Abstract

An arrangement of an elongated element wound on a spool is presented. The elongated element has a leading end having a bent part and an unbent part. The bent part further having a beginning part and a trailing end. The leading end is positioned on the core of the spool and the bent part deviates at least for a part from a winding direction. The elongated element further forms subsequent windings in the winding direction on the core. At least one of the subsequent windings is wound over the beginning part of the bent part while an adhesive is provided to fix the trailing end of the bent part on the core simultaneously thereby securing elongated element on the spool.

First claim

The invention claimed is:

1. An arrangement of an elongated element wound on a spool generally in a winding direction,
said elongated element having a leading end,
said spool having a core,
said leading end being positioned on said core,
said leading end further comprising a bent part and an unbent part, at least said bent part deviating at least for a part from said winding direction,
said bent part further comprising a beginning part and a trailing end,
said beginning part being distinct from said trailing end,
said elongated element further forming subsequent windings in said winding direction on said core,
at least one of said subsequent windings being wound only over said beginning part,
wherein said arrangement further comprises an adhesive, said adhesive fixing only said trailing end on said spool.

2. The arrangement according to claim 1 , wherein a distance between said adhesive and said at least one of said subsequent windings is at least ten times the diameter of said elongated element.

3. The arrangement according to claim 2 , wherein said subsequent windings comprise a second winding, said second winding being also wound only over said beginning part.

4. The arrangement according to claim 1 , wherein said adhesive is a tape that is wound with one winding or revolution.

5. The arrangement according to claim 1 , wherein said adhesive is a tape that is wound with two windings or revolutions.

6. The arrangement according to claim 1 , wherein said bent part comprises a plastically deformed part.

7. The arrangement according to claim 1 , wherein said bent part forms an angle with the winding direction windings, said angle ranging from 10° to 170°.

8. The arrangement according to claim 7 , wherein said bent part forms an angle with the winding direction windings, said angle ranging from 30° to 120°.

9. The arrangement according to claim 1 , wherein said elongated element is a metal elongated element.

10. The arrangement according to claim 9 , wherein said metal elongated element is selected from the group consisting of a steel wire, a steel cord, a steel strand, and a steel rope.

11. The arrangement according to claim 1 , wherein the elongated element has a diameter between 0.1 mm and 4.0 mm.

12. The arrangement according to claim 1 , wherein the beginning part deviates from the winding direction in one direction towards one end of the spool and is bent in an opposite direction towards the other end of the spool towards the trailing end.

13. The arrangement according to claim 1 , wherein the at least one of said subsequent windings is wound only over said beginning part on one part of the core, and said adhesive fixing only said trailing end on said spool is on a different part of the core.

14. A method of securing an elongated element to a spool where said elongated element is wound generally in a winding direction, said spool having a core, said method comprising the steps of:
a. providing an elongated element with a leading end;
b. forming a bent part and an unbent part in said leading end;
c. positioning said leading end onto said core, said bent part deviating at least for a part from said winding direction;
d. forming a first winding wound only on a beginning part of said bent part on said spool in said winding direction; and
e. providing an adhesive only over a trailing end of said bent part.

15. The method according to claim 14 , wherein subsequent windings comprise a second winding and wherein said second winding is wound only over said beginning part.

16. The method according to claim 14 , said method comprises a step of plastically deforming said bent part.

17. The method of according to claim 14 , wherein said step of providing an adhesive is done without interrupting the formation of subsequent windings.
