Abstract

A press felt for the press area of a paper machine has a supporting material web made of one or more woven fabrics or knitted fabrics and a fibre layer applied at least to the paper side and associated with the supporting material web, the surface of which forms the paper contact side and in which a permeable layer is arranged between the paper contact side and supporting material web. To improve the dewatering power, the permeable layer is designed as a barrier layer (7) having a surface covering of 45% to 85%, the barrier layer (7) having elongated passage openings (9) aligned in the transverse direction. <IMAGE>
