Abstract
Abstract Making a gas pressurizable closure for a splice region of a telecommunications cable in which plastic ends of the closure are molded in position by locating molds for the ends in axially spaced-apart positions one at each side of the splice region. While the cable is allowed to follow its natural path through and between the molds, the molds are held fixed relative to one another and aligned with one another and the plastic ends are molded. A shroud means of the closure is then located between and sealed to the plastic ends with the cable still following its natural path.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
165 words
A method of a gas pressurizable closure for a splice region of a telecommunications cable in which the closure has axially spaced molded plastic ends and a bridging shroud means, the method including molding the ends in position by disposing two molds for the ends in axially spaced-apart positions, one at each side of the splice region; and with the cable allowed to follow the path it would follow in the absence of the molds through and between the molds, holding the molds fixed relative to one another in desired positions aligned with one another that the spaced ends will occupy in the finished closure, and molding the ends while holding the molds in said positions and locating the shroud means in position extending between the plastic ends and sealed thereto with the cable still following said path, such that there is no twisting force imposed upon the plastic ends which would tend to destroy the seal between the plastic ends and the shroud means.
