Abstract
The invention relates to a device (1) for producing an electrical cable (2) which has a cable film (20). The device has a film working module (9) for reducing the mechanical loadability of the cable film (20) at a crack position (PR) which is provided along a cable centre axis (M). The film working module (9) has a round blade (33) in order to cut into at least one outer layer, which is remote from the cable centre axis (M), of the cable film (20) at the crack position (PR).
Claims30
A device for producing an electrical cable which has a
- cable film, said device comprising a film processing module for reducing a mechanical load-bearing capability of the cable film at a tearing position (Pr) provided along a cable central axis (M),
- wherein the film processing module has a circular knife for scoring at the tearing position (Pr) an at least one external layer of the cable film that faces away from the cable central axis (M);
- and
- wherein the film processing module comprises a gate positioned along the cable central axis (M) to limit a cutting depth of the circular knife by guiding the circular knife about the cable along the gate.
A method for producing an electrical cable having a cable film, the method comprising a step of using a circular knife to score, at a tearing position (Pr) provided along a cable central axis (M), an at least one external layer of the cable film that faces away from the cable central axis (M), wherein a cutting depth of the circular knife is limited by a gate positioned along the cable central axis (M), the circular knife being guided about the cable along the gate, and
- wherein a mechanical load-bearing capacity of the cable film is reduced at the tearing position (Pr).
A device for producing an electrical cable which has a cable film, said device comprising a film processing module for reducing a mechanical load-bearing capability of the cable film at a tearing position (PR) provided along a cable central axis (M),
- wherein the film processing module has a circular knife for scoring at the tearing position (PR) an at least one external layer of the cable film that faces away from the cable central axis (M);
- and
- wherein the film processing module is configured to guide the circular knife along a gate positioned along the cable central axis (M), thereby forming a cutting depth limitation.
