Definitions

  • the present invention relates to a take-up spool for winding and unwinding winding goods, such as Tapes, wires and the like with a winding tube and with two flange disks, which are provided on the facing end faces with elevations forming a profile.
  • the take-up spool in question is made of an impact-resistant plastic and is H-shaped in longitudinal section.
  • the side flange disks serve to limit the winding material wound on the winding tube and as an abutment for the rotating support flanges of a winding machine.
  • the elevations are radially extending ribs which are arranged at a relatively small angular distance from one another. These ribs in particular reinforce the flange washers so that they bend little. In addition, they must be designed so that they withstand the centrifugal forces, which are very high, especially at the start of a winding process.
  • the speed at the start of the winding process is, for example, 4,000 rpm.
  • the present invention has for its object to provide a take-up spool of the generic type with a significantly higher impact resistance.
  • elevations forming the profiling are designed as projecting cams which are arranged on at least one circle which is concentric to the winding tube and has a larger diameter than the winding tube and whose outer surfaces lie in a plane parallel to the inner surfaces of the flange disks.
  • the total cross-section of all cams is significantly smaller than the total cross-section of the ribs in the previously known designs. This does not lead to extreme material accumulations, so that the forces acting on the flange disks are distributed more evenly when the take-up spool falls. This incredibly simple measure also saves material. In addition, the take-up spool can be wound more frequently, so that the number of take-up spools to be disposed of is also reduced.
  • the cams are arranged on several, preferably on three circles concentric to the winding tube are.
  • the distances between the individual cams on each circle concentric to the winding tube are expediently arranged at the same distance from one another, since care must be taken to ensure that the cams do not cause any imbalance.
  • the cams on the individual circles are arranged at the same angular distance from one another, which means that the radian measure between two cams on the outer circles is larger than that on the inner circles. So that the take-up spool produced in the injection molding process is to be removed from the mold, it is provided that the cams are conical in such a way that the cross sections decrease towards the free end.
