Abstract

Improvements made to the subject of main patent No. 397,233, filed on 22.XI.71, for "A method of molding a hollow rubber article", according to which the inflatable article is first formed into two halves, each being molded half in a female mold cavity from rubber in the uncured state, each half being provided with a locking riser to prevent the displacement of the half; The mold is pressurized and then the two halves of the article are brought into contact and joined together under heat and pressure, said halves being molded in a cross-sectional configuration in which the opening of the female mold cavity is shorter and said cavity is deeper than if the final configuration to be adopted by the article were molded, and the two halves are joined in this state.
