Abstract: 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.

Abstract: The invention relates to an apparatus for the comminution of organic matters, the comminuting unit of which consists of at least one tool provided with axial and/or radial yielding holes and co-acting axially driven stamp. The essential feature of the invention is that a compacting unit (4) before the comminuting unit (5)--in respect of the direction of movement of the organic matter to be comminuted--and a feeding-precompacting unit (3) preceding the compacting unit (4) are arranged, furthermore the feeding-precompacting unit (3) is provided with driven worms (6, 7, 8), the discharge end of which is connected with the large cross sectional end of the bell-mouthed narrowing chambers (18, 19) while its reduced cross sectional end is joined to the pressure chamber (28) of the tools (20, 21).

Abstract: This invention relates to a process and equipment for the crushing of scrap rubber, particularly scrap tire. According to the invention the scrap rubber is forced through small-size openings under a pressure producing the cold yield of the rubber.
