  • one, in particular on the leader side of the machine arranged for manufacturing transport device is present, by the rollers from the take up to wound-up strips can be transported away.
  • At the cutting device is preferably also a gluing station for bonding attached to the end of the wound into a roll strip of the roll.
  • the device as a whole or attached to her cutting device automatically, in particular hydraulically, pneumatically or by means of a Electric motor, along the lateral surface of the winding roll parallel to its longitudinal axis movable.
  • the outer layer committee removed, by peeling or cutting strips from the top Position of the winding of the material web is formed.
  • a winding machine includes, inter alia, as a Anpresstrommel or Carrying drum designated winding roller 17 (Fig. 1).
  • a material web will either from a calender, not shown here, a calender, a Final group of a finishing machine or a dryer section of a Paper or board machine led out, then wraps usually a Leit- or Spreader roller and runs on the lateral surface of the winding roller 17, wraps around this at a certain angle to one between the winding roller and a winding roll 1 existing nip and finally on the winding roll. 1 wound.
  • the winding roll 1 (Fig. 2) is wound with a roll of a fibrous web and is located in a winding device or elsewhere in a machine for producing or refining a fibrous web.
  • the winding roll 1 is rotatable with its shaft 2 in a bearing bracket with side walls 3, 4 stored.
  • the winding roller 1 is preferably also driven (Center Drive).
  • a cutting device 5 On the underside of the winding roll is a cutting device 5 between terminal strips 6, 7 arranged.
  • Two conveyor rollers 8, 9 serve to transport a Strip 10 from one layer or from several layers of the coil.
  • the terminal strips 6, 7 are preferably integrated in a traverse of the winding unit, which also receives a Beerabquetsch sensible.
  • Such Beerabquetsch is known for example from EP 0 788 991 B1 or EP 0 741 373 B1.
