  • a particular problem with the winding of winding cores or cores with a web start is that the winding rolls to be wound up are asymmetrical, which means that they have sides with different properties. Depending on the further processing of wound up to winding rolls webs, it is therefore desirable that one or the other side is located on the winding roll outside.
  • it is necessary to drive the feed roller and the winding core or the winding tube with opposite directions of rotation what it makes it necessary to supply the web beginning of the winding tube formed by separation of the web depending on the direction of rotation from opposite directions of the feed roller.

  • the process of the invention can be operated at web speeds in a typical range of about 30-400 meters per minute or more. It is advantageous if the speed of the air flow at the respective actuated suction slot is at least twice and preferably at least three times higher than the running speed of the material web. Preferably, the suction air flow is thereby directed to flow around at least about 3/4 of the circumference of the winding tube (i.e., at least 270 °).

  • the respective "downstream” ie in Fig. 15 in the direction of movement R of the web B "back” lying shell 131 and not in the direction of movement "upstream” or more "front” lying shell 132 is actuated.
  • This operation is effected in that the respective interior of the corresponding chamber is connected to the vacuum sources, here for example by operation of the slide 334 coincides so that the opening 335 in the slider with the opening 325 at the upper end of the shell 131 matches and thereby the Innraum 310 of the shell 131 is connected via the interior 330 of the carrier 133 with the vacuum source.
  • the suction gap 319 of the shell 131 close to its lower end E1 (FIG. 14), the suction air flow guided through the channels 136, 137 upon actuation of the shell 131 surrounds the winding tube in almost the same amount.
  • each successive layer of the film web B running onto the winding sleeve 121 fixes the layers already thereon so that a tension-proof connection between the film web B and the winding sleeve 121 is achieved, i. the critical part of the Anwickelvorgangs is completed and the angepeite with multiple layers of the film web sleeve 121 as described above can be transferred from the first to the second winding station.
  • the Anwickelvorgang runs in an analogous manner, ie the front end of the web B is wound by means of the suction air stream, which in turn is sucked through the column 351, 352, but this time by actuating the shell 132 by connecting the associated interior space 320 to the vacuum source via the slides 334 shifted to release the 324 and the suction air flow resulting thereby first into the channel 137, then the channel 136 and finally through the suction gap 329 at the free lower end E2 of the shell 132 runs.
  • the separation process is effected by the separator, which tapers next to the gap 352.
  • Figure 16 illustrates the principle of a preferred web separation device 140 according to the invention which is useful not only for the web winding method or web wrapping apparatus described herein but also for other purposes requiring rapid, secure and smooth cutting of a web, especially a polymer film web , require.
  • a web separation device 140 is essentially based on the fact that several, e.g. via a slide 142 motion-connected tip separating elements 141 in the radial direction (ie, the directions of the double arrow MR) through the (not shown in FIG. 16 slot in the shell of the winding drum are guided outwards and perforate the web B accordingly, and also in the axial direction (ie, in the direction of the double arrow MA), at least to the extent that each of the elements 141 travels at least one length L distance corresponding to the distance between two adjacent elements 141.
  • the initial perforation of the web B is achieved by means of the sharp side edges 411, 412
  • this separation technique is advantageous for the web separation of the usually extensible polymer films.
  • the separating elements 141 are arranged on the slide 142 formed as a guide slide, which is guided in a manner not shown that of the recesses 143 and the fixed guide pin 144th at each actuation of the drive 148 in the direction of the double arrow MA first in the radial outward direction for contact all pointed separating elements 141 brought to the film web, then laterally in the axial direction and finally in the radial direction is moved inwards.
  • the pointed separating elements 141 cause this first a perforation and immediately connect thanks to the axial movement by means of the cutting edges 411, 412 a cutting through the film web.
  • the limitation of the movement in the axial direction defined by the openings 143 can certainly be greater than the distance between two adjacent separating elements 141, in particular if this ensures the safety and completeness of the web separation.
  • the movement of the separating elements in the axial direction need not necessarily be linear, but may be e.g. Wavy zigzag course, with appropriate adjustment of the passage openings for the separating elements in the shell of the winding roller.
  • the drive 148 preferably generates a sudden movement which is completed in fractions of a second, typically less than 0.1 sec. This determines the duration of the separation process, which in turn can be adapted to the web speed.
