Definitions

  • the invention relates to a winding device for webs with two winders, which are equipped with winding holders that can be attached to both sides of the web and are mounted together with an upstream deflecting element in an axially parallel manner on a rotatable console and can exchange their position by pivoting the console through 180 ° and alternately in a winding position a commenced winding are operated starting done by wrapping and in a waiting position a new roll, and with an independently supported by the console T racing device on a web section between the be: acting the winders, and in which the web of the deflecting element in each degree of filling partially wrapping the resulting winding and then only being brought into contact with the resulting winding after this wrapping,
  • Such a winding device for plastic films is known from DE-AS 2 317 325, in which a tube as a winding core is clamped between the two winding holders of a winder, on which the plastic film is then wound.
  • a pressure roller rests on the cut of the film web and presses it against the winding core until this cut sits firmly on the winding core.
  • Such a pressure roller causes wrinkles in the winding in the case of webs which tend to form folds, as is the case in particular in the case of doubled and multilayered cloth webs, which are undesirable.
  • the object of the invention is to design a device of the type mentioned above so that even with manure to F alternatebil- sloping webs such wrinkles are avoided if possible, especially if flat coils are wound on winding cores brettchenförmige. In doing so, forced breaks at the start of a new winding should be shortened as much as possible.
  • the invention is characterized in that the web of material is guided tensioned between the winding holders of the winder in the waiting position and to the winder in the winding position.
  • the winding supports are equipped with clamping elements, in that the winding support by axial displacement from a remote position adjacent the web, they in W artestel- lung occupy the associated winder, are adjustable in an attached position in which the clamping elements together with the edge of the web of a grasp the inserted winding core and clamp it and take it in during winding, and that an anti-rotation device is provided for each reel holder, with which the associated clamping elements are locked in the waiting position in a rotational position in which they are aligned with the plane of the web being passed.
  • the material web is clamped only at its edges in the spread tension in which it is kept ready, the ends of the winding core being clamped at the same time. This maintains the tension, even in the individual layers of a doubled or multi-layered sheet, so that, as experience has shown, undesirable wrinkling can be avoided.
