Abstract
A clipper seam for use with a pintle or lacing unit to join adjacent ends of a papermakers belt or the like. The clipper seam comprises two seam webbings, each of which is woven as a one-piece unit to form a pocket for receiving one of the ends of the papermakers belt. As woven, the pocket is defined by first and second flaps, each of the flaps having an inner surface and an outer surface, the inner surfaces being in a spaced relationship to define the pocket, which is adapted to receive one of the ends of the papermakers belt. Each of the outer surfaces define a stepped, tapered construction. A tongue portion also forms part of the seam webbing. Recessed margins are provided on both the top and bottom surfaces of the tongue, near the distal end or selvage of the tongue. A plurality of clipper hooks adapted to receive one or more pintles are secured to the tongue within the recessed margin. The end of the papermakers belt is secured within the pocket through the use of stitching threads buried in the seam webbing.
