expandable chamber and method for manufacturing it for tire vulcanizing apparatus, tire making process, and vehicle wheel tire vulcanizing apparatus

摘要

"EXPANDABLE CHAMBER AND METHOD FOR MANUFACTURING THEM FOR TIRE VULCANIZATION APPARATUS, PROCESS FOR MANUFACTURING TIRES, AND VEHICLE WHEEL TIRES DEVICE". An expandable chamber (1) comprises at least a first layer (8) of butyl material and a second layer (9) of silicone material radially external to the first layer. The first and second layers have a corrugated interface profile (10). ) defining mechanical coupling elements (10a) between the first (8) and the second (9) elastomeric materials. Also disclosed is a process for manufacturing said expandable chamber, as well as a tire molding and vulcanizing apparatus (2) incorporating the chamber.
