Abstract: A method and apparatus for extrusion of an article is provided. A die assembly can apply flows of thermoplastic material to an array of reinforcing cables to form a composite extrusion. A slider fabric can be bonded to one side of the composite extrusion. After exiting the die assembly, the slider fabric can act to support the extrudate as it passes along an elongate mandrel, which can cause the base of the slider fabric to change shape from a flat profile to the final internal profile of the article. The extruded article can then be cooled to solidify the material. The die can include cooling for the slider fabric and means for promoting penetration of the thermoplastic into reinforcing cables.

In other words, the inner foam section is integral with the outer section, this design has a low density at the center and gradually increases towards outside in a radius state which has a better shock absorption.

Abstract: A roller is structured so that one or a plurality of grooves are recessed on an outer peripheral surface of an outer race in a bearing, a part of a synthetic resin tire integrally adhered to the outer race of the bearing is inserted and welded within a groove on the outer peripheral surface of the outer race in the bearing, whereby a firmer adhesion force can be obtained. Accordingly, a more firmly adhered fitting body is prevented from being peeled off from the outer race of the bearing and the tire and the outer race of the bearing are prevented from separately racing even when the bearing is exposed to a heavy load and rotates at a high speed, that is, the roller is adhered so as to prevent the tire and the bearing from rotating relative to each other.

Abstract: A monoply pneumatic tire has a reinforced sidewall wherein the reinforcement comprises an extra long turn-up which extends into the belt area of the tire. The tire also has a robust chapex in the bead area of the sidewall which has a shape that results from wrapping the turn-up of the carcass ply around the bead of the tire without an apex. The chapex conforms to the shape of the bead. The material in the chapex corresponds in volume substantially to the combined volume of the apex and the chafer of a similarly sized tire.

Abstract: A wheel system for securely mounting a tire thereon. The assembly includes a wheel having a rim with radially outward extending slots. A tire with radially inward extending protuberances mates with the radially extending members for securely mounting the tire to the wheel. The mating of protuberances with the members limits radial deflection and rotational movement of the tire about the rim. Axial movement of the tire relative to the rim is limited by the inner surface of the sidewall of the tire abutting the ends of the radially extending slots. In one embodiment, the wheel is composed of material having elastic properties for absorbing shock.

Abstract: A bicycle wheel assembly includes a hub disposed coaxially in a metal rim. A spoke unit interconnects the hub and the metal rim.

Abstract: A precision wheel, roller and track tread product newly developed consisting of a wheel, roller and track tread material capable of carrying a very heavy load for its size mounted on a new tread locking assembly hub, roller shaft or track tread cleat. The tread locking assembly is designed primarily to bond very difficult to bond materials to a given wheel hub or wheel rim without an adhesive which could be used for commercial, industrial, automotive, and all other purposes where a revolutionary state-of-the-art wheel product is needed. The resultant benefits of the tread alloys with the use of a newly invented tread retention device with super holding power is an inner tube perforated liner mounted over a circular groove derived from a precisionly designed tread locking assembly from specific mathematical, scientific tests and mathematical calculations. These mathematical advantages are a product of groove design dimensions.
