Definitions

  • the invention relates to a method for winding material webs, in which a material web unwound from a mother roll, cut in a cutting section in its longitudinal direction in partial webs and wound up again in a retractor, wherein individual winding stations are provided for winding the partial webs.
  • the invention will be described below with reference to a paper web as an example of a material web. However, it is also applicable to other webs that can be handled in a similar manner.
  • a winding device is used in the sequence of a slitter, in particular a back-up roll slitter, to which the invention is particularly advantageously applicable.
  • the resulting paper webs are wound up for further processing or transport on empty reeds and then often called full reels or mother rolls, which currently usually reach lengths of up to 10.5 m, diameter of over 4 m and weights of up to 170 tons.
  • full reels or mother rolls which currently usually reach lengths of up to 10.5 m, diameter of over 4 m and weights of up to 170 tons.
  • slitter-cutting machines which essentially consist of a unwinding device, a cutting section and a roll-up device, wherein the cutting section has a number of disk-shaped cutters adapted to the possible pitches.
  • each individual roll to be wound is wound in a separate winding station around a winding tube in the retractor according to the prior art.
  • the Railbahn- or finished rolls are supported during the winding process on a support roller or are at this.
  • winding stations those places are defined at which a winding takes place.
  • winding stations consist of two winding blocks.
  • Basis of a winding frame forms a base frame which is movable transversely to the paper web on a rail or carriage system and at its upper end a guide rail is formed on which a guide carriage can move in the running direction of the paper web.
  • the guide carriage receives a rotatably mounted end winding, which engages the winding in the sleeve and is driven by a gear via a motor. Since this motor drives the winding of the partial web roll from its center, it is usually referred to as a center drive, but may also be generally called drive or winding motor.
  • peripheral drives in particular Reibrad- or friction roller drives, known to drive a mounted in a frame wheel / roller, which rests on the circumference of the winding and the partial web wound on its peripheral surface via friction. Since here, however, the friction wheel or the friction roller is driven in a similar manner by winding motors provided, the statements made in connection with the center drives apply mutatis mutandis to this winding principle. Likewise, the statements made above apply mutatis mutandis, if the Wickelböcke not based on a base, but are mounted on a, arranged on the support roller, Traverse.
  • the unused winding stations of the prior art are extended laterally out of the machine into a so-called winding station or remain unused in an intermediate position within the production space.
