Claims
- 1. A winding device having a rotational axis and two side walls arranged substantially parallel to each other and perpendicular to the rotational axis, each side wall being provided with two slits which extend from the middle portion of the sidewall from near the rotational axis continuing substantially parallel to the edges of the side wall out to both extreme ends of each side wall and a supply of bolts arrnged in relation to both extreme ends of the two side walls in a feeding arrangement whereby the bolts have a smaller diameter than the width of the slits and a greater length than the distance between the two side walls.
- 2. The winding device of claim 1 wherein the rotational axis has a removable central bolt which bolt is provided with a longitudinal aperture.
- 3. The winding device of claim 2 wherein both extreme ends of each side wall are provided with a protruding end which is longer than the radius of the bolts and the four protruding ends are arranged rotationally-symmetrically to the rotational axis of the winding device and mirror-symmetrically to a plane which is parallel to the side walls.
- 4. The winding device of claim 2 wherein each side wall is provided at its extreme ends with lateral extensions which are perforated.
- 5. The winding device of claim 4 wherein the support of bolts consists essentially of one or more storage devices containing the bolts and which storage devices have a smaller width than the distance between the two adjacent lateral extensions of each side wall.
- 6. The winding device of claim 1 wherein the bolts have
- (a) a cylindrical portion having a smaller diameter than the width of the slits and a greater length than the distance between the two side walls and
- (b) an end portion,
- whereby a substantially circular groove is located on the circumference of the bolts between the cylindrical portion and the end portion of each and the rotational axis has a removable central bolt which is provided with a longitudinal aperture.
- 7. The winding device of claim 6 wherein each side wall is separated by the two slits into four branches and one of two branches separated by a slit is provided with a protruding end which is longer than the radius of the bolts.
- 8. The winding device of claim 7 wherein each side wall is provided at its extreme ends with lateral extensions which are perforated.
- 9. The winding device of claim 8 wherein the supply of bolts consists essentially of one or more storage devices containing the bolts and which storage devices have a smaller width than the distance between the two adjacent lateral extensions of each side wall.
- 10. The winding device of claim 6 wherein each side wall is provided at its extreme ends with lateral extensions which are perforated.
- 11. The winding device of claim 10 wherein the supply of bolts consists essentially of one or more storage devices containing the bolts and which storage devices have a smaller width than the distance between the two adjacent lateral extensions of each side wall.
- 12. The winding device of claim 1 wherein the bolts have
- (a) a cylindrical portion having a smaller diameter than the width of the slits and a greater length than the distance between the two side walls and
- (b) an end portion,
- whereby a substantially circular groove is located between the cylindrical portion and the end portion of each.
- 13. The winding device of claim 1 wherein each side wall is provided at its extreme ends with lateral extensions which are perforated.
- 14. The winding device of claim 1 wherein both extreme ends of each side wall are provided with a protruding end which is longer than the radius of the bolts and the four protuding ends are arranged rotationally-symmetrically to the rotational axis of the winding device and mirror-symmetrically to a plane which is parallel to the side walls.
- 15. The winding device of claim 14 wherein each side wall is provided at its extreme ends with lateral extensions which are perforated.
- 16. The winding device of claim 15 wherein the supply of bolts consists essentially of one or more storage devices containing the bolts and which storage devices have a smaller width than the distance between the two adjacent lateral extensions of each side wall.
- 17. The winding device of claim 1 wherein the supply of bolts consists essentially of one or more storage devices containing the bolts and which storage devices have a smaller width than the distance between the two adjacent lateral extensions of each side wall.
