Abstract

In a method for stripping a cable having a multi-layered sheath, first, an initial layer of the sheath of the cable is cut in a stripping device using at least one stripping blade. This is followed by cutting an inner layer of the sheath located opposite the first layer using a laser beam of a laser cutting device. The stripping process is completed by removal of the sheath that was cut using the stripping blade and the laser beam.

First claim

What is claimed is:

1. A method for stripping a cable having a multi-layered sheath comprising the steps of:
at least partly mechanically separating at least one layer of the sheath of the cable; and
at least partly separating another layer of the sheath of the cable by a thermal separation process;
performing the mechanically separating step using at least one stripping blade of a stripping device and performing the thermal separation process step using a laser beam of a laser cutting device;
the method for stripping a cable further comprising:
a) cutting a first layer of the sheath by performing one of the mechanically separating step and the thermal separation process step;
b) cutting an inner layer of the sheath located opposite the first layer by performing another one of the mechanically separating step and the thermal separation step; and
c) removing from the cable a portion of the sheath cut by the at least one stripping blade and the laser beam.

2. The method for stripping a cable according to claim 1 including repeating at least one of the mechanically separating step and the thermal separation step before performing the step c).

3. The method according to claim 1 including, after the step a) is performed, displacing a cut portion of the first layer to form a split exposing the inner layer to be cut.

4. The method according to claim 1 including between performing the steps a) and b), transferring the cable from the stripping device to the laser cutting device using a transfer device.

5. The method according to claim 4 including after the step b) is performed, returning the cable to the stripping device using the transfer device and moving the least one stripping blade of the stripping device to partly or fully remove the portion of the sheath.

6. The method according to claim 5 including forming a slit by the partly removing the portion of the sheath, and introducing into the slit the laser beam of the laser cutting device to cut an additional layer of the sheath.

7. A device for stripping a cable having a multi-layered sheath comprising:
a stripping device with at least one stripping blade; and
a laser cutting device wherein the stripping device and the laser cutting device are each positioned for selectively cutting different layers of the sheath by performing the method according to claim 1 .

8. The device according to claim 7 including a control device connected to the stripping device and to the laser cutting device for controlling the stripping device to cut at least one layer of the sheath and for controlling the laser cutting device to cut at least another layer of the sheath.

9. The device according to claim 7 including a transfer device for transferring the cable between the stripping device and the laser cutting device.

10. The device according to claim 9 wherein the control device automatically feeds the cable from the stripping device to the laser cutting device after the cutting of the at least one layer or feeds the cable from the laser cutting device to the stripping device after the cutting of the at least another layer.
