Patent number: 5609242Abstract: A steel wire or cable conveyor belt with improved penetration and rip resistance is made by plying up a series of rubberized longitudinal steel cables or wires to give a core, placing a ply of rubberized woven fabric such as polyaramide or nylon over the core, such as a tire breaker ply or plies over the core, then a ply of rubberized closely placed, essentially in contact wire, preferably of heavy tire ply cable, such as an earth mover ply, cut to cover the core in transverse direction to allow the steel wire or cable to be positioned perpendicular over the longitudinal steel wire or cable, apply a cover stock ply over the transversely positioned short wire or cable. The underside of the longitudinal steel wire or cable core has a rubberized woven fabric positioned there beneath and a rubberized pulley ply beneath the woven fabric ply.

Patent number: 4836513Abstract: A hydraulically damped anti-vibration mount has a flexible diaphragm, an outer metal casing, an annular rubber spring and an inner metal portion, together defining a cavity filled with a fluid. A damper plate divides the cavity into an upper chamber and a lower chamber which are in fluid communication through a damper channel located within the damper plate. A cup-shaped bumper attached to the inner metal portion and extending axially inward into the upper chamber has a radially outwardly extending flange located at an end distal to the inner metal portion. A flexible flap in the shape of an "h" or a wishbone extends radially outwardly from the flange toward the outer metal casing to within a clearance of about 1 mm to about 6 mm to inhibit the dynamic rate of the mount.Type: GrantFiled: March 16, 1988Date of Patent: June 6, 1989Assignee: The Goodyear Tire & Rubber CompanyInventors: Robert H.

Patent number: 4767244Abstract: 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.Type: GrantFiled: July 10, 1987Date of Patent: August 30, 1988Assignee: The Goodyear Tire & Rubber CompanyInventor: Paul J. Peterson

Patent number: 4767658Abstract: Fully cured thermoset ethylene-propylene rubber sheets having integral thermoplastic adhesive strips molded along the lateral edges are produced using a manufacturing method where the strips are applied prior to vulcanization of the rubber sheeting. The factory applied adhesive strip is non-tacky and dry but is activated by heat to securely bond the ethylene-propylene rubber sheets together in an overlap splicing procedure. A method of using the integral adhesive rubber sheeting for single-ply rubber roofing membrane or pond liners is also disclosed. Instantaneous attainment of maximum seam strength, water tightness and consistency of the seams are advantages over conventional solvent-based adhesive methods.Type: GrantFiled: January 20, 1987Date of Patent: August 30, 1988Assignee: The Goodyear Tire & Rubber CompanyInventor: Harold K.

Patent number: 4753699Abstract: For making hose for industrial use by winding a plurality of tapes helically about an elongated metal surface core, a mass of warm uncured curable rubber compound is converted to continuous running lengths of parallel tapes by calendering, cooling and slitting the same. A multiplicity of bobbins are prepared, each having a substantial length of one of the tapes thereon. The core is supported at suitably spaced intervals along its length. The core is rotated, and at least one of the bobbins is concurrently carried in a direction parallel to the core at a rate commensurate with the helical winding desired. A tape from a first bobbin is wound about the core, and then tape is wound in like manner about the core, one at a time from successive bobbins, to complete the structure of the hose on the core. The core and the hose so constructed are transferred to an autoclave of length accommodating the length of the core, and the hose is cured in the autoclave.Type: GrantFiled: August 22, 1984Date of Patent: June 28, 1988Assignee: The Goodyear Tire & Rubber CompanyInventor: Alfio Deregibus

Patent number: 4749345Abstract: A method of manufacturing a beadless flexible member for an airspring having a fully molded non-tubular shape. An axially segmented mold with tapered circular end bores is used with conically tapered end plugs which sealingly compress an uncured preform of the flexible member between the conical plugs and the tapered circular end bores. Compressed fluid is injected into the interior of the preform to radially expand it to the desired molded shape. At a rate determined by the radial expansion of the preform, the annular segments of the mold are axially moved together to accommodate the axial foreshortening of the preform during its radial expansion. After full axial closure of the mold, heat and pressure are applied to vulcanize the preform. The beadless, fully molded flexible member may be used for airsprings requiring zero pressure roll capability.Type: GrantFiled: March 13, 1987Date of Patent: June 7, 1988Assignee: The Goodyear Tire & Rubber CompanyInventors: Ivan J. Warmuth, Carl K. Safreed, Jr.
