  • Apparatus for forming an internal socket in a thermosetting elastomeric hose
    Patent number: 5773046
    Abstract: The invention relates to the method and apparatus for producing a cured elastomeric hose having an internal socket or other internal configuration formed therein. The invention also relates to the product produced according to the method and the apparatus. Cured elastomeric hose can be formed having an internal socket by mounting the hose on a mandrel assembly having the desired internal configuration formed therein. An end forming cap assembly is selectively mounted on the hose and mandrel assembly, tightly engages the hose and forces the hose to assume the shape of the mandrel assembly. The hose is cured and then the end forming cap is removed from the hose through the use of an air removal tool. The product produced according to this invention is suitable to receive a wide variety of articles such as an anti-splashback valve or a molded thermoplastic connector.
