Abstract (en)
[origin: US6197159B1] In a paper making machine for manufacturing a material web (10), such as in particular a paper or cardboard web, the material web (10) to be manufactured is transferred on the surface of a transfer means (24) to a take-off position (30) in the region of which a preferably air-permeable belt (32) having an at least substantially open surface is guided over a take-off roll (34) or the like and takes off the material web (10) from the surface of the transfer means (24). A pressing gap (36) extended in the web running direction (L) is formed at the take-off position (30) with the surface of the transfer means (24, 60) facing the material web (10) being deflected in the region of the extended pressing gap, while forming an at least substantially concave depression (38), and also being pressed by a pressing force intentionally generated in the region of this deflection against the take-off roll (34) in order to thereby assist the take-off of the material web (10) from the surface of the transfer means.
