Abstract

A method for removing insulation from inner conductors of a cable having a first section with a cable sheath removed and a second section with the cable sheath not removed utilizes a stripping device to perform the following steps: inserting the first section between a first rotatable roller and a second rotatable roller of the stripping device; moving the first roller and/or the second roller toward each other to clamp the first section between the rollers; moving the cable in a first direction that moves the second section away from the rollers; moving the cable in a second direction opposite the first direction that moves the second section toward the rollers; moving stripping blades toward the first section to cut into the insulation of the inner conductors; and moving the cable in the first direction to remove at least part of the insulation from the inner conductors.

First claim

What is claimed is:

1. A method for removing insulation from a plurality of inner conductors inside a sheath of a cable comprising the steps of:
providing a stripping device having stripping blades and first and second rollers, each of the first and second rollers being rotatable about a respective axis and being movable towards and away from each other;
providing the cable with a first section in which the cable sheath is removed and a second section in which the cable sheath is not removed;
inserting the first section between the first and second rollers;
moving at least one of the first roller and the second roller such that the first and second rollers clamp the first section between the first and second rollers;
moving the cable in a first direction such that the second section moves away from the first and second rollers while the first section is clamped between the first and second rollers;
moving the cable in a second direction opposite the first direction such that the second section moves toward the first and second rollers while the first section is clamped between the first and second rollers;
moving the stripping blades towards the first section such that the stripping blades cut into the insulation of the inner conductors; and
moving the cable in the first direction to remove at least part of the insulation from the inner conductors.

2. The method according to claim 1 wherein a pressure with which the first and second rollers clamp the first section is increased after the cable has been moved in the first direction and before the cable is moved in the second direction.

3. The method according to claim 1 wherein the stripping blades and cutting blades for cutting the cable are included on a cutter head, and including a step of moving the cutter head in a direction perpendicular to the first direction to arrange the first section between the stripping blades.

4. The method according to claim 1 wherein during the clamping of the first portion between the first and second rollers, the first and second rollers are each moved toward one another.

5. The method according to claim 1 wherein a pressure with which the first and second rollers clamp the first section is a function of a distance between the first and second rollers.

6. The method according to claim 1 wherein a pressure with which the first and second rollers clamp the first section is pneumatically adjusted independently of a distance between the first and second rollers.

7. The method according to claim 1 including moving the cable multiple times alternately in the first direction and the second direction while the first section is clamped between the first and second rollers.

8. The method according to claim 1 including moving the cable alternately in the first direction and the second direction until the inner conductors are arranged in one plane.

9. A stripping device for removing insulation from inner conductors inside a sheath of a cable having a first section in which the cable sheath is removed and a second section in which the cable sheath is not removed, the stripping device comprising:
a rotatable first roller and a rotatable second roller adapted to clamp the first section of the cable between the first roller and the second roller;
a moving device for moving the cable in a first direction and then in a second direction opposite to the first direction while the first section is clamped between the first and second rollers;
wherein during movement of the cable in the first direction, the second section is moved away from the first and second rollers and during movement of the cable in the second direction, the second section is moved toward the first and second rollers; and
stripping blades for removing the insulation of the inner conductors, wherein the stripping blades are arranged to cut into the insulation of the inner conductors whereby the insulation is removed from the inner conductors when the cable is moved in the first direction.

10. The stripping device according to claim 9 including a cutter head having the stripping blades and cutting blades thereon, wherein the cutter head is movable in a direction perpendicular to the first direction such that the first section extends between the stripping blades.

11. The stripping device according to claim 9 wherein the first and second rollers are movable towards one another in opposite directions of movement to clamp the first section.

12. The stripping device according to claim 9 wherein a pressure with which the first and second rollers clamp the first section can be increased while the first section is clamped between the first and seconds rollers by moving at least one of the first and second rollers, wherein the pressure with which the first and second rollers clamp the first section is a function of a distance between the first and second rollers.

13. The stripping device according to claim 9 wherein a pressure with which the first and second rollers clamp the first section can be increased by an actuator coupled to at least one of the first and second rollers without substantially changing a distance between the first and second rollers while the first section is clamped between the first and second rollers.

14. The stripping device according to claim 9 wherein the moving device is adapted to move the cable multiple times alternately in the first direction and the second direction while the first section is clamped between the first and second rollers.

15. The stripping device according to claim 9 wherein the moving device is adapted to move the cable alternately in the first direction and the second direction until the inner conductors are arranged in one plane.
