ABSTRACT:
A wet press papermaker's felt which has a base fabric joined at a pin seam, and which has a batting applied to the felt surface so that the felt is relatively stiff and difficult to join at the pin seam, is provided with a region of increased transverse flexibility through the felt to facilitate the bending of one end of the felt during the threading of a pin through the pin seam. In one embodiment, the region of increased transverse flexibility is formed by a second pin seam in which the batting is uncut at the seam. In another embodiment, this region is defined by a common transverse cross-over point in which the top loop-forming strands go through the fabric to the opposite surface, thereby forming a region of transverse flexibility.
