Abstract
Abstract Disclosed is a deformable wire stripper comprising either a single or set of blades fabricated from a deformable material such as a plastic. The material is selected so it will undergo plastic or elastic deformation upon contact with a metal conductor, but yet will penetrate and cause deformation of the wire insulation to be stripped.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
84 words
A process for stripping insulation from wire comprising contacting the insulation with a material exhibiting plastic or elastic deformation greater than that of a conductor with a force sufficient to cause substantial deformation of the insulation via penetration by the material into the insulation; pulling the insulation substantially along the wire axis while maintaining the penetration force, the pull force being sufficient to cause the insulation to sever at the point of penetration whereby the insulation may be stripped without deformation of the conductor.
Claim 2
Dependent Claim
84 words
A process for stripping insulation from wire comprising contacting the insulation with a material exhibiting plastic or elastic deformation greater than that of a conductor with a force sufficient to cause substantial deformation of the insulation via penetration by the material into the insulation; pulling the insulation substantially along the wire axis while maintaining the penetration force, the pull force being sufficient to cause the insulation to sever at the point of penetration whereby the insulation may be stripped without deformation of the conductor.
Claim 3
Dependent Claim
28 words
The process of claim 1 wherein the wire comprises a plurality of twisted insulated conductors, said conductors being both stripped and straightened in one contacting and pulling operation.
Claim 4
Dependent Claim
27 words
The process of claim 1 wherein the wire comprises a plurality of insulated conductors of varying sizes, said conductors being stripped in one contacting and pulling operation.
Claim 5
Dependent Claim
21 words
The process of claim 1 wherein the wire comprises an insulated conductor wherein the insulation is not concentric with the conductor.
Claim 6
Dependent Claim
24 words
The process of claim 1 wherein the deformable material comprises a plurality of deformable blades positioned so as to concentrically deform about the conductor.
Claim 7
Dependent Claim
21 words
The process of claim 1 wherein the deformable material comprises a single blade which contacts the wire positioned over an anvil.
