Abstract

The invention discloses a coil for a winding-up device adapted for winding up a cutting wire used for cutting through an adhesive bead of a bonded-on pane, having a coil body for winding up the cutting wire, the coil body being provided with at least one opening for securing one end of the cutting wire.

Claims

1. A coil in a winding-up device configured for winding up a cutting wire configured for cutting through an adhesive bead of a bonded-on pane, said coil comprising:

a coil body for winding up said cutting wire;

at least one opening provided on said coil body and being configured for securing one end of said cutting wire;

a coil axis on which said coil body is detachably fastened;

a cover detachably fastened on said coil axis;

a first spring-loaded locking mechanism provided on said coil axis for securing said cover;

a second spring-loaded locking mechanism provided on said coil axis for fixing said coil body on said coil axis;

wherein said first and second locking mechanisms cooperate one with the other so that said coil body is detachable from said coil axis together with said cover.

2. The coil of claim 1, wherein said coil body consists of at least two parts that are detachably connected one with the other.

3. The coil of claim 2, wherein said first and second locking mechanisms cooperate one with the other so that the two parts of said coil body can be released one from the other after having been released from said coil axis.

4. A coil in a winding-up device configured for winding up a cutting wire used for cutting through an adhesive bead of a bonded-on pane, said coil comprising a coil body for winding up said cutting wire, wherein said coil body comprises at least one opening configured for securing one end of said cutting wire.

5. The coil of claim 4, wherein said at least one opening is configured as a cylindrical bore or as a slot.

6. The coil of claim 4, wherein said coil body comprises a plurality of segments which commonly form an outer contour configured for receiving said cutting wire when winding up on said coil, at least one space being formed between said segments.

7. The coil of claim 6, wherein said coil body comprises:

an axis of rotation; and

a plurality of web-shaped segments that are arranged, in radial direction, at equal angular spacings one relative to the other along a circle concentric to said axis of rotation.

8. The coil of claim 4, wherein said coil body further comprises two flanges spaced from each other that commonly define a coil chamber configured for receiving said cutting wire when winding up on said coil.

9. The coil of claim 4, wherein said coil body consists of at least two parts that are detachably connected one with the other.

10. The coil of claim 4, further comprising a detachable cover.

11. The coil of claim 4, further comprising a coil axis on which said coil body is detachably fastened.

12. The coil of claim 4, further comprising a coil axis on which a cover is detachably fastened.

13. The coil of claim 12, further comprising a first spring-loaded locking mechanism provided on said coil axis for securing said cover.

14. The coil of claim 13, further comprising a second spring-loaded locking mechanism provided on said coil axis for fixing said coil body on said coil axis.

15. The coil of claim 14, wherein said first and second locking mechanisms cooperate one with the other so that said coil body is detachable from said coil axis together with said cover.

16. The coil of claim 15, wherein said locking mechanisms that serve to fix said coil body and said cover on said coil axis coact in such a way that the two-part coil body can be opened after having been released from the coil axis.

17. A cartridge in a winding-up device configured for winding up a cutting wire configured for cutting through an adhesive bead of a bonded-on pane, said cartridge comprising:

a coil comprising a coil body having at least one opening;

a cutting wire wound onto said coil body and having one end that is secured in said at least one opening of said coil body.

18. The cartridge of claim 17, wherein said coil body comprises a plurality of segments which commonly form an outer contour configured for receiving the wound-up cutting wire and between which at least one space is formed.

19. The cartridge of claim 17, wherein said coil body comprises a plurality of web-shaped segments that are arranged, in radial direction, at equal angular spacings one relative to the other along a circle concentric to the axis of rotation.

20. The cartridge of claim 17, further comprising:

a coil axis on which said coil body is detachably fastened;

a first spring-loaded locking mechanism provided on said coil axis for securing said cover; and

a second spring-loaded locking mechanism provided on said coil axis for fixing said coil body on said coil axis.
