Abstract
A procedure is described for providing an angled pin seam on a papermakers felt in which a base fabric is woven with a selectively joinable pin seam to form a continuous loop of the base fabric, skewing that base fabric and its seam by displacing one of the lateral edges of the fabric longitudinally of the machine direction relative to the opposed lateral edge while maintaining the machine direction yarns extending substantially in the machine direction, thus skewing the seam relative to the machine direction and to the cross machine direction, and in which batt material is needled into the base fabric while the base fabric is maintained in the skewed condition, whereby the needled batt maintains the fabric in its skewed condition.
