摘要： What is proposed is a process for joining conveyor belts which contain metal inserts by vulcanization, and also a corresponding vulcanizing press. In order to achieve a temperature profile during the joining process which is more uniform over the material thickness in the joining region, in the proposed process - the belt portions to be joined are arranged between a first crossbeam leading through underneath the belt underside (1B) and a second crossbeam leading over the belt top side (1A), - the crossbeams are pressed against one another by a pressure-exerting device, with the interposition of the belt portions, - the belt material is heated up to vulcanization temperature by at least one heating device arranged in the region of the belt underside and/or the belt top side, wherein the heating device is an electrical inductor (12) which generates a magnetic field (F). Said inductor is arranged between the two crossbeams and in such a manner in relation to the belt material that, after the inductor (12) has been activated, the metal inserts (2) of the belt portions to be joined are located in the magnetic field (F) thereof.
