发明名称 In-line pintle loop seam
摘要 An in-line pintle seam for use with a pintle to join adjacent ends of a papermakers belt or the like and a method for producing such a seam. Basically, the seam comprises a spiral and a stuffer pick which are held in place by sewing the face ends of the papermakers belt around the spiral and stuffer pick and then between the center and back layers of the fabric in the case of a three-layer fabric. Once this part of the seaming is completed, the back ends are brought around the spiral and stuffer pick and sewn between the face and center layers of the fabric in much the same way as the face ends. Thus, the spiral and stuffer pick are held to the edge of the fabric by all of the warp yarns. In the case of a two-layer fabric, the ends are sewn back into the fabric between the face and back layers and are pulled through the fabric so that they appear on the back surface of the fabric. In each of the embodiments, all of the sewn back ends, either face or back, do not come out of the fabric in the same line, but are staggered so that a smooth taper and not a ridge is formed.
