Beschreibung
Zusammenfassung:	An apparatus and process for the vulcanization of laminar rubber products wherein the process comprises winding onto a drum an unvulcanized laminar rubber product together with a metallic band, applying a counter force to the metallic band as it is being wound up to prestress the wound up layers, applying substantially uniform pressure on the surface of the conducting band at the point where it and the laminar rubber products are being wound onto the drum and then applying electrical current to the wound up electrically conducting band to provide heat for the vulcanization of the wound up laminar layers. The apparatus comprises two parallel drums interconnected by the metallic band which is first wound with the laminar rubber onto one drum and when the vulcanized laminar rubber is removed the metallic band is wound onto the other drum.
