ABSTRACT:
The invention relates to a method and apparatus for manufacturing bands of elastomeric or thermosetting material of the type used in making impervious seals and gaskets. The process consists in molding or injecting at ambient temperature the elastomeric or thermosetting material in the viscous state into a molding cavity on a support which, compared to the material being deposited, has an adherence that is greater than that of the molding cavity. Subsequently, the deposited material is vulcanized or polymerized into the desired band configuration.
