Abstract

The invention concerns a press felt for the pressing region of a papermaking machine and comprises a belt of support material made of one or more fabrics or knits and one layer of fibers deposited at least on the paper side and connected to the belt of support material, the surface of this layer of fibers forming the paper contact-side and a permeable layer being mounted in said layer of fibers between the paper contact-side and the belt of support material. To improve dehydration, the permeable layer is designed to be a blocking layer 7 with a surface covering of 45 to 85 %, the blocking layer 7 comprising transverse, elongated passages 9.
