Definitions

  • the invention relates to a winding device for winding a running material web with at least one knife for separating the material web in the web direction into several partial material webs and with a folding device for folding over the edges of the partial material webs.
  • Such a winding device is out US 8,221,298 B2 is known and is used in particular for the winding of stretch films.
  • document US2010 / 0012764 discloses a winding device with an oscillating winding method for a film with folded edges.
  • Stretch films are used to secure and pack individual goods, for example on pallets.
  • the goods are wrapped with the stretch film so that the goods are connected to each other using the self-adhesive stretch film.
  • edges of the film When folding the edges, it is therefore necessary to cyclically move the edges of the film laterally on the roll. This can be done, for example, by lateral oscillation of the roll or by means of guide rollers which can be moved at an angle after the individual-use cut.
  • An essential finding of the invention is therefore to oscillate the knife bar used for the utility cut transversely to the film direction.
  • the devices for folding the edges after the utility cut are either fixed to the same cutter bar and accordingly carry out the same oscillatory movement as the knives, or they are attached to a beam connected downstream of the cutter bar, which carries out an oscillatory movement synchronized with the cutter bar.
  • the folded edges are laterally laid on the resulting stationary wrap, and winding with reduced edge build-up is possible.
  • the stroke and frequency of the movement can be set here and, if necessary, can be adjusted depending on the web speed, film thickness and increasing roll diameter so that an optimal edge geometry is created.
  • the subsequent folding device for producing the folded side edge There are different variants for the subsequent folding device for producing the folded side edge.
  • One variant consists in that a folding device is provided for each folded edge.
  • Each of these folding devices can either be used directly next to one another or one behind the other. It is also conceivable that the devices for turning over the edges for approaching are immersed centrally in the cut - thus influencing them take both edges - and when immersed by suitable kinematics they are changed in position or shape in such a way that they only influence one edge. For adjacent edges, this can be done either simultaneously or one after the other.
  • Another variant of a folding device consists in producing and vacuuming a strip cut-out from several uses. The strip cutout would then already create a distance between the two edges, which makes it possible to fold the respective edges separately.
  • the invention has numerous advantages over the prior art.
  • the oscillating device comprises a driven belt to which the at least one knife is attached.
  • the belt can be, for example, an endless toothed belt that is moved via a toothed wheel that is driven by an electric motor.
  • the oscillating device comprises a cutter bar driven by a linear motor, to which the at least one cutter is attached.
  • a control unit for controlling the oscillation device is preferably also provided. All possible movement or cutting patterns can thus be specified via the control device.
  • the thickness profile of the wound roll is measured continuously and the oscillation device is controlled as a function of the measured thickness profile in such a way that the thickness profile is as uniform as possible.
  • the invention can be applied particularly advantageously to the winding of stretch films which have been produced on a cast film line or on a blown film line.
  • Fig. 1 shows a first embodiment of the invention.
  • the material web 101 is a stretch film produced on a cast film system.
  • the stretch film 101 is transported in the direction 102 after its manufacture and thus reaches the cutter bar 103.
  • the cutter bar 103 is moved back and forth in the direction 104 by an oscillating device and has a total of 5 cutting blades 105.
  • a waste 111 and 112 is created on the left and right, which can be further processed for other purposes.
  • S-shaped strips 106, 107, 108 and 109 are formed behind the cutter bar 103, approximately in the shape as shown in FIG Fig. 1 are shown.
  • the S-shaped edge does not have to be uniform.
  • the amplitude and frequency of the movement of the oscillating device can also be irregular.
  • Fig. 2 shows a second embodiment of the invention.
  • the material web 201 is in turn a stretch film produced on a cast film system.
  • the stretch film 201 is transported in the direction 202 and thus reaches the cutter bar 203.
  • the cutter bar 203 is moved back and forth in the direction 204 by an oscillating device and has a total of 3 cutting blades 205.
  • the outermost edges are left untrimmed on the left and right Fig. 1 no waste.
  • S-shaped strips 206, 207, 208 and 209 emerge behind the cutter bar 203, approximately in the shape as shown in FIG Fig. 2 are shown.
  • the S-shaped edge does not have to be uniform.
  • the amplitude and frequency of the movement of the oscillating device can also be irregular.
  • the outer strips 206 and 209 each have a straight and an S-shaped edge and are further processed in this form for special purposes.
