PROCESS FOR FORMING RUBBER TUBE EXTREMITIES DURING THEIR VULCANIZATION ON A MANDREL AND DEFORMABLE TOOLING FOR EXECUTION OF THE PROCESS

摘要

The process uses as tooling a radially deformable skirt (4), made of vulcanised rubber, which grips around the end of the preform under the effect of the sole circumferential elasticity of its corolla (11), the release of the part after vulcanisation being performed by a simple axial thrust (P) on the said corolla (11) and a rolled-up position (13) of the radially deformable skirt (4) permitting the production operations. ……
