the roller  26 ″ of the holding device  24 . 
     Such an arrangement of an unpacking system requires that the packaging portion  16  is disposed on the end side of the item of packaging  12  that lies upstream, and from there extends on to one of the longitudinal sides which either faces of faces away from the transportation installation. The rollers  26 ′,  26 ″, or  94 ′,  94 ″, respectively, are furthermore configured so as to be movable relative to one another, in order for the rollers to be mutually spaced apart so far that the item of packaging  12  can be transported through between the rollers and for one of the rollers to be able to form a detent for the folded-in packaging portion, on the one hand, and in order for the packaging portion  16  to be clamped and held therebetween, on the other hand. 
     The functional mode of the alternative unpacking system will be described hereunder. 
     The object  14  is transported downstream in the transportation direction  20  on the transportation installation  18 . The rollers  26 ′,  26 ″, or  94 ′,  94 ″, respectively, are mutually spaced apart so far that the item of packaging  12  can be guided through between the rollers  26 ′,  26 ″, or  94 ′,  94 ″, respectively. The rollers  26 ′,  26 ″, or  94 ′,  94 ″, respectively, are brought to bear on the longitudinal side  30 ′,  30 ″ that faces and faces away from the transportation installation  18 . On account thereof, one of the rollers forms a detent for the folded-in packaging portion  16 . The transportation installation  18  transports the object  12  onwards, on account of which the packaging portion  16  is pushed on to one of the rollers which forms the detent. The packaging portion  16  is folded outwards on account thereof. The rollers in this instance are moved relative to one another in order for the packaging portion  16  to be clamped and held, on account of which the packaging portion  16  is stretched. 
     The alternative unpacking system preferably has a clamping device which is configured so as to be movable parallel with as well as perpendicularly to the transportation direction. The clamping installation is disposed downstream behind the support holder  103  which configures the detent installation  92  and the holding installation  24 . The clamping device therebetween jams the item of packaging  12  and the object  14  after said object  14  has partially passed the rollers. In order for the object  14  and the item of packaging  12  on account thereof not to be stopped or to be only briefly stopped, the clamping device after clamping moves conjointly with the object downstream in the transportation direction  20  at a speed which corresponds to the conveying speed of the transportation installation  18 . The folding outwards and stretching is improved on a account thereof. 
       FIG. 12A  shows a first embodiment of a method  200 ′ for unpacking an object  14 , in particular a pharmaceutical or cosmetic object, from an item of packaging  12 , in particular a pouch. The object  14  is transported in a transportation direction  20  on a transportation installation  18 . A packaging portion  16  of the item of packaging  12  initially is folded inwards between the transportation installation  18  and the item of packaging  12 . 
     In a step  202 , the packaging portion  16  is folded outwards by means of the method  180  which is described in  FIGS. 9 and 10   a  to  10   c . 
     The method  180  herein can be carried out either by the embodiment of a method for folding outwards  180 ′ described in  FIG. 9 , or by the embodiment of a method for folding outwards  180 ″ described in  FIG. 17 . 
     In a further step  204 , the projecting packaging portion  16  is stretched by means of the method  160  which is described in  FIGS. 4 and 5   a  to  5   d . 
     In a further step  206 , the projecting packaging portion  16  is severed. 
     In a further step  208 , the object  14  is retrieved from the opened item of packaging  12 . 
     The individual steps  202  to  208  of the method  200 ′ for unpacking are preferably carried out in succession. 
       FIG. 12  B shows a second embodiment of a method  200 ″ for unpacking an object  14 , in particular a pharmaceutical or cosmetic object, from an item of packaging  12 , in particular a pouch. The object  14  is transported in a transportation direction  20  on a transportation installation  18 . A packaging portion  16  of the item of packaging  12  initially is folded inwards between the transportation installation  18  and the item of packaging  12 . The individual method steps will be described in more detail hereunder. 
     In a step  210 , the object  14  is transported inwards on the transportation installation  18 .

       FIGS. 14A, 14B, 15, and 15  show an embodiment of a folding-out device  60 ″. The folding-out device  60 ″ is configured for folding outwards a folded-in packaging portion  16  of an item of packaging  12 . An object  14  is packed in the item of packaging  12 . The folding-out device  60 ″ has a transportation installation  18 , a lifting installation  62 , and a detent installation  92 . 
     The transportation installation  18  is configured for transporting the object  14  in a transportation direction  20 . The item of packaging  12  in relation to the transportation direction  20  has an upstream end side  28 ″ and a downstream end side  28 ′. The item of packaging  12  in relation to the transportation direction  20  furthermore has four longitudinal sides  30 ′,  30 ″,  30 ′″, and  30 ″″. A longitudinal side  30 ′ that faces the transportation installation  18  herein faces the transportation installation and is at least partially in contact with the transportation installation  18 . The item of packaging  12  by way of the longitudinal side  30 ′ that faces the transportation installation  18  accordingly bears on the transportation installation  18 . An upper longitudinal side  30 ′″ faces away from the transportation installation  18 . Two lateral longitudinal sides  30 ″ and  30 ″″ are disposed laterally to the transportation installation  18  and lie so as to be substantially perpendicular on the transportation installation  18 . 
     The packaging portion  16  is connected to the remainder of the item of packaging  12  on the downstream end side  28 ′ of the item of packaging  12 . The packaging portion  16  initially extends along the downstream end side  28 ′ in the direction of the longitudinal side  30 ′ of the item of packaging  12  that faces the transportation installation  18  and further in part along the longitudinal side  30 ′ of the item of packaging  12  that faces the transportation installation  18 . The packaging portion  16  is thus partially disposed between the longitudinal side  30 ′ of the item of packaging  12  that faces the transportation installation  18  and the transportation installation  18 . The packaging portion  16  is thus initially folded inwards between the transportation installation  18  and the longitudinal side  30 ′ of the item of packaging  12  that faces the transportation installation  18 . 
     Alternatively, the packaging portion  16  can initially extend along the downstream end side  28 ′ in the direction of the longitudinal side  30 ″ of the item of packaging  12  that faces away from the transportation installation  18  and further in part along the longitudinal side  30 ′″ of the item of packaging  12  that faces away from the transport installation  18 . The packaging portion  16  is thus folded inwards onto the longitudinal side  30 ′″ of the item of packaging  12  that faces away from the transportation installation  18 . 
     The transportation installation  18  has a transportation plane  38  on which the object  14  and the item of packaging  12  are transported. The transportation installation  18  furthermore has clearances  40  on the two peripheries of the transportation plane  38  such that the item of packaging  12  and the object  14  bear on the transportation installation  18  and the transportation plane  38  only in a central region. 
     The lifting installation  62  is configured for raising the object  14  conjointly with the item of packaging  12 . To this end, the lifting installation  62  has a vertical drive  76  for vertically moving the object perpendicularly to the transportation plane  38 . The lifting installation  62  in the embodiment illustrated furthermore has a clamping installation  74  which is configured for therebetween jamming the item of packaging  12  and the object  14 . The clamping installation  74  to this end has lifting elements  78 ′,  78 ″, and a detent element  80 . The lifting elements  78 ′,  78 ″ are disposed such that said lifting elements  78 ′,  78 ″ in a vertical movement perpendicular to the transportation plane  78  are moved through the two clearances  40  of the transportation plane  38 . The lifting elements  78 ′,  78 ″ have a contact face  82  which comes into contact with the longitudinal side  30 ′ of the item of packaging  12  that faces the transportation installation  18 . The contact face  82  herein, in particular in an upstream region of the longitudinal side  30 ′ that faces the transportation installation  18  comes to bear on the longitudinal side  30 ′ that faces the transportation installation  18 . The vertical drive  76  is configured for moving the lifting elements  78 ′,  78 ″ perpendicularly to the transportation plane  38 . The object  14  conjointly with the item of packaging  12  is thus movable perpendicularly to the transportation plane  38 . The detent element  80  has a bearing face  84  on which the item of packaging  12  by way of the longitudinal side  30 ′″ that faces away from the transportation installation  18  comes to bear when clamped. The bearing face  84  herein comes to bear on the longitudinal side  30 ′″ that faces away from the transportation installation  18  in particular in an upstream region of the longitudinal side  30 ′″ that faces away from the transportation installation  18 . On account thereof, the item of packaging  12  and the object  14  are held between the lifting elements  78 ′,  78 ″, and the detent element  80 . The lifting installation  62  furthermore has a frame  86  which includes the detent element  80  and connects the detent element  80  to the remaining components of the lifting installation  62 , said remaining components largely being disposed on that side of the transportation installation  18  that faces away from the item of packaging  12 . The frame  86 , proceeding from the transportation plane  38 , has a height  87 ′ which is greater than a height  13 ′ of the item of packaging  12 . On account thereof, it can be avoided that the item of packaging  12  when transported on the transportation plane  38  comes into contact with the detent element  80 , in particular scrapes along the latter or catches on the latter. Contact between the item of packaging  12  and the detent element  80  can be established only when the item of packaging  12  by way of the lifting elements  78 ′,  78 ″ is moved vertically away from the transportation plane  38  and comes to bear on the detent element  80 . The frame  86  furthermore has a width  57 ″ which is greater than a width  13 ″ of the item of packaging  12  and is greater than a width  19  of the transportation installation  18 . It can be avoided on account thereof that the item of packaging  12  when transported laterally comes into contact with the frame  86 , in particular scrapes along the latter or catches on the latter. 
     The detent installation  92  is configured for forming a detent for the packaging portion  16 . The detent installation  92  to this end has two rollers  94 ′,  94 ″, wherein a first roller  94 ′ of the rollers  94 ′,  94 ″ is disposed on the longitudinal side  30 ′ of the item of packaging  12  that faces the transportation installation  18 , and a second roller  94 ″ of the rollers  94 ′,  94 ″ is disposed on the longitudinal side  30 ′″ of the item of packaging  12  that faces away from the transportation installation  18 . Depending on which of the longitudinal sides the packaging portion is disposed, either the first or the second roller  94 ′,  94 ″ forms a detent for the folded-in packaging portion  16 . The detent installation  92  furthermore has a translatory roller drive installation  96  which can move the rollers  94 ′,  94 ″ relative to one another and perpendicularly to the transportation direction  20 . 
     Alternatively, the detent installation  92  can have only one roller  94 . The roller  94  is disposed on that longitudinal side  30 ′,  30 ′″ onto which the packaging portion  16  is folded inwards. 
       FIG. 17  shows a further embodiment of a method  180 ″ for folding outwards a packaging part  16  of an item of packaging  12 , in particular a pouch, for an object  14 , in particular pharmaceutical or cosmetic object. The folding-out device  60 ′ which is described in  FIGS. 14A to 16  is in particular suitable for carrying out the method  180 ″ for folding outwards. The object  14  herein is transported in a transportation direction  20  on a transportation installation  18 . 
     The packaging portion  16  can initially be folded inwards between the transportation installation  18  and the item of packaging  12 , in particular a longitudinal side  30 ′ of the item of packaging  12  that faces the transportation installation  18 . Alternatively, the packaging portion  16  initially can also be folded inwards onto the longitudinal side  30 ′″ of the item of packaging  12  that faces away from the transportation installation  18 . The individual method steps will be described in more detail hereunder. 
     In a first step  182 , the object  14  is raised from the transportation installation  18  by a lifting installation  62 . The lifting installation  62  herein on that side of the item of packaging that faces away from the transportation installation  18  can have a detent element  80  against which the item of packaging  12  and the object  14  in the raising  182  of the object  14  are pushed. The lifting installation  62 , on account thereof, is in particular configured for raising and holding the item of packaging  12  and the object  14 . 
     The lifting installation  62  in the step of raising  182  preferably holds the item of packaging  12  on at least one lateral face  30 ′,  30 ″,  30 ′″,  30 ″″. 
     Alternatively or additionally, the lifting installation  62  in the first step  182  can also raise the transportation installation  18 , in particular the transportation plane  38  of the transportation installation  18 , at least in the bearing region of the item of packaging  12  on the transportation plane  38 . 
     In a second step  188 , the lifting installation  62  and the detent installation  92  are moved relative to one another parallel with the transportation direction  20  in such a manner that the item of packaging  12  at least in portions is disposed on the detent installation  92 , wherein a roller  94  of the detent installation  92  is disposed on a longitudinal side  30 ′,  30 ′″ of the item of packaging  12  in order for a detent for the packaging portion  16  to be formed. 
     The roller  94  prior to the step of moving  188  is preferably disposed such that the item of packaging  12  can at least partially pass the roller  94 . 
     The roller  94  prior to the step of moving  188  is preferably disposed such that the roller  94  after the relative movement  188  bears on the longitudinal side of the item of packaging  12  on which the packaging portion  16  is folded inwards and forms a detent for the folded-in packaging portion  16 . 
     Alternatively, the roller can also be disposed such that the roller  94  after the relative movement  188  is disposed on that side of the item of packaging  12  on which the packaging portion  16  is folded inwards and is not in contact with the item of packaging  12 . The detent installation  92  can have a drive installation which moves the roller  94  perpendicularly to the transportation direction  20  and conveys the roller  94  so as to be in contact with the item of packaging and in this instance forms a detent for the folded-in packaging portion  16 . 
     Additionally or alternatively, the detent installation  92  can have two rollers  94 ′,  94 ″, wherein a first roller  94 ′ of the rollers  94 ′,  94 ″ is disposed on the longitudinal side  30 ′ of the item of packaging  12  that faces the transportation installation  18 , and a second roller  94 ″ of the rollers  94 ′,  94 ″ is disposed on the longitudinal side  30 ′″ of the item of packaging  12  that faces away from the transportation installation  18 . 
     In this case, the rollers  94 ′,  94 ″ prior to the step of moving  188  are disposed such that the spacing between the rollers  94 ′,  94 ″ is so large that the item of packaging  12  can be moved relative to the rollers  94 ′,  94 ″ and through the latter. That roller of the rollers  94 ′,  94 ″ that is disposed on the longitudinal side onto which the packaging portion  16  is folded inwards is disposed such that said roller forms a detent for the packaging portion  16 . 
     In a third step  190  the lifting installation  62  and the detent installation  92  are moved relative to one another parallel with the transportation direction  20  in such a manner that the folded-in packaging portion  16  is folded outwards. The folded-in packaging part  16  herein by means of the roller is pushed along the longitudinal side on which the packaging portion is disposed and, on account thereof, is folded outwards. 
       FIGS. 18A to 18C  show an isometric illustration of the individual method steps of the method  180 ″ for folding outwards the packaging portion  16 , said method  180 ″ being described in  FIG. 17 . 
       FIG. 18A  shows the step of raising  182 , in which the lifting installation  62  is disposed on that side of the object  14  that faces the transportation installation  18  and on account of a movement perpendicular to the transportation plane  38  is configured for raising the object  14  and the item of packaging  12 . In one advantageous design embodiment the longitudinal side  30 ′″ that herein faces away from the transportation installation  18  is pushed against a detent element  80 . The detent element  80  herein comes into contact with an upstream region of the longitudinal side  30 ′″ that faces away from the transportation installation  18 . On account of the lifting installation  64  pushing the object  14  and the item of packaging  12  against the detent element  80 , the object  14  and the item of packaging  12  are clamped and held on account thereof. 
       FIG. 18B  shows an isometric illustration of the step of the first relative movement  188 , in which the object  14  and the item of packaging  12  are moved through between the rollers  94 ′,  94 ″ so far until the rollers  94 ′,  94 ″ are disposed upstream of the packaging portion  16 . The object herein by means of the lifting installation is moved downstream in the transportation direction  20 . Prior to this step, the rollers  94 ′,  94 ″ are mutually spaced apart so far that the item of packaging  12  can be guided through between the rollers  94 ′,  94 ″. After the step of relative movement  188  the rollers  94 ′,  94 ″ downstream of the packaging portion  16  bear on the item of packaging  12 , wherein the first roller  94 ′ bears on the longitudinal side  30 ′ that faces the transportation installation, and the second roller  94 ″ bears on the longitudinal side  30 ′″ that faces away from the transportation installation. The roller  94 ′ forms a detent for the packaging portion  16 . 
       FIG. 18C  shows an isometric illustration of the step of the second relative movement  190 , in which the object  14  and the item of packaging  12  are moved parallel with the transportation direction  20  such that the packaging portion  16  is moved against the roller  94 ″, comes to bear on the roller  94 ″, and on account of the object  14  and the item of packaging  12  being moved onwards is folded outwards in this direction. To this end, the object in the example of  FIG. 18C  by means of the lifting installation is moved upstream counter to the transportation direction  20 . After the folding outwards, the rollers  94 ′,  94 ″ can optionally be moved relative to one another such that said rollers  94 ′,  94 ″ clamp the folded-out packaging portion. The packaging portion  16  in this instance can be stretched in a manner analogous to the embodiments of the stretching device  10  and to the method  160  for stretching from  FIGS. 1A to 5D . It can be provided in particular that the detent installation  92  of the folding-out device  60 ″ is identical to the holding installation  24  of the stretching device  10 , and the rollers  94 ′,  94 ″ are identical to the rollers  26 ″,  26 ′.
