Definitions

  • the invention relates to a method for winding a tapered film web, in particular plastic film web on a winding tube.
  • the invention further relates to a Winding device for performing the method.
  • a Winding device for performing the method.
  • At the incoming film web, in particular plastic film web it is usually one with high Speed fed web. That is why they are special Measures required to ensure a reliable function Winding the film web realized on winding tubes can be.
  • the known Winding devices becomes an incoming plastic film web first wound on a first winding tube, that between a first pair of about a central axis pivoting mounting arms is included. If the on the first winding tube, the resulting film roll, which also Coil is called, is completely wound, the first swings Pair of pick-up arms with the finished wound film wrap after a transverse separation of the film web into one Removal position. The new one created during cross-cutting The beginning of the web is wound on a second winding tube, who now have a second pair from around the Central axis swiveling mounting arms in the Winding position was transferred. The two pairs of Arms are clockwise or counterclockwise Can be swiveled clockwise around the central axis. As part of the known method, the film web is alternately on one between the first pair of support arms recorded winding tube and one between the second pair wound from the take-up winding sleeve.
  • the above explained type is usually a so-called "Contact winding” performed.

  • the receiving device or the Area of the transverse separating device assigned to the receiving device can thus when swiveling around the swivel axis retract as it were towards the swivel axis.
  • the second Pair of support arms the new second winding tube on the Path between the removal position and the recording position fed.
  • the new second winding tube to the second pair of Admission arms is fed only in the acquisition position.
  • the new second winding tube is also from the receiving device of the cross separating device or supported and also the cross cutting device is about its pivot axis from the shooting position in the Waiting position swiveled.
  • the angular distance ⁇ of the first pair of support arms with the Foil wrap in the wrap position to the second pair of Support arms with the new second winding tube in the Waiting position minimized and expediently in Depends on the diameter of the film roll.
  • the Distance of the first pair of support arms in the winding position to the second pair of support arms in the The waiting position is expediently set such that the angular distance ⁇ ⁇ 80 °, preferably ⁇ 70 °, very preferred Is ⁇ 60 °.

It is within the scope the invention that the first pair of receiving arms with the film roll is moved in the direction of the removal position and simultaneously, preferably synchronously, the second pair of Holding arms with the new second winding tube in the Winding position is pivoted, then the new second Winding sleeve is pivoted to the only contact roller. Swinging onto the contact roller means in this Connection does not necessarily mean that the winding tube has a has direct contact with the contact roller.
  • the incoming Foil sheet arranged.
  • the new second winding tube is expediently after as before from the receiving device of the cross cutting device recorded or supported.
  • the angular distance between the first pair of support arms in the transition position and the second pair of take-up arms in the winding position minimized and expediently in Dependence on the diameter of that of the first pair of Pick-up arms of wrapped film.
  • the angular distance is preferably ⁇ 80 °, preferably ⁇ 70 °, very preferably ⁇ 60 °.
  • the cross-cutting device is an embodiment of the invention after transverse separation of the film web by swiveling the assigned swivel axis to a rest position transferred. If there is another new winding tube from the receiving device of the cross cutting device is to be included, the cross cutting device again by swiveling around its swivel axis in the Recording position moved.
