Apparatus for manufacture of sealing closures for a telecommunications cable splice

Claim 1

A low pressure mold comprising two mold halves which when assembled together define a cavity for molding an encapsulation around a splice region of a telecommunications cable, the assembled mold having ends which define an opening for passage of the cable from the cavity and the mold ends defined by ends of the mold halves; a plurality of sealing members, one for each mold half at each end of the mold, each sealing member having a peripheral surface with a plurality of surface regions which are relatively disposed in series around the body of the sealing member, each surface region formed with a respective sealing surface configuration comprising at least one substantially semi-cylindrical, resiliently flexible, sealing surface with the sealing surface configuration being different from one surface region to another; and means for mounting each sealing member upon its respective mold half so that a surface region is in an operating position in which it cooperates with a corresponding surface region of an associated sealing member of the other mold half to seal around a cable extending into the mold, and in respect of each sealing member, said means permitting change in position of the sealing member selectively to locate any associated pair of surface regions in opposition across the mold opening for sealing around cables of different diameters or for sealing around different arrangements of cables extending through the opening.
