Abstract
Abstract The method of joining two wire cords, particularly two wire tire cords, comprises bending a first wire cord near the end thereof. The end length of the first wire cord is disposed within a heatshrinkable tubing and a second wire cord is bent near the end thereof. The bent regions of the cords are interlocked and the tubing is disposed over the interlocked regions of the cords. Heat is then applied to the tubing to shrink the tubing tightly to join the cords.

Claim 2
Independent Claim
79 words
The method of joining the end lengths of two wire cords comprising: bending a first wire cord near the end thereof; disposing the end length of said first cord within a heatshrinkable tubing: bending a second wire cord near the end thereof; interlocking the bent regions of said cords; disposing said tubing over said interlocked regions of said cords; and applying heat to said tubing to shrink said tubing tightly to join the end lengths of said wire cords.
Claim 3
Dependent Claim
64 words
The method in accordance with claim 1 in which said tubing has a length of approximately 1 1/2 inches, and in which the step of bending said first cord comprises bending said first cord approximately 2 1/4 inches from the end thereof, and in which the step of bending said second cord comprises bending said second cord approximately 3/4 inch from the end thereof.
Claim 4
Dependent Claim
