Definitions

  • This invention relates to a process and apparatus for stacking or storing delicate thin webs of material in which a web of material is formed into a rotatably mounted stack which contacts a support at least at three contact areas over the entire width of the material, the contact pressure being limited by a resilient effect of the contact areas, and the speed and stress differences of the web occurring when passing the contact areas being compensated by a movable roller which is contacted by the web before it contacts the stack.
  • This invention relates to a process and apparatus for stacking or storing delicate thin webs of material, e.g. those of cellulose or plastic film, which are taken over at a tensile stress acting continuously from the lower plies of the web of material through the individual plies to the top ply.
  • a process in which a web of material is stacked to give a rotatably mounted stack and, at least at three places, is contacted over its entire width, the value of the contact pressure being limited by a resilient effect of the contact areas, and the speed and tension differences oftheweb of material occurring when it passes the contact areas are compensated by a movable support which it contacts before impinging on the stack.
  • Suitable webs of material for stacking or storing according to the process of the invention are delicate thin cellulose or plastic sheet materials which may be' surface-treated or coated.
  • the width of the web of material to be stacked or stored corresponds at least to the height of the stack.
  • the width may have any value so that any delicate thin web of material from a production machine can'be stacked according to the process
  • the process of the invention for stackingor storing differs distinctly from a winding-up process since it clearly differs from the conditions of the latter process by the present freedom that themat erial is not forced to yield to the interior.
  • the number ofthe contact areas substantially depends upon the dimension of the-support and is limited only in that a polygonal form is maintained also after completing the process. A conversion into the circular form must be avoided since thenall disadvantages of circular winding would again become apparent.
  • the number of the contact areas is at least three or more, but it would be particularly suitable to stack on supports with 4 to 12 contact areas. In the case of a support diameter of 200 mm., 6 contact areas are used, for example. The number of material is contacted over its entire width since, otherwise,
  • the contact areas are resilient and may be mounted on the support or may be a part of the support.
  • the contact areas alone form the contact lines for the stack to be supported.
  • the web of Stacking or-storing according to the process of the invention necessarily leads to speed variations.
  • a substantial feature of the process is to absorb orcompensate these variations before the web of material impinges. This is achieved in that, before the stacking or storing operation, the compensating function is transferred to a movable support by a movement in the sense of shortening the web of material. The tension differences in the web of material to be stacked are thus also considerably avoided.
  • the present invention also provides an apparatus for the performance of the process for stacking or storing delicate thin webs of material, which are taken over at a tensile stress acting from the lower plies of the web of material through the individual plies upon the upper one.
  • FIG. 1 is a schematic view in elevation of one embodiment of the apparatus ofthe invention,.and
  • FIGS. 2-5 are perspective views of supports employed in the apparatus ofthe invention.
  • a roller 6 For placing a stack 2 on adimensionally stable support 1 at least three ribs 4 of a resilient structure or with a resilient indcntable sure surface are provided for the entire width of the web of material 5 and, for compensating the speed and tension differences ofthe web of material 5, a roller 6 is provided which executes an oscillating movement.
  • the ribs 4 mounted on the support I may have any cross section, e.g. a circular, semicircular, angular or oval cross section. It is also possible to form the ribs 4 as hollow sections or as hollow sections with an adjustable pneumatic internal pres sure.
  • the cross section of the support 1 may have any basic form, but preferably it has a circular crosssection.
  • roller 6 The operation of the roller 6 is as follows:'in its nonoperating position and'without the action of the mean web tension of the material concern'edwith. avoidance of too low or too By means of the specific resiliency of the Contact areas,
  • the tension differences in the web of material 5 also are simultaneously compensated or at least suppressed to such an extent that the stack formation cannot be impaired by stress concentrations in the web of material 5.
  • the weight of the roller 6'advantageously has such a value that the forces available for deflectionare sufficient to overcome the acceleration and retardation forces opposed to the roller movement because of the mass moment ofinertia.
  • the distance may be provided by advancing the axis 13 or, in the case of a stationary position of the axle ll of the stack 2, may be provided by changing-the pivot 9 of the roller 6 or by other known means. Advancing may be performed manually or automatically by means of known scanning devices, e.g. light barriers, switches with scanning rolls, and the like.
  • the apparatus of the invention also may be employed when,
  • lt must be adapted to the characteristics of the web of material to be stored or stacked and normally exhibits decreasing values with an increasing stack height.
  • the lower plies may freely sink downward between-the individual ribs 4; but the pressure in the contact range does not reach a value above that predetermined by the elasticity of the ribs 4.
  • the good surface adhesion produced therewith considerably limits the possibility ofa relative displacement of the plies to one another, which may be initiated by the continuous transfer of the tensile stress, and this permits operation with a substantially lower tensile stress than in the cascof the windings of the prior art without the layers beinglaterally displaced or the lower layers being addi-
  • the vertical distance between the roller 6 and the stack 2 is limited to a few centimeters and can be maintained approximately constant by advancing the axle ll about the axis 13. Advancing is performed manually or automatically by known scanning devices, not illustrated. It also is possible to perform the advancing movement at the pivot 9 ofthe roller 6.
  • Support-ing of the stack 2 is performed substantially indirectly by the support 1 which, in this case, has six semicircular ribs 4 which are positioned transversely to the stack direction over the entire width of the web ofmaterial.
  • the ribs 4 have a resilient structure or have resilient indentable surfaces.
  • the ribs 4 are mounted on the support 1; they also may be a part of the support 1.
  • FIGS. 2, 3, 4, and 5 show some embodiments of the ribs 4 which, for example, are mounted on a cylindrical support 1.
  • dimensionally stable surfaces 7 of metal or synthetic plastic are adapted to and mounted on the resilient ribs 4 where the web of material to be stackedcontaets the ribs and, furthermore,- the dimensionally stable surface 7 is sufficiently distanced from the, support 1 so that the resilient indentability of the ribs is not impaired.
  • H6. 3 shows ribs 4 of a resilient structure with full profile consisting, for example, of rubber sponge, which are mounted'on the support 1.
  • FIG. 4 shows an oval 4" and FIG. 5 a round resilient hollow section 4". Both types of profiles-are filled with a predeterminable air pressure and thus can be better adapted to the use concerned, after the stack.
  • the degree of elasticity, if required, may have an upper value very-close to that ofa rigid structure.
  • An apparatus for stacking a delicate thin web of material which comprises rotatable support means having at least three resilient ribs on the surface thereof, the ribs having a length at least equal to the width of the web and a height sufficient to support the stacked web in a polygonal configuration, and a pivotally suspended rollermeans mounted adjacent to the tionally pushed away downward by loop formation of the I upper layers, despite which a transportable and storable stress-free stack is formed and delicate thin webs of material are. protected to a particularly high extent.
  • lateral discs or lateral supports such as are employed in the case of reels, and which usually would interfere with subsequent processing of the stack are advantageously eliminated.
  • a web of material 5 is conveyed over a roller 10 toa stack 2 and stacked there. Conveying the web of material 5 over the ribs 4 and the continuous ply'on the stack 2 results in different distances with respect to the axle 11, causing corresponding speed differences which are compensated by a roller 6 movable in the swinging arms 8. A condition is thus provided for the trouble-free stacking of the succeeding layers-on the stack 2.
  • the stack 2 is formed by rotating the support 1 about the axle ll.
  • An apparatus including means for advancing the center of the rotatable support means, whereby a distance of a few centimeters is maintained between between material on the support means and the roller means.
  • a process for stacking a delicate thin web of material which comprises passing the web over a pivotally suspended roller and then onto a rotatable support having at least three resilient areas on the surface thereof in contact with the web and serving to support the stacked web in a polygonal configuration, the speed and stress differences of the web occurring when passing over the resilient areas being compensated by the roller.
