Vulcanising apparatus for vulcanizing a rubber article, as well as a method for forming and vulcanizing a rubber article, in particular of a vehicle tire in a vulcanizer

摘要

The tool has a heated bead forming ring and a heated curing bag(13) which contact the product surface, in particular the sidewall of a tire. At the area of contact of the tool part the heated ring surface(12) has grooves(20). The grooves extend from the heating surface into a chamber(19) for holding excess rubber(22). An Independent claim is included for a process for molding and vulcanizing a rubber product, in particular a pneumatic vehicle tire in which initial pressurized contact is made between the unvulcanized tire and a heated curing bag(13) and a heated bead forming ring(11) forcing excess rubber(22) through grooves(20) in the tool part into an overflow chamber(19).
