摘要

An open ended papermaker's fabric woven from longitudinal and transverse thread systems and including a plurality of seam loops at each end. Two additional transverse threads are interwoven with the longitudinal thread system in the seam zone. The crossover points of the two additional transverse threads occur at a transition between paired paper and machine side threads of the longitudinal thread system which are separated in the transverse direction by at least three top layer longitudinal threads.
