Definitions

  • the invention relates to a method for Winding of tape-shaped material to tape rolls and Change of roles and on devices for implementation of the procedure.
  • the invention is based on the object Method and device for winding to create tape-like material to tape rolls, in which a flying change of roles is possible.
  • a winding drum is provided over the part to be wound up along part of the circumference band-shaped material is wrapped around the band-shaped To drive material.
  • a winding core which is a cardboard tube can be used to wind the tape, by pushing the Winding drum wrapping band is pressed and the end of the tape adheres to the winding core. This way it grows the spool wound on the winding core, and when the roll has reached its intended size, will be wound up Cut the tape across and the end of the tape on the finished spooled reel secured.
  • the winding core with the sleeve accelerates along the belt until the Winding core to the speed of the tape and thus the Peripheral speed of the winding drum has reached, so that there is no relative movement between the tape and the winding core. Then the tape is cut transversely to a tape end for the reel already wound and a beginning of the tape for the to generate new winding core. The new beginning of the band is with the new winding core is guided along the winding drum, the guiding speed gradually compared to the Rotational speed of the winding drum remains and it so for winding the new tape end onto the winding core is coming.
  • Winding up becomes finished that the winding core passed to a holding device which grips the two ends of the winding core and the wound winding core as the beginning of a role against the Winding drum holds with a certain contact pressure. Thereby the reel is driven and constantly rewound supplied tape, causing the roll to grow until it has reached its intended size. Then the Role change, as already described.
  • the end of the tape can be secured to the finished roll be, for example by means of one or more double-sided adhesive tape.
  • the backup can also by additional or alternative packaging of the spooled reel can be achieved to counter it as well Protect damage and UV radiation. This can for example in an automatic packaging station happen in which the complete role on the scope with is wrapped and sealed in a plastic film.
  • the cross is cut winding tape. So that the tape evenly on the Winding core is wound, it is necessary that the Cut perpendicular to the band stretching and Belt conveyor direction. According to the invention this is thereby achieved that the cut along a generatrix the take-up drum takes place, and that is through a knife drove a slit that runs along a surface line the take-up drum extends. This makes an absolute safe cut achieved perpendicular to the tape direction.
