Abstract

In this method for fabricating a cable utilizing vinyl sleeving as the outer covering, the apparatus employs a hollow cylindrical container 1 and an inner cylinder 2. The outer cylinder may be longer or shorter than the cable to be fabricated, while the diameter of the inner cylinder 2 is determined by the diameter of the cable. The inner cylinder has a number of holes 3 spaced along its longitudinal axis and is maintained in position inside cylindrical container 1 by separators 4. At each end of cylinder 1 there are a threaded end cap 5 and an adapter 6. After the vinyl sleeving 7 is placed inside the inner cylinder 2, a mechanical expansion tool 8 is inserted inside the adapter 6, forcing the ends of the vinyl against the inside of adapter 6.

Expansion Vacuum Tool

In this method for fabricating a cable utilizing vinyl sleeving as the outer covering, the apparatus employs a hollow cylindrical container 1 and an inner cylinder 2. The outer cylinder may be longer or shorter than the cable to be fabricated, while the diameter of the inner cylinder 2 is determined by the diameter of the cable. The inner cylinder has a number of holes 3 spaced along its longitudinal axis and is maintained in position inside cylindrical container 1 by separators 4. At each end of cylinder 1 there are a threaded end cap 5 and an adapter 6. After the vinyl sleeving 7 is placed inside the inner cylinder 2, a mechanical expansion tool 8 is inserted inside the adapter 6, forcing the ends of the vinyl against the inside of adapter 6. The ends are then rolled back over the outer diameter of adapter 6 and secured in position by clamps 9.

A vacuum pump, not shown, is connected to vacuum ports 10 to produce a vacuum in the area between vinyl sleeving and container 1. This vacuum acting through holes 3 causes expansion of the vinyl sleeving against the inner diameter of the inner cylinder 2. In operation, the mechanical expansion members 8 are first removed, a vacuum applied to vacuum ports 10, the conductors threaded through the sleeving while the vinyl is expanded. The vacuum is then removed, causing the vinyl sleeving to contract to its original size, thus providing a snug fit for the conductors within the cable.
