  • 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: 4517737
    Abstract: An apparatus for securing a connector to fabric is disclosed. The connectors are used connect the opposite ends of a fabric belt so as form an endless belt. The connectors are initially in the shape of a V, with legs of unequal lengths. Each leg has an inwardly projecting tip oriented at an accute angle to its respective leg. The connector is secured to the fabric by placing the fabric between the legs and bending them inwardly so that the tips penatrate into the flat woven fabric, thereby securing the connector to it. When the connector is secured to an end of the fabric belt, the apex of the V-shaped connector forms a rounded loop which may then be used to connect it to the opposite end of the fabric belt. The present invention has a pair of primary jaws which press against and actuate a pair of secondary jaws. The connector is secured between the secondary jaws which press against the connector and bend it into the fabric.
