  • opposite edges of the Band material formed thinner than a central area of the same the thin Edges of adjacent sections overlap. This makes it possible to form the core with continuous thickness despite overlapping areas. Weight is also saved.
  • a constant thickness or wall thickness of the core arises in particular when the overlapping edges are taken together a thickness corresponding to the non-overlapping areas, for example the middle area.
  • the strip material preferably has a flat, rectangular cross section.
  • the edges are stepped to allow an overlap.
  • Marginal heels or steps have a thickness that is half the thickness of the Tape material otherwise corresponds.
  • Different strengths are also conceivable in the Area of opposite edges. It is important that the overlapping one another Edges taken together a thickness corresponding to the non-overlapping Areas.

  • the tension members are also arranged in the area of the edges of the strip material, at least in the area one of the opposing edges so that when the edges overlap Reinforcements are present over the entire length of the core. But this is imperative Not.
  • the band material is wound in a ring.
  • An endless ring is made from a finite section of the strip material by a Winding formed with only one turn. This ends up abutting each other of the band material connected together.
  • a core with a longer dimension in the axial direction is formed by permanent ones Connection of several rings.
  • the strip material is continuously screw-shaped and / or helical wound and thus forms the extending in the direction of a winding axis Core.
  • the strip material is preferably wound onto a mandrel, for example one motor driven mandrel.

  • a temporary coupling of the cutting device to the is also possible Core, such as by gripping elements that are released after cutting a finished core and hold on to the renewable core again after a push-back movement and hike with this.
  • FIG. 1 shows a fiber or a fabric helically wound material. In the present case, this is called strip material 11 designated.
  • the core 10 is hollow in the manner of a tube, see Fig. 2.
  • the inner diameter is, for example, 300 mm, the length of the core, for example, 350 to 400 mm.
  • the band material in the manner of a flat belt consists of thermoplastic and is preferably by extrusion or other continuous Process manufactured and can be armored.
  • Fig. 4 shows embedded in the tape material II
  • Tension members 12 which extend in the direction of the strip material and which are preferably run parallel to each other at equal intervals.
  • As a tension member wires, high-strength fibers and the like can be considered.
  • FIG. 3 A device for producing a spool core according to the invention is shown in FIG. 3 outlined.
  • the strip material 11 is fed via a stationary or stationary guide unit 13 fed to a mandrel 14 and comes to rest on this.
  • Spuldom 14 sits on a shaft 15 by suitable bearings 16 for absorbing transverse forces is supported and driven in a manner not shown.
  • the guide unit 13 is located directly on the mandrel 14 in front of the run-up point of the strip material 11.
  • the strip material 11 does not exactly match the mandrel 14 fed transversely to the winding axis 17 but at a small angle to it.
  • the angle is dependent on the width of the strip material 11 and just chosen so that by the winding process on the mandrel 14 immediately adjacent sections of the strip material 11 come to lie side by side without gaps. It is the strip material is helical or like a screw thread around the Spuldorn 14 wrapped around.
  • a resulting roll 19 becomes continuous through the supplied strip material 11 pushed further and can be almost any length.
  • a Core 10 with the desired length by an adjustable cutting device 18 from Winding 19 separated. The latter slides on the mandrel 14 so that a free end 20 migrates in the direction of the winding axis 17.
  • the mandrel 14 can be arranged in the direction of the winding axis 17 (not shown) Jacking devices, for example haul-off caterpillars, may be provided to the described To allow migration of the winding 19 on the mandrel 18.
  • the mandrel 14 does not extend all the way to the working area of the cutting device 18 and has a cross section that is constant over its length. In a not shown Execution tapers the cross section of the mandrel 14 in the direction of Cutting device 18. This prevents a tight fit of the winding 19 on the mandrel 18 with shrinking strip material 11.
  • the mandrel 14 is then preferably slightly conical.
  • the cutting device 18 is moving during the cutting process carried free end 20 to enable cuts exactly transverse to the winding axis 17.

  • the aim is to seal and / or smooth the cut surfaces, in particular the reinforcements or tension members 12 that may be present the cutting surfaces are exposed to heat.
  • Welding can preferably be carried out as Mirror welding, with hot air or as ultrasonic welding.
  • the band material 11 coming to rest on the mandrel 14 or its one another Adjacent turns are permanently connected to each other. This is shown in Fig. 3, a welding unit 21 is arranged approximately opposite the guide unit 13. lateral Edges 22, 23 of the strip material 11 are directly welded together or permanently connected in another way. This increases the strength of the resulting Core 10. A releasable connection is advantageous if the strip material 11 should be recycled, for example for cores of different diameters and / or lengths.
  • a surface configuration of the flat surface in the direction of the winding axis 17 is preferred Core 10. Nevertheless, the mutually adjacent sections of the strip material should 11 be well connected.

  • the strip material 11 can also have a laterally tapered cross-section. Suitability is important for as flat a surface as possible of the finished core 10, preferably partially Overlap of the strip material 11.
  • the reinforcement already described by the tension members 12 is preferably not over arranged the entire cross section of the strip material 11. Rather, the tension members 12 only in the central area 24 and in one of the two lateral edges 22, 23 available. 4, no tension members are arranged in the lateral edge 23. As a result this leads to the finished core 10 having tension members along its entire length equidistant from each other.
  • both lateral Edges 22, 23 can be equipped with tension members 12. A recess is also possible the lateral edges 22, 23 as a location for the tension members 12. In particular with relatively thick tension members in relation to the thickness of the side edges, this can be displayed.
  • the strip material preferably has a width of 120 mm.
  • One Flat belt can also be divided, so that several run side by side Partial belt, approximately 3 partial belts, each 40 mm wide, for the production of the core 10 be used.
  • the spool dome 14 must then also be next to each other coming partial belts are welded together.
