METHOD FOR MANUFACTURING PRESS FELT WITH SEAM, PRESS FELT, AND BASE FABRIC

摘要

The invention relates to a method for manufacturing a press felt with a seam, to a press felt, and further to a base fabric of a press felt. The base fabric (1) is a one-base structure with machine direction yarns (10a, 10b) forming seam loops (12) and further machine direction yarns (7) running in the web-side surface layer (A). The machine direction yarns weave with cross-yarns (8). The yarn ratio of the surface layer machine direction yarns to the intermediate layer and further the bottom layer machine direction yarns is at least 2:1:1. In addition, the surface layer machine direction yarns have a long run and their cross-sectional area is smaller than the yarns forming the seam loops.
