Abstract (en)

[origin: EP0334201A1] A process and arrangement of a wet press of a paper-making machine where a felt guide roll (16, 18, 20, 38), around which the felt is looped as fully as possible, is periodically moved backwards and forwards at one end with a stroke of 5 to 15 mm at right-angles to the transverse direction of the machine and as far as possible in the direction of the bisector (40) of the felt wrap angle. In this way, the development of a cross-stripe structure resulting from machine vibrations and other influences as the wet felt ages and which would increase the vibrations is substantially prevented. <IMAGE>
