  • Patent number: 4715106
    Abstract: This invention uses a unique tubular cutting tool in a method for separating individual cables from the elastomeric body of a cable-type conveyor belt. The tool bores a cylindrical path through the elastomeric body coaxial with the individual longitudinal reinforcement cables. A transverse cut is then made across the belt width which just intersects the cylindrical paths which have been made around the cables. The elastomeric material can then be removed leaving only the cables exposed. The prepared belt end is then ready for application of a mechanical or vulcanized splice. The tubular cutting tool features both circular and axial cutting edges. The tool can be utilized in a hand drill to allow on-site splice preparation of the conveyor belt.

  • Patent number: 4671403
    Abstract: A flexible hinge-pin for coupling two complementary rows of fastening staples on the opposite ends of closed-loop conveyor belt or the like comprises a flexible central core such as a steel cable. The core is surrounded successively by an intermediate plastic sheath and a tubular outer jacket formed by twisting one or a number of strands of wire, either in the same direction of twist as the core or in the opposite direction. The intermediate sheath can be of plastic material filled with grease which is capable of flowing under the action of the relative movements of the hinge-pin components at the time of flexural deformation of the pin in order to ensure that a fraction of the grease spreads over the surface of the pin.

  • Patent number: 4582505
    Abstract: The invention relates to a connector element for the belt ends of conveyor elts, which embraces the belt end with its shanks in a U-shape while forming an eye loop. The connector element has openings in its shanks for receiving staple-like securing means, as well as projections on the sides of the shanks facing each other. These projections extend perpendicularly to the longitudinal direction of the shanks, and can be pressed into the belt surface. At least two projections are arranged on each shank, one behind the other as viewed in the shank's longitudinal direction. The projections protrude sideways beyond the shanks, and their free ends form an intermeshing connection of the shanks of neighboring connector elements. These projections may extend at a right angle or at a slant across the length of the respective shank.
