ABSTRACT:
The invention is concerned with a base fabric for use in the manufacture of a papermachine press-felt, the base fabric comprising a multi-layer endless woven fabric wherein the machine direction yarns of at least one fabric layer form interdigitated weft loops having a warp yarn therein, and thus define a seam, and wherein at least one further fabric layer exists. The further layer or layers may be continuous throughout the full longitudinal extent of the multilayer fabric, and are slit along the line of the seam after needling of a batt to the base fabric, or may be broken and the weft yarns woven tight about an extreme warp yarn.
