  • this object is achieved in that at least one Cutting element having cutting device for removing the coil of Material web is provided, wherein the winding roll a rotational movement to Unwinding of the winding takes place and the winding drum as well as the at least one Cutting device in the traverse direction relative to each other are movable. It In particular, several cutting devices can also be directed onto the winding to cut it into narrow, easily removable strips. If the cutting devices in addition to each other also be moved and for example, with different speeds compared to the winding traversing on the wrapping drum will be during the unwinding of the roll produced by the winding drum pieces from the web. The width of the Strip packages can be over the rotational frequency of the winding drum and / or over the Traversing be varied.

  • the invention also relates to a method for removing the roll the web of the winding drum in a device, in particular a Tambourablagestation, the type described above.
  • this object is achieved in that the cutting device at an acute angle or at a 90 ° angle with respect to the longitudinal axis of the winding drum is employed on the lateral surface and that the Winding drum rotates while the wrapping drum and cutter relatively be moved towards each other in the direction of the longitudinal axis of the winding drum.
  • the winding cylinder and a traversing device By simultaneous rotation of the winding cylinder and a traversing device The wrap is made into spiral narrow, easily treatable Strip packages separated.
  • the traversing movement coincides with the Cutting realized. It must be at the rotational speed depending on the angular position of the wrapping drum are synchronized.
  • the traversing movement is either through the cutter or through the winding drum or by a movement of both the cutting device and the Wickeltambours reached in the longitudinal direction.
  • the winding tambour has a large diameter and thus a larger Restschwarte has, is the traversing with the rotating cutting blade repeatedly until there is only one remaining rind with a small thickness, for example in the range of five to one hundred millimeters, on the winding core located.
  • the remaining rind up to the Tambourkern is then either with the rotating Circular knife removed in combination with the surface-protecting knife or exclusively with the surface-sparing knife, which consists of a particular consisting of plastic overlay and a knife blade.
  • the sliding layer slides to remove the last remaining rind on the Tambour surface, without damaging it, lifts the bottom material web layer and leads them to the knife blade.
  • an alternative method for removing the roll of the web from the winding tuft is provided that for removing the roll of the Material web of the winding drum in the Tambourablagestation the cutter at an acute angle or at a 90 ° angle with respect to Longitudinal axis of the winding cylinder is employed on the lateral surface that the Winding is cut annularly by the cutter, wherein after Carrying out in each case an annular section of the winding drum and the Cutting device relative to each other in the direction of the longitudinal axis of the winding drum be proceeded that after performing all annular cuts the winding drum and the cutting device relative to each other by 90 ° in the be pivoted horizontal plane and that subsequently the winding in Direction of the longitudinal axis is cut.
