Abstract

A method of removing a foil shield from a cable. The method includes: positioning the cable proximate a heating source; heating the foil shield in a designated area to weaken the foil shield; and removing an outer insulation of the cable and the foil shield after the foil shield has been heated.

First claim

The invention claimed is:

1. A method of removing a foil shield from a cable, the foil shield having a metal component and a plastic component, the method comprising:
positioning the cable proximate an induction heating source;
heating the foil shield in a designated area to soften or melt the plastic component and weaken the foil shield;
allowing the plastic component of the foil shield to cool and adhere to an outer insulation of the cable in the designated area; and then
removing the outer insulation of the cable and the foil shield after the foil shield has been heated.

2. The method as recited in claim 1 , wherein the metal component is aluminum and the plastic component is poly-ethylene terephthalate.

3. The method as recited in claim 1 , further comprising heating the metal component of the foil shield in the designated area by induction heating above a melting point of the plastic component.

4. The method as recited in claim 1 , wherein the plastic component in the designated area is vaporized.

5. The method as recited in claim 1 further comprising varying a frequency of the induction heating source to control a depth of heating.

6. The method as recited in claim 1 , wherein the foil shield in the designated area is heated through the outer insulation.

7. The method as recited in claim 1 , further comprising exposing a portion of the foil shield in the designated area to allow the plastic component to vaporize.

8. The method as recited in claim 1 , wherein the induction heating source is a heating coil which extends about the circumference of the cable in the designated area.

9. The method as recited in claim 1 , wherein the induction heating source is positioned into a machine that cuts the cable to length.

10. The method as recited in claim 1 , further comprising varying power applied to the induction heating source.

11. The method as recited in claim 1 , further comprising varying an amount of time the induction heating source is powered.

12. A method of removing a foil shield from a cable, the foil shield having a metal component and a plastic component, the method comprising:
positioning the cable proximate an induction heating source;
heating the metal component of the foil shield by induction heating through outer insulation of the cable in a designated area to soften or melt the plastic component and weaken the foil shield;
removing the induction heating source;
allowing the plastic component of the foil shield to cool and adhere to the outer insulation in the designated area prior to the outer insulation of the cable and the foil shield being removed from the designated area;
cutting the outer insulation of the cable in the designated area; and
removing the outer insulation of the cable and the foil shield from the designated area.

13. The method as recited in claim 12 , wherein the foil shield in the designated area is heated through the outer insulation.

14. The method as recited in claim 12 , further comprising exposing a portion of the foil shield in the designated area by cutting the outer insulation.

15. A method of removing a foil shield from a cable, the foil shield having a metal component and a plastic component, the method comprising:
positioning the cable proximate an induction heating source;
exposing a portion of the foil shield in a designated area by cutting an outer insulation of the cable;
heating the foil shield in the designated area to soften or melt the plastic component and weaken the foil shield;
removing the heating source;
allowing the plastic component of the foil shield to cool and adhere to the outer insulation in the designated area; and then
removing the outer insulation of the cable and the foil shield from the designated area.
