Abstract
A process and apparatus for manufacturing a cable having a composite shield and armor sheath design is disclosed. The process comprises the steps of corrugating a laminated tape formed by bonding a plastic coated aluminum tape to a wider steel tape with one edge of the aluminum tape registering with one edge of the steel tape, forming the corrugated laminated tape around a cable core with the uncovered portion of the steel tape overlapping the registering edges of the laminated tape, and extruding an outer jacket of polyethylene over the corrugated laminated tape.

A process for manufacturing a cable having a composite shield and armour sheath design comprising the steps of:
- (a) bonding a plastic coated aluminum tape to a wider steel tape with one edge of the aluminum tape registering with one edge of the steel tape and the other edge of the aluminum tape spaced inwardly of the other edge of the steel tape to define an uncovered portion of the laminated tape;
- (b) corrugating the laminated tape;
- (c) forming the corrugated laminated tape around a cable core with the uncovered portion of the laminated tape overlapping the registered edges of the laminated tape so as to provide a uniform unwelded overlap;
- and
- (d) extruding an outer jacket of polyethylene over the corrugated laminated tape.
An apparatus for manufacturing a cable having a composite shield and armour sheath design comprising:
- (a) means for bonding a plastic coated aluminum tape to a wider steel tape with one edge of the aluminum tape registering with one edge of the steel tape and the other edge of the aluminum tape spaced inwardly of the other edge of the steel tape to define an uncovered portion of the laminated tape;
- (b) means for corrugating the laminated tape;
- (c) means for forming the corrugated laminated tape around a cable core so that the uncovered portion of the steel tape overlaps the registering edges of the laminated tape so as to provide a uniform unwelded overlap;
- and
- (d) means for extruding an outer jacket of polyethylene over the corrugated laminated tape.
