Abstract
Abstract A length of severed insulation is stripped from a conductor by applying pressurized fluid between the conductor and the insulation to generate a fluid bearing therebetween and by then moving the insulation from the conductor along the fluid bearing. The insulation may be severed by (1) cutting partially through the insulation and applying pressurized fluid between the conductor and the insulation to expand and rupture the insulation at the cut; by (2) using the pressurized fluid to expand the insulation against a cutting blade; or by (3) using a precision cutting technique without the application of pressurized fluid.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
110 words
A method of stripping a severed length of jacket from a cord that includes at least one insulated conductor, the method comprising the steps of: clamping the cord at first and second points on the cord, the first point being proximate to one end of the cord and the second point being proximate to the point of severance on the side opposite to the first point; applying pressurized fluid between the jacket and the insulated conductor to generate an air cushion between the severed length of jacket and the insulated conductor; and displacing the severed length of jacket along the air cushion to strip the severed jacket from the cord.
Claim 2
Independent Claim
110 words
A method of stripping a severed length of jacket from a cord that includes at least one insulated conductor, the method comprising the steps of: clamping the cord at first and second points on the cord, the first point being proximate to one end of the cord and the second point being proximate to the point of severance on the side opposite to the first point; applying pressurized fluid between the jacket and the insulated conductor to generate an air cushion between the severed length of jacket and the insulated conductor; and displacing the severed length of jacket along the air cushion to strip the severed jacket from the cord.
Claim 3
Independent Claim
60 words
A method of stripping a predetermined length of insulation from a conductor, comprising the steps of: severing the insulation a predetermined distance from one end of the conductor; forcing a pressurized fluid between the insulation and the conductor to generate a fluid bearing between the insulation and the conductor; and pulling the insulation from the conductor along the fluid bearing.
Claim 4
Independent Claim
60 words
A method of stripping a predetermined length of insulation from a conductor, comprising the steps of: severing the insulation a predetermined distance from one end of the conductor; forcing a pressurized fluid between the insulation and the conductor to generate a fluid bearing between the insulation and the conductor; and pulling the insulation from the conductor along the fluid bearing.
Claim 5
Dependent Claim
70 words
A method of stripping a predetermined length of insulation from a conductor as set forth in claim 2, wherein severing the insulation comprises: moving a cutting blade transversely across the insulation at a predetermined distance from the end of the conductor to cut partially through the insulation so that expansion of the insulation by the application of the pressurized fluid ruptures the insulation at the cut to sever the insulation.
Claim 6
Dependent Claim
65 words
A method of stripping a predetermined length of insulation from a conductor as set forth in claim 2, wherein severing the insulation comprises: positioning a cutting blade transversely across the insulation at a predetermined distance from the end of the conductor so that expansion of the insulation by the application of the pressurized fluid forces the insulation against the cutting blade to sever the insulation.
Claim 7
Dependent Claim
92 words
A method of stripping a predetermined length of insulation from a conductor as set forth in claim 2, wherein severing the insulation comprises: moving a cutting blade transversely across the insulation at a predetermined distance from the end of the conductor to cut partially through the jacket; moving the cutting blade relative to the length of the insulated conductor to bear against the cut portion of the insulation and separate the insulation thereat; and guiding the moving cutting blade vertically relative to the conductor to preclude the blade from cutting the conductor.
Claim 8
Independent Claim
165 words
A method of severing and stripping a jacket from a cord that includes a plurality of insulated conductors, the method comprising the steps of: clamping the jacket at first and second points, the first point being proximate to an end of the cord and the jacket being deformed by the clamping thereat to form a passageway between the jacket and the insulated conductors; moving a cutting blade transversely across the jacket between the clamping points at a predetermined distance from the end of the cord to cut partially through the jacket; applying pressurized fluid to the end of the cord between the insulated conductors and the jacket and past the passageway to expand the jacket between the end of the cord and the second clamping point to thereby rupture the jacket at the cut and to form a fluid bearing between the jacket and the insulated conductors; and displacing the ruptured end length of jacket along the fluid bearing away from the second clamping point.
Claim 9
Independent Claim
165 words
A method of severing and stripping a jacket from a cord that includes a plurality of insulated conductors, the method comprising the steps of: clamping the jacket at first and second points, the first point being proximate to an end of the cord and the jacket being deformed by the clamping thereat to form a passageway between the jacket and the insulated conductors; moving a cutting blade transversely across the jacket between the clamping points at a predetermined distance from the end of the cord to cut partially through the jacket; applying pressurized fluid to the end of the cord between the insulated conductors and the jacket and past the passageway to expand the jacket between the end of the cord and the second clamping point to thereby rupture the jacket at the cut and to form a fluid bearing between the jacket and the insulated conductors; and displacing the ruptured end length of jacket along the fluid bearing away from the second clamping point.
