  • Patent number: 5875822
    Abstract: An on-machine-seamable (OMS.RTM.) papermakers' fabric produced by modified endless weaving includes machine-direction (MD) and cross-machine direction (CD) yarns. The MD yarns are plied/twisted yarns, and weave continuously back-and-forth between the two widthwise edges of the fabric, each time forming a seaming loop at one of the two widthwise edges. A seaming spiral, a monofilament spiral preferably extruded from a polyamide resin, is attached to the seaming loops at each of the two widthwise edges. The two seaming spirals are used to join the fabric into endless form with a pin seam. In this way, an OMS.RTM. papermakers' fabric, having plied/twisted yarns in the machine direction is provided with monofilament joining means which maintain proper orientation and shape for the ready pin seaming of the fabric on a papermachine.

  • Patent number: 5669115
    Abstract: A mechanical belt fastener for joining the open ends of a conveyor belt has a first row and a second row of legs arranged parallel to one another with a distance between the rows on both sides of a folding area. The legs are bendable in the folding area to form loops and have bent tips that penetrate material of the belt. Legs of the two rows extending lengthwise on both sides of the folding area and the legs in the first row in a first section extend up to a continuous first strip that extends transversely with respect to lengths of the legs. The legs of the first section are attached to the first strip, and the legs adjacent to one another in each row are of different lengths relative to the folding area. Each two legs of the second row are connected through a second strip with one another to form leg pairs and the second strip is interrupted in a direction of immediately adjacent leg pairs of the second row.

  • Patent number: 4996750
    Abstract: A wire belt fastener is formed from a piece of wire to have a wire body having a pair of arms joined by a U-shaped hinge pin section. The ends of the wire are flattened to form wide areas having grooves to receive the head and the bent ends of a staple. The fasteners are aligned in a juxtaposed array by a connector wire or rod extending normal to the arms and spanning across a series of belt fasteners to space them evenly to receive interdigitated hinge loops of another array of belt fasteners. A belt stop comprising a projecting piece of wire is secured to an inner surface of one arm of the wire belt fastener to be abutted by the cut belt end to limits its insertion into the gap between the arms of the wire belt fastener. To reduce the lateral width of the belt fasteners and to place more metal in the splice, the wire cross-section at the hinge loop is substantially oblong with flat faces of adjacent, intermeshed fasteners being side by side.

    Abstract: A fastener and fastener assembly for coupling the ends of a conveyor belt to form a continuous belt where the preferred embodiment is a belt fastener having an upper and lower arm connected by a loop, and having a belt stop positioned to limit insertion of a conveyor belt end. The assembly utilizes a first and second set of fasteners mounted on opposite belt ends which intermesh to define a hinge passage for a hinge pin to couple the belt ends together. The reach-back of the belt ends into the belt fasteners is maximized as the belt stops are aligned with their belt loops and positioned to abut the belt end at a location where the exterior surface of a belt loop of the opposite belt fasteners is engaging or nearly engaging the belt end.

  • Patent number: 4476902
    Abstract: 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.
