Abstract:
A paper making machine for manufacturing a material web, comprising:a suction take-off roll having a cylindrical surface;a pressure element comprising one of a soft counter roll and a curved press shoe;a transfer surface comprising one of a flexible press jacket and a transfer belt, the transfer surface having a pressure element engaging side and an opposite web carrying side, the transfer surface being adapted to carry said web, said transfer surface passing through an extended pressing gap, and being deflected from the web carrying side of the cylindrical surface of the take-off roll;the pressure element applying pressure against the take-off roll to define said extended pressing gap between the take-off roll and the transfer surface, the extended pressing gap having a substantially concave shaped depression, wherein the depression is formed via the clyindrical surface of the take-off roll in one of the soft counter roll, the curved press shoe, a web carrying surface of the transfer belt, and a web carrying surface of the flexible press jacket;an air-permeable belt having a substantially open surface, said belt being guided over said take-off roll to pass through said extended pressing gap;wherein said web will transfer from said transfer surface to said air-permeable belt in the region of said extended pressing gap.
