     FIELD OF THE INVENTION 
     The present invention relates to an application unit with a positioning device and a magazine. The application unit includes at least one application mechanism which has at least one impression cylinder, at least one forme cylinder, and at least one supply roller, along with at least one positioning device. A supply position is a position that, during an application process of the application mechanism, is occupied by the at least one supply roller located in the application mechanism. The positioning device has at least one linear guide. The application unit has at least one magazine, which may be located below the application mechanism, for the storing of supply rollers. The magazine has at least two magazine receptacles, each for receiving one supply ruler. The magazine has at least one movable repositioning device, by the use of which the at least two magazine receptacles can be moved and placed in different magazine positions. 
     BACKGROUND OF THE INVENTION 
     In flexographic printing units, anilox rollers and forme cylinders with replaceable packings are typically used. The properties of the circumferential surface of the anilox roller have considerable influence on the amount of coating medium or application fluid that is transferred. It is therefore common for the anilox roller that is used to be based on the specific print job. Various devices for installing, removing, or replacing anilox rollers are known. 
     From DE 20 2005 006 367 U1, an application unit with a magazine for supply rollers is known. Supply rollers are removed laterally from a storage device, lowered by means of a transport lift, and then placed in the magazine, again laterally. 
     Known from U.S. Pat. No. 6,718,876 B1 is an application unit in which a forme cylinder and a supply roller are mounted on a common threaded spindle and can be lowered together by the rotation of said spindle. 
     Known from DE 198 05 898 A1 is an application unit in which different cylinders each have their own spindle drives. 
     From DE 199 37 796 A1 an application unit is known in which a stationary threaded spindle is provided, on which respective cylinders can be supported via their own drives and respective drive gears. 
     From DE 10 2008 016 598 A1 an application unit is known, which has a magazine for supply rollers, arranged above a printing mechanism. 
     From DE 10 2007 003 975 A1, an application unit having a printing mechanism is known, in which a magazine with four magazine receptacles can be located above the printing mechanism, and rollers can be replaced by means of a crane between the printing mechanism and the magazine spaces. 
     DE 10 2005 024 502 A1 discloses a flexographic printing unit with replaceable anilox rollers. One exemplary embodiment has a positioning device with linear guidance. Another exemplary embodiment has a magazine with a movable repositioning device and multiple magazine receptacles, which can be arranged in different magazine positions. 
     From EP 1 767 362 A2, a flexographic printing mechanism is known, which has a roller storage area and a positioning device with pivotable and telescopically extendable actuating devices, by means of which anilox rollers can be removed upward from the printing mechanism and fed to the roller storage area. 
     DE 199 62 425 A1 discloses a flexographic printing unit in which anilox rollers can be raised by means of a linearly movable component of a handling apparatus. To move the roller to a storage position, a further linear movement in a direction oriented orthogonally thereto or an additional pivoting movement must be carried out. 
     From DE 691 22 688 T2 a flexographic printing unit is known, in which three anilox rollers are arranged in a pivotable frame and can thus be brought alternatingly into contact with a forme cylinder. 
     DE 198 48 773 A1 discloses a flexographic printing press with multiple printing units, a guideway being arranged in each of the printing units, on which both printing roller bearing blocks and anilox roller bearing blocks can be moved. Levers, which are used to fix removable chamber doctor blades in place, are pivotably connected to the anilox roller bearing blocks. These levers can be moved in relation to the guideway only together with the anilox roller bearing blocks.

     From DE 44 13 807 C1 an application unit is known, which has a device for lifting out anilox rollers and forme cylinders from a magazine located above the application mechanism. In addition to the lifting-out device, carriages are provided, by means of which the anilox rollers and forme cylinders can be moved away from one another and from impression cylinders, to bring them into suitable positions for the devices to lift them out. 
     DE 694 00 025 T2 and EP 1 005 982 A1 each disclose an application unit in which an anilox roller is moved upward into a storage area and then sideways into one of multiple magazine receptacles.

     The object is attained according to the invention in that by the use of the at least one positioning device, at least one supply roller can be moved along a linear roller positioning path, one end of which is identical to the supply position and the other end of which is identical to a magazine position of the magazine positions of the at least one magazine that is configured as a change position. The positioning device has at least one transfer supporting member. The at least one transfer supporting member is arranged to be movable in and counter to a positioning direction relative to the frame of the flexographic application mechanism, guided by the at least one linear guide.

Alternatively or additionally, the application unit is preferably characterized in that the reservoir supporting member is arranged at least partially between the at least one main supporting member and the at least one transfer supporting member, as viewed in the positioning direction. This enables the corresponding application fluid reservoir to be moved, at least without great additional effort, relative to the forme cylinder, in particular together with the supply roller, and if necessary, enables the supply roller to still be moved away along the same guide over a greater distance and thereby also distanced from the application fluid reservoir. This, in particular, enables a particularly simple changing of the supply roller. 
     Alternatively or additionally, the application unit is preferably characterized in that the at least one forme cylinder is configured as a flexographic forme cylinder, and/or in that the at least one supply roller is configured as an anilox roller, and/or in that the at least one intermediate reservoir is configured as a chamber doctor blade system, and/or in that the at least one forme cylinder is located below the at least one impression cylinder, and/or in that a magazine receptacle is understood as a defined spatial area that is intended to accommodate one supply roller.

Alternatively or additionally, the application unit is preferably characterized in that the at least one reservoir supporting member is arranged to be movable linearly relative to the main supporting member closest to it, and in that the at least one reservoir supporting member is connected to said main supporting member via a suspension mount. This suspension mount preferably permits a limited relative movement, oriented in and/or counter to the positioning direction, between the main supporting member, on the one hand, and the reservoir supporting member, on the other hand. 
     Alternatively or additionally, the application unit is preferably characterized in that the positioning device has at least one thrust stop, in particular adjustable, which is provided as a contact element for contact between the at least one transfer supporting member, on the one hand, and the at least one reservoir supporting member, on the other. In that case, no additional drive for movement of the reservoir supporting member needs to be provided. 
     The application unit has at least one magazine for storing supply rollers. The at least one magazine is preferably located below the application mechanism. The magazine has at least two magazine receptacles, each for receiving one supply roller. The magazine further preferably has at least three and/or at least four magazine receptacles, each for receiving one supply roller, and/or a magazine receptacle is understood as a defined spatial area that is intended to receive one supply roller.

     The at least one supply roller can be moved by means of the at least one transfer supporting member along an exclusively linear roller positioning path. By means of the at least one positioning device, the at least one supply roller can be moved along the exclusively linear roller positioning path, one end of which is identical to a supply position and the other end of which is identical to one of the magazine positions. This first magazine position, in particular, is a change position. The roller positioning path preferably extends in and/or counter to the positioning direction. Alternatively or additionally, the application unit is preferably characterized in that, when a magazine receptacle is located in the change position, a supply roller can be transferred, in or counter to a positioning direction, between said magazine receptacle, on the one hand, and a region of the roller positioning path that is remote from said magazine, on the other hand, said positioning path connecting the magazine to the application mechanism. This feature, in particular, preferably results in a particularly simple and/or rapid roller positioning path and/or a particularly simple device that is less prone to error.

The repositioning device and the inner boundary surface are preferably arranged to be movable relative to the outer boundary surface. In this way, safe handling of the supply rollers in the magazine can be achieved with a minimum expenditure on apparatus. 
     Alternatively or additionally, the application unit is preferably characterized in that the magazine has at least one outer boundary member, which is arranged stationary, in particular relative to the frame of the application unit, and in that the at least one outer boundary surface is a surface of the at least one outer boundary member.

     DESCRIPTION OF PREFERRED EMBODIMENTS 
     In the foregoing and in the following, the term coating medium or printing fluid or application fluid refers to inks and printing inks, but also to primers, varnishes, and pasty materials. Printing fluids are preferably materials that are and/or can be transferred by means of a processing machine  01 , in particular a printing press  01 , or by means of at least one application mechanism  414 ;  614 ;  814  or application unit  400 ;  600 ;  800  of the processing machine  01 , in particular at least one printing mechanism  614  or printing unit  600  of the printing press  01 , onto a substrate  02 , in particular a printing material  02 , thereby creating a preferably visible and/or perceptible and/or machine detectable texture, preferably in finely structured form and/or not merely over a large surface area, on the substrate  02 , in particular printing material  02 . Inks and printing inks are preferably solutions or dispersions of at least one colorant in at least one solvent. Suitable solvents include water and/or organic solvents, for example. Alternatively or additionally, the printing fluid can be embodied as printing fluid that is cured under UV light. Inks are relatively low-viscosity printing fluids and printing inks are relatively high-viscosity printing fluids. Inks preferably contain no binding agent or relatively little binding agent, whereas printing inks preferably contain a relatively large amount of binding agent, and more preferably contain additional auxiliary substances. Colorants may be pigments and/or dyes, with pigments being insoluble in the application medium, whereas dyes are soluble in the application medium. 
     In the interest of simplicity, in the foregoing and in the following—unless otherwise explicitly distinguished and specified—the term “printing ink” is understood to refer to a liquid or at least flowable fluid colorant to be used for printing in the printing press, and is not limited merely to the higher viscosity fluid colorants more frequently associated colloquially with the expression “printing ink” for use in rotary printing presses, but in addition to these higher viscosity fluid colorants particularly also includes lower viscosity fluid colorants such as “inks”, in particular inkjet inks, but also powdered fluid colorants, such as toners, for example. Thus in the foregoing and in the following, when printing fluids and/or inks and/or printing inks are mentioned, this also includes colorless varnishes. In the foregoing and in the following, when printing fluids and/or inks and/or printing inks are mentioned, this also preferably includes, in particular, agents for pretreating (priming or pre-coating) the printing material  02 . The term coating medium and the term application fluid may be understood as synonymous with the term printing fluid. 
     An application fluid preferably is not gaseous. An application fluid is preferably liquid and/or powdered. 
     A processing machine  01  is preferably configured as a printing press  01  and/or as a shaping machine  01 , in particular a die-cutting machine  01 . The printing press  01  is configured as a flexographic printing press  01 , for example. 
     The processing machine  01  is preferably referred to as a printing press  01  if it comprises at least one printing mechanism  614  and/or at least one printing unit  600 , in particular regardless of whether it comprises additional units for processing substrate  02 . A processing machine  01  configured as a printing press  01  also comprises, for example, at least one additional such unit  400 ;  800 ;  900 , for example at least one shaping unit  900 , which is preferably configured as a die-cutting unit  900 . The processing machine  01  is preferably referred to as a shaping machine  01  if it comprises at least one shaping mechanism  914  and/or at least one shaping unit  900 , in particular regardless of whether it comprises additional units  400 ;  600 ;  800  for processing substrate  02 . The processing machine  01  is preferably referred to as a die-cutting machine  01  if it comprises at least one die-cutting mechanism  914  and/or at least one die-cutting unit  900 , in particular regardless of whether it comprises additional units  400 ;  600 ;  800  for processing substrate  02 . A processing machine  01  configured as a shaping machine  01  or die-cutting machine  01  also comprises, for example, at least one additional unit  400 ;  600 ;  800  for processing substrate  02 , for example at least one printing unit  600  and/or at least one printing mechanism  614 . Thus, if the processing machine  01  comprises at least one printing mechanism  614  and/or at least one printing unit  600  and also comprises at least one shaping mechanism  914  and/or at least one shaping unit  900 , it is configured both as a printing press  01  and as a shaping machine  01 . If the processing machine  01  comprises at least one printing mechanism  614  and/or at least one printing unit  600  and also comprises at least one die-cutting mechanism  614  and/or at least one die-cutting unit  900 , it is therefore configured both as a printing press  01  and as a shaping machine  01 , in particular a die-cutting machine  01 . 
     The processing machine  01  is preferably configured as a sheet processing machine  01 , i.e. as a processing machine  01  for processing sheet-format substrate  02  or sheets  02 , in particular a sheet-format printing material  02 . For example, the sheet processing machine  01  is configured as a sheet-fed printing press  01  and/or as a sheet-fed shaping machine  01  and/or as a sheet-fed die-cutting machine  01 . The processing machine  01  is further preferably configured as a corrugated cardboard sheet processing machine  01 , i.e. as a processing machine  01  for processing sheet-format substrate  02  or sheets  02  of corrugated cardboard, in particular sheet-format printing substrate  02  made of corrugated cardboard. More preferably, the processing machine  01  is configured as a sheet-fed printing press  01 , in particular as a corrugated cardboard sheet-fed printing press  01 , i.e. as a printing press  01  for coating and/or printing sheet-format substrate  02  or sheets  02  of corrugated cardboard, in particular sheet-format printing material  02  made of corrugated cardboard. For example, printing press  01  is configured as a printing press  01  that operates according to a non-impact printing method and/or as a printing press  01  that operates according to a printing method that requires printing formes. Preferably, printing press  01  is configured as a non-impact printing press  01 , in particular as an inkjet printing press  01  and/or as a flexographic printing press  01 . Alternatively or additionally, the processing machine  01  may be configured as a web-fed processing machine  01 , in particular a web-fed printing press  01 , provided no contradictions arise as a result. 
     Unless an explicit distinction is made, the term sheet-format substrate  02 , in particular printing material  02 , specifically sheet  02 , generally includes any flat substrate  02  in the form of sections, i.e. including substrates  02  in tabular form or panel form, i.e. including boards or panels. The sheet-format substrate  02  or sheet  02  thus defined is formed, for example, from paper or paperboard, i.e. as sheets of paper or paperboard, or as sheets  02 , boards, or optionally panels made of plastic, cardboard, glass, or metal. The substrate  02  is more preferably corrugated cardboard  02 , in particular corrugated cardboard sheets  02 . The thickness of a sheet  02  is preferably understood as the dimension orthogonally to the largest surface area of the sheet  02 . This largest surface area is also referred to as the main surface area. The thickness of the sheets  02  is, for example, at least 0.1 mm, more preferably at least 0.3 mm, and even more preferably at least 0.5 mm. For sheets of corrugated cardboard  02 , in particular, significantly greater thicknesses are also common, for example at least 4 mm or even 10 mm or more. Corrugated cardboard sheets  02  are relatively stable and therefore are not very flexible. Corresponding adjustments to the processing machine  01  therefore facilitate the processing of sheets  02  of great thickness.

     In one operating state of the application unit  400 ;  600 ;  800 , at least one rolling bearing  27  of a supply roller  403 ;  603 ;  803  is preferably arranged in a bearing seat  44  that is movable, in particular by means of the at least one transfer supporting member  19 , and the supply roller  403 ;  603 ;  803  is in contact with a forme cylinder  402 ;  602 ;  802  and/or the packing  04  thereof. In another operating state of the application unit  400 ;  600 ;  800 , said at least one rolling bearing  27  of said supply roller  403 ;  603 ;  803  is preferably arranged in said bearing seat  44 , which is movable, in particular, by means of the at least one transfer supporting member  19 , and said supply roller  403 ;  603 ;  803  is arranged in a magazine receptacle  22  of the magazine  21 . In yet another operating state of the application unit  400 ;  600 ;  800 , said at least one rolling bearing  27  of said supply roller  403 ;  603 ;  803  is out of contact with said bearing seat  44 , which is movable in particular by means of the at least one transfer supporting member  19 , and said supply roller  403 ;  603 ;  803  is arranged in said magazine receptacle  22  of the magazine  21 . 
     Alternatively or additionally, the application unit  400 ;  600 ;  800  is preferably characterized in that every bearing contact region of a supply roller  403 ;  603 ;  803 , with which the supply roller  403 ;  603 ;  803  is in contact with said bearing seat  44  of the application unit  400 ;  600 ;  800 , is located spaced apart with respect to a transverse direction A from every magazine contact region with which the supply roller  403 ;  603 ;  803  in a magazine receptacle  22  is in contact with the magazine  21 . The bearing contact region is preferably an outer ring of the at least one rolling bearing  27  and/or at least one component that is fixedly connected to such an outer ring. The magazine contact region is a part of a roller barrel  17  of the supply roller  403 ;  603 ;  803 , for example, but preferably is a part of a roller journal  18  of the supply roller  403 ;  603 ;  803 . 
     The at least one positioning device  43  preferably comprises the at least one linear guide  07  and/or the at least one main supporting member  06  and/or the at least one main gearbox  08  and/or the at least one transfer supporting member  19  and/or the at least one transfer drive M 6  and/or the at least one positioning drive M 4  and/or the at least one transfer gearing unit  54  and/or the at least one reservoir supporting member  57  and/or the at least one thrust stop  63  and/or the at least one reservoir positioning element  66 . 
     There are various relevant cases in which the chamber doctor blade system  401 ;  601 ;  801  will be moved. A first such case occurs when the flexographic application mechanism  414 ;  614 ;  814  needs to be adapted to a substrate  02  of a different thickness. In that case, the forme cylinder  402 ;  602 ;  802  is preferably moved relative to the impression cylinder  408 ;  608 ;  808  to set an appropriate distance. The supply roller  403 ;  603 ;  803  is also preferably moved to maintain or restore an appropriate contact with the forme cylinder  402 ;  602 ;  802 . Further, the chamber doctor blade system  401 ;  601 ;  801  is preferably moved together with the supply roller  403 ;  603 ;  803 , to prevent an unintentional leakage of application fluid and/or damage to the supply roller  403 ;  603 ;  803  and/or to the chamber doctor blade system  401 ;  601 ;  801 . Forme cylinder  402 ;  602 ;  802 , supply roller  403 ;  603 ;  803 , and chamber doctor blade system  401 ;  601 ;  801  are preferably moved jointly for this purpose. 
     A second such case occurs when a new packing  04  will be placed on the forme cylinder  402 ;  602 ;  802  and/or an old packing  04  will be removed from the forme cylinder  402 ;  602 ;  802 . In that case, the forme cylinder  402 ;  602 ;  802  is preferably moved relative to the impression cylinder  408 ;  608 ;  808 , for example by at least 15 cm and/or by at most 40 cm, in order to create sufficient space. Further, the supply roller  403 ;  603 ;  803  is preferably moved relative to the forme cylinder  402 ;  602 ;  802 , for example by at least 10 mm and/or by at most 30 mm, in order to create sufficient space. The chamber doctor blade system  401 ;  601 ;  801  is preferably moved together with the supply roller  403 ;  603 ;  803  to prevent any unintentional leakage of application fluid. (Such a positioning is also illustrated by way of example in  FIGS. 5 a  to 5 d   .) The application unit  400 ;  600 ;  800  has at least one safety device  73 , for example, which more preferably can be opened for the mounting and/or removal of a corresponding packing  04 , and otherwise protects operators from a risk of injury. 
     A third such case occurs when a supply roller  403 ;  603 ;  803  will be installed, changed, or removed. In that case, the chamber doctor blade system  401 ;  601 ;  801  preferably is first backed away from the supply roller  403 ;  603 ;  803 . Further, for example, the forme cylinder  402 ;  602 ;  802  is backed away from the impression cylinder  408 ;  608 ;  808 , for example by at least 10 cm and at most 40 cm. The supply roller  403 ;  603 ;  803  preferably likewise performs this movement, due to the configuration of the positioning device  43 . Afterward, the supply roller  403 ;  603 ;  803  is preferably moved further, for example into a magazine  21  of the application unit  400 ;  600 ;  800  or into a loading position. For this purpose, the supply roller  403 ;  603 ;  803  is moved downward by at least 400 mm and/or at most 600 mm, for example. (Corresponding positions are also illustrated by way of example in  FIGS. 6 a  to 6 e   .) The application unit  400 ;  600 ;  800  has at least one covering device  69 , for example, which further preferably can be opened to allow the transfer of a supply roller  403 ;  603 ;  803  between the application mechanism  414 ;  614 ;  814  and the magazine  21 , and otherwise protects the magazine  21  and/or the supply rollers  403 ;  603 ;  803  arranged therein from soiling. 
     The application unit  400 ;  600 ;  800  preferably comprises the at least one magazine  21  for storing supply rollers  403 ;  603 ;  803 . The at least one magazine  21  is preferably located below the application mechanism  414 ;  614 ;  814 , more preferably such that the axis of rotation  39  of the forme cylinder  402 ;  602 ;  802  is located above the magazine  21  in the vertical direction V, even more preferably such that the axis of rotation  39  of the forme cylinder  402 ;  602 ;  802  is located above the magazine axis  24  of the magazine  23  in the vertical direction V. The at least one magazine  21  preferably has at least two, more preferably at least three, even more preferably at least four, and more preferably still precisely four magazine receptacles  22 , each for accommodating one supply roller  403 ;  603 ;  803 . In this way, at least one supply roller  403 ;  603 ;  803  can always be held in reserve near its intended point of use in case a supply roller  403 ;  603 ;  803  currently in use might need to be replaced. Such a replacement typically occurs, for example, when a subsequent print job calls for a smaller or larger quantity of application fluid per unit of surface area. 
     A magazine receptacle  22  is understood here, in particular, as a defined spatial area that is intended to accommodate one supply roller  403 ;  603 ;  803  and preferably has the dimensions thereof. The respective magazine receptacle  22  is preferably defined by at least one boundary and/or at least one component and/or at least one surface and is preferably movable. Said boundary or said component or said surface does not need to fully enclose the corresponding spatial area. It is sufficient for bearing regions for roller journals  18  to be defined, for example, from which the position of the entire supply roller  403 ;  603 ;  803  then results. When the specific boundaries and/or components and/or surfaces that define the magazine receptacle  22  are at least partially moved, then the magazine receptacle  22  and particularly also any respective supply roller  403 ;  603 ;  803  that may be located in the magazine receptacle  22 , preferably also move along with these. 
     The magazine  21  preferably has at least one movable repositioning device  23 , by means of which the at least two magazine receptacles  22  can be moved and placed in different magazine positions  28 . A magazine position  28  in this context is understood, in particular, as a defined spatial area that is intended to accommodate one supply roller  403 ;  603 ;  803 . While a magazine receptacle  22  is defined at all times by the position of physical components of the magazine  21  and is therefore preferably movable, a respective magazine position  28  refers to a very specific position of a corresponding magazine receptacle  22 , in particular regardless of whether or not a magazine receptacle  22  or even a supply roller  403 ;  603 ;  803  is actually disposed in said position. A respective magazine position  28  is thus defined in space and is preferably stationary, in particular stationary with respect to the frame  427 ;  627 ;  827  of the flexographic application mechanism  414 ;  614 ;  814  and/or of the flexographic application unit  400 ;  600 ;  800 . 
     The at least one movable repositioning device  23  is preferably pivotable and/or rotatable about the magazine axis  24 . Two repositioning devices  23  are provided, for example, in particular spaced apart from one another in the transverse direction A, and are arranged to be pivotable and/or rotatable about a common magazine axis  24 . These two repositioning devices  23  are preferably connected to one another via a magazine shaft. The at least one repositioning device  23  is preferably arranged to be movable by means of at least one drive M 7 , also referred to as magazine drive M 7 , in particular in that the magazine drive M 7  effects a pivoting movement or rotational movement about the magazine axis  24 . The at least one magazine drive M 7  is preferably configured as a motor M 7 , more preferably as a closed loop position-controlled electric motor, in particular. 
     One example of such boundaries and/or components and/or surfaces that define the magazine receptacle  22  is at least one inner boundary surface  31  and/or at least one outer boundary surface  32 . Alternatively or additionally, the application unit  400 ;  600 ;  800  is preferably characterized in that magazine receptacles  22 , in particular at least all of such magazine receptacles  22  that are connected to the repositioning device  23 , are at least also defined by at least one respective movable inner boundary surface  31 , which in particular is movable relative to the frame  427 ;  627 ;  827  of the application unit  400 ;  600 ;  800  and which is intended for contact with a roller journal  18  or a roller barrel  17  of a respective supply roller  403 ;  603 ;  803 , said at least one inner boundary surface  31  preferably being configured as part of the repositioning device  23 . The respective inner boundary surface  31  is preferably concave and, when oriented appropriately, preferably forms a type of shell in which the roller journal  18  can be held, in particular against the force of gravity. The at least one inner boundary surface  31  is preferably a surface  31  of the repositioning device  23 . 
     Since the magazine receptacles  22  can preferably execute a circulating movement, as described above, situations also arise in which the inner boundary surface  31  is not sufficient to hold the supply roller  403 ;  603 ;  803  in the magazine receptacle  22  against the force of gravity. For that reason, the magazine receptacles  22  are configured as lockable, for example. This can be accomplished by means of a locking mechanism that circulates together with the magazine receptacle  22 . Preferably, however, the application unit  400 ;  600 ;  800  is characterized in that such magazine receptacles  22 , which are arranged in a magazine position  28  of a first subset of all possible magazine positions  28 , in addition to being defined by the at least one inner boundary surface  31 , are at least also defined by at least one respective fixedly arranged outer boundary surface  32 , configured for contact with a roller journal  18  or a roller barrel  17  of a respective supply roller  403 ;  603 ;  803 . The respective outer boundary surface  32  is preferably arranged stationary relative to the frame  427 ;  627 ;  827  of the application unit  400 ;  600 ;  800 , in particular relative to the frame  427 ;  627 ;  827 , relative to which the repositioning device  23  and the inner boundary surface  31  are movably arranged. 
     Preferably, the magazine  21  has at least one outer boundary member  68 . The at least one outer boundary member  68  is preferably arranged in a stationary manner, in particular stationary relative to the frame  427 ;  627 ;  827  of the application unit  400 ;  600 ;  800 . The at least one outer boundary surface  32  is preferably a surface  32  of the at least one outer boundary member  68 . The shape of the at least one outer boundary member  68  and/or of the at least one outer boundary surface  32  is preferably adapted to a movement path of the at least one repositioning device  23 . This preferably ensures that the magazine receptacles  22  are always closed sufficiently in the relevant regions to prevent supply rollers  403 ;  603 ;  803  from moving unintentionally or even falling out. The at least one repositioning device  23  preferably has a rotationally symmetrical contour. For example, the at least one repositioning device  23  is configured as a cylindrical disk with indentations on its outer surface. The boundary surfaces of these indentations are preferably the inner boundary surfaces  31 . Such a repositioning device  23  is preferably rotatably arranged. The magazine axis  24  preferably forms the center axis of this flat cylindrical disk. The cylindrical disk may have recesses for the purpose of weight reduction and may even be reduced to such an extent that it consists only of shells that comprise the inner boundary surfaces  31  and braces that connect these shells to a central supporting member. The at least one outer boundary member  68  preferably has at least a concave shape. More preferably, the outer boundary member  68  has a concave surface  32  in the form of a circular arc or a cylindrical shell segment, formed as the outer boundary surface  32 . The magazine axis  24  preferably forms the center axis of this outer boundary surface  32  in the form of a circular arc or a cylindrical shell segment. When the at least one repositioning device  23  rotates, corresponding magazine receptacles  22  are then preferably closed off by the outer boundary surface  32 , with the associated magazine positions  28  being defined by their position relative to the outer boundary member  68 . 
     In one embodiment, the at least one repositioning device  23  can be pivoted and/or rotated about the magazine axis  24 . The at least one repositioning device  23  preferably has at least two recesses, which form magazine receptacles  22 . These recesses are preferably identical in structure. The at least two recesses are preferably each open in a radial direction with respect to the magazine axis  24 . Each of the at least two recesses preferably has at least one inner boundary surface  31 , which defines the minimum distance between a supply roller  403 ;  603 ;  803  and the magazine axis  24 . Preferably, dimensions of each of the at least two recesses, each with respect to its radial direction, are greater than the diameter of the roller journals  27  at a respective point intended to be received in the respective magazine receptacle  22 . These dimensions of each of the at least two recesses, each with respect to its radial direction, are preferably less than twice the diameter of the roller journals  27  at this respective point. Dimensions of each of the at least two recesses, each with respect to its circumferential direction, are preferably greater than the diameter of the roller journals  27  at the respective point intended to be received in the respective magazine receptacle  22 . Preferably, these dimensions of each of the at least two recesses, each with respect to its circumferential direction, are less than twice the diameter of the roller journals  27  at this respective point, more preferably less than 110% of said diameter. 
     The at least one outer boundary surface  32  is preferably shaped such that its projection in the transverse direction A corresponds to a circular arc. The radius of said circular arc is preferably greater than the greatest distance of the repositioning device  23  from the magazine axis  24 . The radius of said circular arc is preferably no more than 20%, more preferably no more than 10%, and even more preferably no more than 5% greater than the greatest distance of the repositioning device  23  from the magazine axis  24 . The central angle of said circular arc is preferably at least 180°, more preferably at least 190°, and even more preferably at least 200°. A portion of said circular arc in which a respective normal vector has a component that points upward preferably extends over a central angle of at least 160°, more preferably at least 170°, and even more preferably at least 175°. In this way, every area in which there would otherwise be a risk of the supply roller  403 ;  603 ;  803  moving downward out of its magazine receptacle  22  can be covered. 
     The at least one outer boundary surface  32  is preferably covered with a material that has a relatively high coefficient of friction, for example rubber. Thus, when a roller journal  27  of a supply roller  403 ;  603 ;  803  is in contact with this outer boundary surface  32  while the repositioning device  23  is being rotated, the corresponding supply roller  403 ;  603 ;  803  is preferably set in a rolling motion along the outer boundary surface  32 , in addition to its circulating movement in the circumferential direction. This rolling motion can be utilized, for example, by placing a cleaning device, for example a brush, in contact with a cylindrical roller surface of the supply roller  403 ;  603 ;  803 . The supply roller  403 ;  603 ;  803  is then cleaned as it is being repositioned. A contact region intended for contact between supply roller  403 ;  603 ;  803  and cleaning device extends over an angular range of at least 45°, more preferably at least 90°, and even more preferably at least 110° around the magazine axis  24 , for example. 
     Alternatively or additionally, the application unit  400 ;  600 ;  800  is preferably characterized in that by means of the at least one positioning device  43 , at least one supply roller  403 ;  603 ;  803   603 ;  803  can be moved along an exclusively linear roller positioning path  33 , one end of which is identical to the supply position  29  and the other end of which is identical to a change position  34 . The change position  34  is preferably the specific magazine position  28 ;  34  in which a magazine receptacle  22  must be located in order for a direct changing of a supply roller  403 ;  603 ;  803  between the magazine  21 , on the one hand, and the application mechanism  414 ;  614 ;  814 , on the other hand, to be carried out. The roller positioning path  33  is preferably used in the movement of a supply roller  403 ;  603 ;  803 , to throw said roller onto a forme cylinder  402 ;  602 ;  802  and/or to throw it off of a forme cylinder  402 ;  602 ;  802 . The roller positioning path  33  preferably extends in and/or counter to the positioning direction B. The change position  34  is preferably the highest magazine position  28  a magazine receptacle  22  of the magazine  21  can occupy, and/or the magazine  21  is preferably located below the application mechanism  414 ;  614 ;  814 . 
     Alternatively or additionally, the application unit  400 ;  600 ;  800  is preferably characterized in that at least one of the magazine positions  28 , in particular the first, is the change position  34 . The change position  34  preferably serves as the starting point for an infeed of a supply roller  403 ;  603 ;  803  to the application mechanism  414 ;  614 ;  814  and/or as the end point and/or intermediate point for a removal of a supply roller  403 ;  603 ;  803  from the application mechanism  414 ;  614 ;  814 . Alternatively or additionally, the application unit  400 ;  600 ;  800  is preferably characterized in that, when a magazine receptacle  22  is located in the change position  34 , a supply roller  403 ;  603 ;  803  can be transferred, in or counter to the positioning direction B, between said magazine receptacle  22 , on the one hand, and a region of the roller positioning path  33  that is remote from said magazine  21 , on the other hand, said positioning path connecting the magazine  21  to the application mechanism  414 ;  614 ;  814 . For movements of supply rollers  403 ;  603 ;  803  between the change position  34  and the supply position  29 , the at least one positioning device  43 , in particular the at least one transfer supporting member  19 , is provided. For movements of supply rollers  403 ;  603 ;  803  between the change position  34  and other magazine positions  28 , the at least one repositioning device  23  is preferably provided. 
     Alternatively or additionally, the application unit  400 ;  600 ;  800  is preferably characterized in that at least one of the magazine positions  28 , in particular the second, is a loading position  36 . The loading position  36  preferably serves as the starting point for transporting a supply roller  403 ;  603 ;  803  away from the application unit  400 ;  600 ;  800  and therefore preferably acts as an unloading position. Alternatively or additionally, the application unit  400 ;  600 ;  800  is preferably characterized in that, when a magazine receptacle  22  is located in the loading position  36 , a supply roller  403 ;  603 ;  803  can be transferred along a loading path  37 , which is linear in particular, in or counter to a loading direction L between said magazine receptacle  22 , on the one hand, and a loading area  38 , on the other. The loading area  38  is preferably a loading area  38  of the application unit  400 ;  600 ;  800 . Alternatively or additionally, the application unit  400 ;  600 ;  800  is preferably characterized in that the loading path  37  is formed as a linear loading path  37  and/or in that the loading direction L deviates from at least one horizontal direction C by no more than 30°, more preferably no more than 20°, even more preferably no more than 10°, and more preferably still no more than 5°, or is oriented horizontally. This horizontal direction C is preferably oriented orthogonally to the transverse direction A and/or to the axis of rotation  39  of the forme cylinder  402 ;  602 ;  802 . The loading position  36  preferably also serves as the intake point for feeding a supply roller  403 ;  603 ;  803  into the application unit  400 ;  600 ;  800 , and therefore preferably acts as an uploading position. Supply rollers  403 ;  603 ;  803  are preferably moved, in particular rolled, for example manually or automatically, along the loading path  37 . 
     Supply rollers  403 ;  603 ;  803  are preferably moved between the loading position  36  and  23 . At least one delivery device  71  can be arranged in the loading area  38 , for example, for the purpose of exchanging supply rollers  403 ;  603 ;  803  between the magazine  21  and an area outside of the application unit  400 ;  600 ;  800 . A transport cart  71  may be used as such a delivery device  71 , for example. The application unit  400 ;  600 ;  800  preferably has at least one locking element  72 , which separates the loading area  38  from the loading position  36  when no exchange of supply rollers  403 ;  603 ;  803  between loading area  38  and loading position  36  is planned. Further preferably, the at least one locking element  72  then serves at least partially as an outer boundary surface  32 . The at least one locking element  72  can preferably be opened to enable an exchange of supply rollers  403 ;  603 ;  803  between loading area  38  and loading position  36 . Further preferably, the at least one locking element  72  then serves at least partially as a supporting surface and/or to define the loading path  37 . (For illustrative purposes only, one opened locking element and one closed locking element  72  are shown by way of example in each of  FIGS. 4 a  to 4 c   . Preferably, however, these locking elements  72  are always either both opened or both closed.)

The transport devices  700  are preferably configured as suction transport devices  700  for the suspended transport of the substrate  02 . The die-cutting device  900  preferably has a forme cylinder, which is arranged above an impression cylinder. (Such a processing machine  01  according to the first exemplary embodiment is also shown by way of example in  FIG. 1 .) 
     In a second exemplary embodiment of the processing machine  01 , the processing machine  01  comprises a substrate supply device  100 , an infeed device  300 , for example a pre-processing device, a flexographic application unit  400  configured as a primer device  400 , a non-impact printing device  600 , a flexographic application unit  800  configured as a varnishing device  800 , and a substrate delivery device  1000 .
