Abstract
The method used in whole or in part, accelerated but unvulcanized rubber. Forming is done by injection, preserving the properties of plasticity and adhesive power of the rubber, after unmolding and before any vulcanization. The blanks and intermediate products thus fabricated are capable of being integrated, by subsequent successive operations of any type, into more complex assemblies. This method is especially useful in the manufacture of an assembly of a tire bead and an unvulcanized rubber filler strip wherein the filler strip is injected onto the bead to form the assembly.
