Claim Text:
1. A permeable press belt for use in a device for dewatering a fibrous web, comprising: a contact side that is in immediate contact with a fibrous web and has a texture adapted to a quality of the fibrous web being produced, said permeable press belt configured to wrap at least partially around a curved surface of a mating element forming a press zone therebetween and to produce a pressing pressure in said press zone when a tensile stress of at least 20 kN/m is applied to said permeable press belt, said permeable press belt having a permeability of at least 20 cfm, said permeable press belt configured to only contact the fibrous web in said press zone, said permeable press belt being configured to maintain said permeability of at least 20 cfm when subjected to said tensile stress without being deformed substantially; and at least a first woven fabric layer comprising at least a plurality of weft threads and a plurality if warp threads, said first woven fabric layer having a transverse seam to connect two ends of said first woven fabric layer, said plurality of warp threads of the respective ends overlapping each other in a region of said seam by at least 150 mm.
