Abstract

A method of manufacturing a fabric seam in a fabric for use as papermachine clothing, the fabric having loops at each of the fabric's transverse ends adapted for interconnection by way of a pintle to make the fabric endless, including the steps of bringing the ends into end-to-end disposition in order to interdigitate the loops, inserting a pintle in the interdigitated loops, heat setting to fix base yarns and the loops of the fabric in place, inserting at least one stuffer yarn, at least a part of which includes a low melt component, into selected void areas in the loops adjacent the pintle, adhering at least one batt layer to the seam by needling, and further heat setting to at least partially melt the stuffer yarn such that it deforms to substantially take on the shape of the void areas at the pintle joint, to bind fibers of the batt needled into the void areas and to bind adjacent yarns of the fabric.
