PIN SEAMED PAPERMAKERS FELT HAVING A REINFORCED BATT FLAP Abstract of the Disclosure A papermakers felt composed of a pin seam base fabric and a needled batt and having a reinforced batt flap covering the pin seam. The ends of the woven base fabric are provided with interdigitated loops which are connected by a pin to form a pin seam joint. A layer of machine direction yarns are disposed on a face of the base fabric and extend across the joint. A fibrous batt is needled into the base fabric and machine direction yarns. To install the felt on a papermaking machine, the batt is slit at a location spaced from the joint and the portion of the batt be- tween the slit and the joint is pulled away from the base fabric to provide a flap. The machine direction yarns are separated from the base fabric along with the batt and serve to reinforce the batt flap, preventing the flap from tearing away from the felt.
