  • Method for manufacturing press felt with seam, press felt, and base fabric
    Patent number: 8308910
    Abstract: A method for manufacturing a press felt with a seam, to a press felt, and a base fabric of a press felt. The base fabric is a one-base structure with machine direction yarns forming seam loops and further machine direction yarns running in the web-side surface layer. The machine direction yarns weave with cross yarns. 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.
