Roller surface press for continuous drainage of webs of material

摘要

The invention relates to a roller surface press for continuous drainage of webs of material, especially paper webs or cardboard webs, which are used in the pulp and paper industry. The object of the invention is substantially to lengthen the pressing step for increasing the dry content of the web of material, as compared with known roller presses, and to achieve an improvement in the drainage of the web of material, so that a considerable saving of heat and energy results from the associated smaller quantity of water to be evaporated in the dry end. According to the invention, this is to be achieved by arranging a roller surface element for compacting the web of material between working rollers.
