A continuous material press for the production of material sheets made of substances which require a high pressure and an intensive thickness reduction during the pressing process, with the press including a heated/cooled and driven central drum, and a circulating endless steel belt tensioned around the central drum, with the material to be pressed being guided and pressed between the shell surface of the central drum and the steel belt. An additional stationary pressing device comprised of elastic steel belt sections is located outwardly of the endless steel belt and is mounted in tension to variably increase the pressure on the endless steel belt and thus on the material. An opening is formed in the steel belt section mounted in which is a pipe for delivering compressed air or water vapor to interface on the endless steel belt and the stationary steel belt section, the compressed air or water vapor forming a lubricating film for reducing friction.

Continuously operating material press with lubricating film for reducing

A continuously operating material press comprising temperature-controllable and drivable central drum 1 and a tensioned endless steel belt which passes around a major portion of the surface of the central drum and is supported by at least two guide drums and a tensioning drum. An increase in the pressure acting on a strip of material which is guided between the steel belt and the surface of the central drum is achieved by providing an additional pressing means which comprises a roller chain and an additional high-tensile steel belt supported by the chain. Both the roller chain and the additional steel belt are connected to a support structure for the central drum either directly or through the intermediary of tensioning devices.

Continuously operating material press

An endless belt, for apparatus for continuously hot pressing webs of material by pulling the belt against the periphery of a heated rotatable drum with the web interposed therebetween, comprising a layer of butyl rubber bonded to a fabric of steel wires, a textile layer adhered to the butyl rubber and a layer of silicon rubber adhered to the textile layer. In manufacture the fabric of steel wires is encased in the butyl rubber, the textile layer is adhered to the butyl rubber and the composite article is vulcanized. After vulcanization, the silicon rubber layer is adhered to the textile layer and the composite article thus formed again vulcanized.
