Abstract:
For the disposal of material webs, such as spent support films ( 13 ) of embossing objects ( 19 ) obtained from an embossing device ( 11 ), the material web (film) is introduced via a slip drive into a storage chamber, where it forms freely hanging or spontaneously deposited loops. The latter form a reservoir for a discontinuous or alternating operation of the embossing device. The loops ( 43 ) or packages can be individually cut off in the disposal device or at the storage chamber outlet can be rolled up so as to form rolls. The fill level in the storage device is at least sufficiently large that a retraction of the webs from the storage device is possible without influencing the web tension in the utilization area.

Description:
[0001]     The following disclosure is based on German Patent Application No. 102005003787.9 filed on Jan. 19, 2005, which is herewith incorporated into this application by explicit reference.  
       BACKGROUND OF THE INVENTION  
       [0002]     The invention relates to a method and a device for disposing of flexible material in the form of at least one moving material web supplied in a supply direction with a supply web speed from a utilization area of a disposal device. Such material webs to be disposed of arise more particularly behind the embossing gap of embossing devices to which an embossing foil or film web is supplied and which serves as a support for objects such as holograms, metal coatings, etc. In said embossing gap the objects are applied to a product, i.e. a paper web, a sheet or a cardboard packaging, usually by heat sealing. The support material web is left in the form of a film strip from which the objects are removed and which is now to be supplied for recycling or disposal. The standard method of winding or rolling up is subject to the problem that the film which has possibly been deformed by the heat sealing-embossing process may not be easily windable or rollable and also the roll has to be changed, which does not always coincide with a change to the unconsumed embossing film web, because frequently several embossing film webs with different consumption are passed in parallel through the embossing gap.  
         [0003]     As the objects are applied to the end product, e.g. the paper web, usually at considerable intervals, it would be uneconomic to arrange them with equal spacings on the embossing film web. The applicant has developed a method (DE 37 13 666 C and EP 718 099 B, corresponding to U.S. Pat. No. 6,519,821), through which said film economizing effect can be controlled despite the requirement of absolute synchronism between the embossing film web and the web to be printed in the embossing gap. This takes place through successive accelerating, synchronizing, decelerating and retracting phases for the embossing film web.  
         [0004]     To permit such discontinuous material web movements, in DE 198 42 585 A and the corresponding EP 987 205 B and U.S. Pat. No. 6,230,616 A, the embossing gap is followed by a slip drive which is in turn followed by a film storage device equipped with suction belts. The material web is then rolled up in the conventional manner.  
         [0005]     It is also known from EP 989 086 B to dispose of material web portions and a separating device cooperating with a conveying roller is provided. Upstream of the separating device can be provided a not described film storage device.  
       OBJECT OF THE INVENTION  
       [0006]     An object of the invention is to provide a method and a device for the disposal of flexible material, which does not impair a discontinuous conveying of material web and the uniformity of its tension and has no significant effects on the entering material web. A further object is to makes it possible to dispose of the material web in the size reduced state.  
       SUMMARY OF THE INVENTION  
       [0007]     According to a feature of the invention storage takes place in individual material web portions, preferably in the form of loops, which enter a storage device in a substantially freely hanging form and follow a separating cut where the material web is separated from the preceding material web portion. In place of a loop formation, it is also possible to form a package deposited freely in concertina-like form. By lateral movements either of the entering film or a holding device for the film end, the invention makes it possible to form a new loop or package during the separation of the preceding item. The material web portions can be stored in hanging loops, in each case formed solely by an outwardly travelling strand and a return travelling strand, or and which permits a greater storage capacity, can be stored in automatically, concertina-like packages, between which there is in each case a separation or which are as such directly or indirectly supplied for disposal.  
         [0008]     According to another feature of the invention the thus formed packages are e.g. formed on an enveloping medium, e.g. a packaging film or net, which is passed under the package and is conveyed away with the latter, so that there is a formation of continuous packages of concertina-like, ragged material web portions. It is possible to roll up the same, e.g. together with the enveloping medium. In order to permit a “continuous” disposal, said rolling up can take place under an angle to the conveying in direction of the packages, so that a sloping or helical roll is formed, which “grows out” on one side of the roll and can be cut to length there as individual pieces.  
         [0009]     It is also possible to operate without an enveloping material placed under the package, if the storage chambers in which the packages are formed are constructed in such a way, e.g. bevelled with respect to the horizontal, that the packages of their own accord slide or are drawn towards the storage chamber outlet. At this point, e.g. by a packing or stuffing winder and by a corresponding inclined positioning, a roll (“sausage”) could be formed which passes out of the optionally conical stuffing winder and can be enclosed there by an enveloping band before a cutting to length takes place.  
         [0010]     It is clear that this leads to a minimization of the problem arising when the spent material web is merely rolled up and which results from the fact that in an embossing machine frequently numerous different and also differently wide material webs run in parallel and also arrive at different supply web speeds.  
         [0011]     In the case of the invention it is merely necessary to ensure that storage is dimensioned in such a way that at the slowest supply web speed adequate material web is stored in order to ensure a troublefree retraction and that the storage capacity is adequate at the highest web speed. As a result it is also possible when there are numerous closely juxtaposed, incoming material webs to be disposed of, the disposal device can run at the same speed or with the same separating frequency. Therefore disposal is largely independent of the quantity flow of the entering material web, so that it is possible to process jointly in a single device material webs having different average web speeds and alternating frequencies.  
         [0012]     The above and further features can be gathered from the claims, description and drawings and the individual features, both singly or in the form of subcombinations, can be implemented in an embodiment of the invention and in other fields and can represent advantageous, independently protectable constructions for which protection is claimed here. The subdivision of the application into individual sections and the subheadings in no way restrict the general validity of the statements made thereunder.  
         [0013]     In advantageous embodiments of the invention for the disposal of material webs, such as spent support films or foils for embossing objects supplied by an embossing means, the film is introduced via a slip drive into a storage chamber, where it forms freely hanging or spontaneously deposited loops. They form a reservoir for a discontinuous or alternating operation of the embossing device. The loops or packages can be individually cut in the disposal device or at the outlet from the storage chamber can be rolled up so as to from rolls.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS  
       [0024]      FIG. 1  shows an embossing device  11  with a following disposal device  12  for a material web  13 . The embossing and disposal of a single material web  13  is shown, but it is intimated that in many embossing processes numerous parallel material webs  13 ,  13   a  are used, which run through the embossing device and are disposed of in parallel.  
         [0025]     The material web  13  comprises a support foil or film, to whose active material web plane  29  are applied objects  19 , e.g. holograms or other flat portions to be transferred, which have a very limited mutual spacing. The objects are covered with a heat-sealing coating.  
         [0026]     Between two rollers  14 ,  15  of an embossing mechanism  16  is formed an embossing gap  17  in which an embossing tool  18  projecting somewhat over the surface of the embossing roller  14  transfers the object  19  to a product web  20  and firmly seals it there. To this end the tool  18  is heated to a heat sealing temperature and in certain circumstances the product web  20  is preheated. The product web can be in the form of paper or plastic webs, cardboard packagings, etc. to which are applied for decorative or security purposes objects  19  which are not to be moved merely by pressure. These can be finished prepared and defined objects such as holograms, pictorial representations, etc., or a specific form of an object can be transferred to the product web  20  by the embossing tool  18  from a material web uniformly coated e.g. with a metal coating.  
         [0027]     In order to transfer the objects  19  to the product web  20  with a greater mutual spacing than would be appropriate for economizing support film on the material web  13 , the latter is moved discontinuously, whilst the embossing rollers  14 ,  15  and product web  20  move at a continuous speed. The prerequisite is in most cases absolute synchronism in the speed of product web and material web in embossing gap  17 . Following the application of an object, the material web  13  is decelerated and this must not take place suddenly so as not to impair the sensitive film from which the material web  13  is formed. The material web is then retracted by the “deceleration path” and a following acceleration path counter to the supply direction  21 . This takes place during a time when the product web  20  and material web  13  run in uninfluenced manner between rollers  14  and  15 . Before the next point of product web  20  to be embossed reaches the embossing gap  17 , which is formed between the then once again incoming embossing tool  18  and the opposite roller  15 , the material web  13  is once again accelerated to the synchronous speed, i.e. the product web speed, so that embossing takes place in synchronism between them.  
         [0028]     This is implemented in that the material web  13  supplied from a not shown supply reel is metered in controlled manner by a control drive  22 , which e.g. operates with a suction roller  23 , which acts on the inactive material web side and, because it is positioned on the inflow side, i.e. upstream of the embossing gap, either releases or decelerates the material web.  
         [0029]     The actual conveying and uniform tension of the material web in the embossing gap  17  is implemented by a slip drive  24 , which is here shown as a suction roller  26 , which on its suction-active sensor  25  draws the material web with a force adjustable through the suction action onto the suction roller surface and then releases it again at the end of this sector. The suction roller  26  of the slip drive  24  runs at a speed producing a circumferential speed which is at least equal, but usually is somewhat higher than the synchronous speed in the embossing gap  17 , so that together with the sliding or rubbing characteristics on the surface of the suction roller  26 , a substantially constant tensile stress is exerted on the material web  13 . This also applies in the phases of retraction or stoppage between the deceleration, retraction and acceleration phase.  
         [0030]     It must be borne in mind that apart from the limited mass or weight of the material web, for the discontinuous movement of the latter no inertia force has to be overcome, because between the suction roller  23  of the control drive  22  and the slip drive  24  no mechanical parts have to be moved, apart from deflections, e.g. blow pipe deflection rods, but which can be designed in a low-mass or mass-free manner. It must also be taken into account that the long path between the embossing gap and the slip drive, which would appear to exist in the diagrammatic drawings, is only shown in this form to make understanding easier and in reality is much shorter with smaller deflections. The area of the material web  13  beginning with the control drive  22  and ending with the slip drive  24  is referred to hereinafter as the material web utilization area  27  and is followed by a disposal area  28  for the material web  13 .  
         [0031]     The above description of the embossing method and device applies to all the embodiments described hereinafter and is not to be repeated for them. These functions, as well as the disposal device functions described hereinafter, are driven and controlled by drives or electric motors by means of electrical or mechanical controls and transmissions. The drives are symbolized (M). In place of the suction rollers shown, it is also possible to use suction belt drives, particularly for the slip drive. In this connection particular reference is made to DE 198 42 585 A and its parallel applications.  
         [0032]     The disposal device  12  according to  FIG. 1  contains a storage device  57  with a storage chamber  30 , which is common to several parallel, incoming material webs  13  or can be subdivided between the same, particularly in the case of FIGS.  5  to  7 . It has an upper intake port  31  into which the flexible material web  13  runs from the slip drive  24  in a substantially vertical manner under gravity. In the storage chamber is provided a loop forming and separating member referred to hereinafter as support  32 . It contains suction and blow air ducts  33   a, b  and forms part of a holding device  34 . To this end it has on its top surface two holding surfaces  36  on both sides of a separating slot  35 . The holding surfaces  36  on either side of the separating slot  35  are in each case connected by suction ports to one of the two ducts  33   a, b  switchable between suction and blow air. The support is horizontally movable backwards and forwards between two positions located on either side of the incoming material web portion. In the drawing the left-hand position is shown in continuous line form and the right-hand position assumed to follow on to the same is shown in broken line form.  
         [0033]     The separating slot  35  belongs to a separating device  37 , which has cutting knives located on both sides of the intake port. On both sides of the cutting knives are provided spring-mounted holding posts  39 , which can cooperate with the holding surfaces  36 . To this end and for separation or cutting purposes, the cutting knife facing the support  32  is vertically movable through the separating or cutting drive  40  together with the holding post  39 . Although the suction ports provided in the holding surfaces  36  and which are linked with the suction air duct  33  the holding devices are able to hold the material web there, the holding posts  39  in conjunction with the holding surfaces  36  ensure a fixing of the material web whilst the cutting knife cuts the film. This is appropriate in the case of most support films due to their great elasticity and tensile strength.  
         [0034]     The support, including its suction air ducts and the holding devices, as well as the cutting knives with holding posts, can run through over the entire width (perpendicular to the drawing plane), i.e. can simultaneously dispose of several, juxtaposed entering material webs (cf. material web  13 ,  13   a ). The storage chamber  30  has a lateral discharge port  41 , which is connected to a suction air duct and is sucked off by means of the material web portions to be disposed of. Said portions can then be collected in a container, e.g. compacted by a press and supplied in type-pure manner for material recycling.  
         [0035]     The operation of the disposal device  12  will be described hereinafter relative to  FIGS. 1   a  to  1   e , the representations being reduced to what is absolutely necessary for describing operation.  
         [0036]      FIG. 1 a  shows that the material web  13  to be disposed of enters in free falling, vertical manner the storage chamber  30  through intake port  31  (cf.  FIG. 1 ) from slip drive  24 . As the leading or front, free end  42  of the material web  13  is secured by holding device  34  by suction air via suction air duct  33   a  and additionally the holding post  39  on holding surface  36 , at the left-hand side of the support located in its right-hand position a loop  43  is formed and is lengthened downwards by the supply of further material web.  FIG. 1   a  also shows that the right-hand bedplate  44  is moved downwards by its drive  40 , so that the leading end  42  of the material web is separated by knife  38  engaging in the separating slot  35 . The right-hand loop  43 ′ shown in broken line form was previously secured by suction air via suction air duct  33   b  and holding post  39 . Then and as shown in continuous line form, it is jettisoned as a separated loop  43   a , which now drops freely into the storage device and via discharge port  41  is sucked under suction action from the storage chamber. Thus, individual material web portions  45  are formed and are in loop form prior to separation and subsequently are disposed of as separated, double-deposited portions. For the jettisoning of the loop portion  43 ′,  43   a  switching from suction to blow air takes place in suction air duct  33   b , so that the up to then secured ends  36  of the separated material web portion are released from the holding surfaces  36 . They are then taken up by suction air connected to the discharge port  41  and are in the described manner supplied for disposal purposes.  
         [0037]     As the storage chamber  30  is closed, other than for the discharge port and intake port ( FIG. 1 ), also in the duct forming the intake port  31  and in the remaining storage chamber there is a downwardly directed air flow assisting material web guidance and loop formation.  
         [0038]      FIG. 1   b  shows the disposal device in the following operating position. The right-hand bedplate  44  of the separating or cutting device  37  has again been retracted into its upper, inactive starting position and the support  32  has been moved by its drive  47  into a position to the left of film entry. The loop  43  previously formed on the left-hand side is still secured with its leading end  42  by the holding surface  36  supplied with suction air via duct  33   a  and the material web is then placed over and beyond the holding surfaces  36  on the now right-hand side of the support and forms a new loop  43  there.  
         [0039]      FIG. 1   c  shows that the loop  43  hanging in  FIG. 1   d  on the left-hand side of the support is now separated from the continuous material web by the left-hand knife. After switching from suction to blow air in suction air duct  33   a , said loop  43   a  is also jettisoned and disposed of.  
         [0040]     Once again following retraction of the left-hand bedplate  44  and the change of support  32  to the right-hand side of the entering material web,  FIG. 1   d  shows the start of loop formation on the left-hand side of support  32 , which would then lead back to  FIG. 1   a  so as to conclude the operating circuit.  
         [0041]     It is more particularly apparent that in the entire operating sequence the storage device  57  through loop  43  there is always an adequate storage length in order not to impede discontinuous material web conveying through the embossing device. In spite of this and once again completely uninfluenced by these movements, there is a periodic separation of the complete material web into material web portions  45 , which can be disposed of much more easily than a continuous web.  
         [0042]     Apart from the differences stressed hereinafter, both the embossing device  11  and the disposal device  12  of  FIG. 2  correspond to those of  FIG. 1 . In this embodiment the support  32  is not movable horizontally between two positions and is instead positioned centrally roughly in the extension of the material web intake plane  48  in storage chamber  30 . Instead of a vertical movement of the bedplates  44 , the support  32  is movable vertically towards and away from the knife  38  through the action of the support drive  47   a.    
         [0043]     The material web  13  enters the intake plane  48 , but is then laterally diverted by a pivotable diverting duct  49 . The diverting duct  49  is formed between two jointly laterally pivotable components  50  actuated by a pivot drive  51  and carrying at their ends facing the support in each case one bedplate  44 .  
         [0044]      FIGS. 2   a  to  2   d  show the method steps corresponding to  FIGS. 1   a  to  1   e  for the embodiment according to  FIG. 2 . In  FIG. 2   a  a loop has formed on the left-hand side of the support  32  and at its front end  42  is secured by the left-hand holding surface  36   a . The opposite loop end is placed over and beyond both holding surfaces  36   a ,  36   b . Both ducts  33   a ,  33   b  are switched to suction air and on the right-hand side of support  32  is formed a new loop  43 , because the pivotable distributor  52  is pivoted to the right and the diverting duct  49  contained therein diverts the material web to the right.  
         [0045]      FIG. 2   b  shows that through the relative movement, here by raising the support  32  via drive  47   a  ( FIG. 2 ) and following engagement of the holding post not shown for reasons of clarity in  FIG. 2   b , the left-hand cutting knife  38  cuts through the material web at the point where it passes beyond the separating or cutting slot  35 . The suction air in duct  33   b  acts on the holding surface  36   b , so that the now front end of the loop  43  is secured. The suction air duct  33   a  is now switched to blow air, so that the material web portion  45  in the form of loop  43 ′ and then  43   a  comes free and can be sucked off on the left-hand side after once again lowering the support  32  and the holding posts of the left-hand bedplate have released the cut off material web portion.  
         [0046]      FIG. 2   c  shows that the distributor  52  has now been pivoted to the left, so that the material web, over and beyond support  32 , has been diverted onto the left-hand support side and forms a new loop  43  there, whilst that on the right-hand side is still connected thereto. Both holding surfaces  36   a, b  are subject to suction air action and secure the ends of the loop.  
         [0047]      FIG. 2   d  shows the cutting off of the right-hand loop  43  by raising support  32  and knife engagement, the jettisoned loop  43   a  only becoming free when the support  32  has been lowered again and the duct  33   b  has been switched to blow air. The same applies to  FIG. 4   b . The operating circuit is closed by the position according to  FIG. 2   a  again.  
         [0048]     In  FIG. 3  the modification compared with  FIG. 1  is that the support  32  has a linear/pivot drive  47   d , which pivots the support about its own longitudinal axis and can bring about displacement in two steps at right angles to the material web plane and intake plane  48 . The bedplates  44  with holding posts  39  are mounted, with the knives directed inwards, on the sides of the storage chamber, i.e. their knives are directed towards one another in a horizontal plane.  
         [0049]      FIG. 3   a  shows the situation where the support  32  is in its outermost, right-hand position, i.e. it is pressed against the right-hand bedplate  44  and cuts through the material web, which following horizontal moving out of the cutting engagement of knife  38  and optionally the switching off of the blow air on the side of the holding surface  36   a  jettisons the previously formed loop  43 ′. This takes place in the position of support  32  shown in broken line form in  FIG. 1 .  
         [0050]     Then and as shown in  FIG. 3   b  the support is moved to the left and pivoted counterclockwise by 180ø. The material web  13 , following onto loop  43  which has formed in  FIG. 3   a , runs over the support surface, which is rounded downwards, and now hangs downwards as a loop  43   a  to be separated and held at its free end  43  by the holding surface  36   b , whilst its other end extends beyond the support. A new loop  43  is now formed in a central position, but to the right of the support.  
         [0051]      FIG. 3   c  shows in mirror image to  FIG. 3   a  the situation where the previously formed loop  43 ′ has been cut off, in that the support is moved from the position assumed in  FIG. 3   b  into its extreme right-hand position, i.e. into cutting engagement. The loop  43 ′ is cut off and following retraction of the support  32  from bedplate  44  from the cutting position is ejected in the half-right position shown in continuous line form in  FIG. 1 . From said position there is then a movement to the right and the support  32  is pivoted clockwise by 180ø into the half-right position, in which the right-hand loop  43  is in the separating position and the new loop  43  has formed in the centre of the storage chamber ( FIG. 3   d ). From there the operating cycle continues with the position according to  FIG. 3   a.    
         [0052]     The supply of the holding surfaces  36   a, b  via ducts  33   a, b  with suction or blow air is illustrated in the drawings by s for “suck” and b for “blow”, express reference being made thereto. This applies to the complete application, also for the arrow representations illustrating movement directions and types. It is pointed out that more particularly in  FIG. 3  due to the normally vertical positioning of the holding surfaces  36  and the pivoting movement, in certain circumstances there may be no need to use blow air, because the suction action need not be too strong or can be entirely omitted. The loops  43  which are hanging completely vertically are in certain circumstances automatically jettisoned.  
         [0053]      FIG. 4  shows an embodiment in which the storage chamber wall, following onto a shaft-like intake port  31 , is adapted to a rotatable star or wheel. Here a four-arm star or a type of bucket wheel  32   a  is shown, whose arms  53  form between them storage cells or compartments  54 , which are clad with an ejector  55 , which is pivotably mounted about a bearing  56  close to the outer end of the arm and which is otherwise adapted to the storage compartment shape. At the end of each arm there is a separating slot  35  for cooperating with a cutting knife  38  and which at a bedplate  44  and together with the already described holding posts  39  is inserted in the storage chamber wall and is actuatable in the knife direction by the cutting drive  40  thereof.  
         [0054]     The method to be performed is as follows. The material web  13  drops under gravity from the slip drive  24  through the intake port into a storage compartment  54  located beneath the same of the support wheel  32   a  which is stationary in this position. The material web is then deposited in disordered or at least not completely ordered, loose loops in each case in superimposed, concertina-like form. A considerable length of material web  13  can be received in a compartment as a material web portion  45  in the form of a package  60 . On indexing the support wheel  32   a , the material web is placed over the outer end of an arm  53  and therefore over the separating slot. This takes place in  FIG. 4  by 90ø clockwise indexing of the support wheel  32   a . A package  60  is now formed in the next storage compartment  54 . In the meantime through the operation of the cutting drive  40  the bedplate  44  is moved into the storage chamber and therefore the cutting knife  36  is moved into the cutting slot  35  after the holding posts  39  on both sides of said slot have clamped the material web, which is then cut through.  
         [0055]     During the next indexing cycle the package  60 , which is cut free on both sides, is ejected from the storage compartment which is largely directed downwards in  FIG. 4 . The ejector  55  also flaps out and ensures a problemfree ejection, which is appropriate for many plastic films, because they could tend to adhere to the storage compartment walls due to electrostatic charging.  
         [0056]     Suction via discharge port  41  is as described hereinbefore.  
         [0057]      FIG. 5  shows a disposal device  12  starting shortly before the end of the utilization area  27 , which ends at the slip drive  24 . The disposal device  17  contains as a storage device  57  a plurality of juxtaposed storage chambers  30  for numerous parallel material webs  13 , which arrive with different average and effective supply web speeds and whose web, forward and reverse conveying conditions can differ considerably. From the slip drive  24  the material webs  13  pass in each case into a storage chamber  30  having a width which is somewhat greater than that of the material web, but in such a way that the storage chamber side walls  61  can guide the material web and the material web portions  45  formed for storage purposes in the form of packages  60 . The entire top side of the storage chamber can serve as the intake port. The storage chamber side walls  61  terminate in spaced manner from the chamber bottom  62 . An enveloping medium web  63  is led into the intermediately formed gap after having been unwound from a supply reel  64  and behind the storage chamber discharge port  41  is rolled up together with the material web packages  60  to form a roll  65  to be disposed of, winding taking place about a core optionally using a motor. As shown in  FIG. 5 , the side walls  61  are cut out corresponding to the shape of roll  65 .  
         [0058]     This leads to the formation of a package of disordered, largely superimposed, loose, concertina-like loops, i.e. with in each case successive bends or folds in opposing directions. It is clear that said package  60  stores a very considerable material web length, which even in the case of longer retraction movements enables the retraction of the material web from the disposal area  28  in stress-free, deformation-free manner into the utilization area  27 . A very compact disposal device  12  is created, with which a very compact roll  65  is produced, without the problems of conventional rolls arising and which are caused by the virtually impossible to control differing web lengths and conveying frequencies in the case of several parallel-running webs.  
         [0059]      FIG. 6  shows a device which, apart from the construction and function of the rolls  65 , coincides with that of  FIG. 5 . Here again all the packages  60  of parallel-running material webs  13  to be disposed of are formed on a packaging web  63 , which is drawn from a supply reel  64 , drawn along below the individual storage chambers  30  and finally rolled up again together with the packages  60 . However, this takes place on a sloping or tapered roll  66  which forms in that the axis  68  driven by a drive  67  in rotary manner has an angle differing from 90ø by several degrees with respect to the supply direction of web  63 . Thus, corresponding to the inclination angle the roll  66  runs in the direction of arrow  69  out of the disposal device and the packaging web  63  helically, but in overlapping manner envelops the roll filled with the material to be disposed of. Thus, in operation the roll  66  would permanently grow in the direction of arrow  69 . However, it is more appropriate to provide a cutting to length device  70  symbolized by a pivotable knife  61  and which cuts the roll into individual pieces  62 . The latter can be easily transported and supplied to recycling.  
         [0060]     The mutual matching between the disposal device drive and the operating speed of the embossing device is largely uncritical. The only requirement is that the disposal, i.e. the roll drive, is such that for the “slowest” material web  13  a package forms in order to ensure the requisite storage capacity, the other limit being the roll thickness. Between these the speed can be set such that there is an optimum disposal, even when taking account of the consumption of enveloping film  63 .  
         [0061]      FIG. 7  shows an embodiment which with respect to the storage chambers  30  and their function, particularly when forming packages, operates in much the same way as in  FIGS. 5 and 6 . However, here enveloping film is supplied in the vicinity of the chambers and instead the chamber bottom  62  is inclined to such an extent that the package  60 , on being drawn out of the storage chamber  30  at discharge port  41  automatically slides in the correct direction. To the bottom  62  is connected the upwardly bent jacket  73  of a stuffing winder  74 . The jacket  73  forms a conical sleeve widening in the direction of the roll outlet, i.e. in the direction of arrow  69 , in order to take account of the roll volume increase in this direction through the reception of further packages  60 . Here again the axis  68 , inter alia also due to the conicity of jacket  73 , is set at an angle to the perpendicular with respect to the orientation of the compartment walls  61 . The drive  67  acts on a stuffer or packer  75 , which is rotated for rolling up purposes, clockwise in  FIG. 7 , and simultaneously is moved backwards and forwards in the direction of axis  68  in accordance with double arrow  76 . The stuffer has vanes  77  tapering towards its free end and which consequently gives said stuffer  65  a conicity opposing the jacket conicity.  
         [0062]     At the outlet of the stuffing winder  74  is provided a storage reel  78  for the enveloping band  79 , which once again through inclined positioning surrounds in helical overlapping manner the roll. There is also a cutting to length device  70 , as in  FIG. 6 .  
         [0063]     Operation is as follows. The packages  60  forming in the storage chambers  30  slide as a result of the inclination of the storage chamber bottom  62  in the direction of the discharge port  41  and in this way enter the interior  80  of the stuffing winder. They are taken up by the vanes  77  of stuffer  75  and are wound up onto the same. The stuffer is then retracted, i.e. to the right and forwards in  FIG. 7 . The relatively elastic material will then immediately take up the space which has become free around the stuffer, so that on forcing the stuffer in again the complete roll  66  formed is advanced in direction  69 . The speed and oscillating frequency of the stuffer are adapted to the proportion of the material web to be disposed of and in this way a roll  66  with the desired density is formed and which is enveloped by the helically wound enveloping band. The cutting to length device  70  with its knife  71  cuts off the individual portions or pieces  72  and through a corresponding drive slides them in the direction of arrow  81  away from the roll axially for conveying away purposes.  
         [0064]     It is clear that this provides a particularly simple and effective disposal device, which is able to make available large quantities of material web to be disposed of in type-pure, easily handlable pieces, so that easy recycling is possible.
