Abstract:
1. A method for vulcanizing or cross-linking a section of a shaped body consisting of rubber mixtures under pressure and increased temperature, the method comprising: placing a section of the shaped body which includes the section to be vulcanized or cross-linked on an open bed of fine-grained flowable bulk material which serves as a positive support for the shaped body; reciprocating or vibrating the bed of bulk material or the shaped body, or both, so that the bulk material is brought into a uniformly tight contact with the surfaces of said section of the shaped body including the section to be vulcanized or cross-linked; thereafter, heating the shaped body or the bulk material, or both, to the increased vulcanization or cross-linking temperature; and pressing only the section of the shaped body including the section to be vulcanized or cross-linked against the positive support of the bulk material until the vulcanization process is completed.
