20220281210 · 2022-09-08 ·

A method of manufacturing a mat is provided. The method involves securing a first layer formed of a polymer within a base die, positioning an intermediate cushion layer on top of the first layer, securing a second layer formed of the polymer to the base die, and securing a perimeter of the first layer to a perimeter of the second layer by radio-frequency welding, so as to envelop the intermediate cushion layer within the first and second layers and thereby form the mat. The first layer has a first surface and an opposing second surface in contact with the base die. The intermediate cushion layer has a first surface and an opposing second surface in contact with the first surface of the first layer. The second layer has a first surface and an opposing second surface in contact with the first surface of the intermediate cushion layer.

PROCESS AND APPARATUS FOR BUILDING TYRES FOR VEHICLE WHEELS AND TYRES OBTAINABLE THEREFROM

In a process for building tyres for vehicle wheels, at least one tread band (9) or other elastomeric component of a tyre (2) is made by applying at least one continuous elongated element (14) according to a plurality of turns (C) around a forming drum (15) rotating around a geometric rotation axis (X) thereof. The continuous elongated element (14) is made by the action of extruding a first material through an extrusion nozzle (16), to form an inner core (33) of said continuous elongated element (14) exiting from an outlet opening (18) of the extrusion nozzle (16). During the extrusion, a second material different from the first material is conveyed around the first material, at the extrusion nozzle (16) and upstream of the outlet opening (18), to form a coating layer (32) which entirely surrounds the inner core (33).

COMPOSITE TREAD WITH TARGETED STIFFNESS GRADIENT AND METHOD OF MAKING

A method for forming a composite tread, the method comprising the steps of: forming a coextruded strip of a first compound and a second compound, wherein the first compound is a tread compound, and the second compound is formed from a second compound, wherein the tread is formed from winding the coextruded strip onto the tire building drum while varying the ratio of the first compound to the second compound

This method includes performing adhesion prevention treatment on uncrosslinked rubber powder, which is a material of the rubber product, to prevent mutual adhesion of the uncrosslinked rubber powder, and sequentially and repeatedly forming by supplying raw rubber powder, on which the adhesion prevention treatment has been performed, and irradiating the supplied portion with an electron beam to crosslink the irradiated portion, so that the crosslinked portions are stacked following a shape of the rubber product.

CHAIN CONTROL DEVICE WITH ELASTOMER FACE OVERMOULDED USING TWO-SHOT INJECTION MOULDING
20220258388 · 2022-08-18 ·

A method of forming a tensioner arm bracket, chain guide, snubber or tensioner arm with two shot injection molding. The tensioner arm bracket, chain guide, snubber or tensioner arm each having a body and a chain sliding face. The body of the tensioner arm bracket, chain guide, snubber or tensioner arm bracket is formed of by a first shot of thermoplastic polymer or thermosetting resin and the chain sliding face is formed by a second shot of thermoset elastomer which is overmoulded onto the body. The body of the component is made of either a thermoplastic or thermosetting resin is fixed to its chain sliding face either by one or more of an anchor point generated by undercuts in the body and/or chemical bonds between the dissimilar materials.

Fiber-reinforced structures
11292213 · 2022-04-05 · ·

A method for manufacturing a fiber reinforced structure includes the following. A mandrel of a first material comprises a hollow interior and an aperture that allows a fluid to enter the interior. A layer of a second material provided on the mandrel includes an uncured resin and fibers. The mandrel and the layer are placed in a mold cavity formed by a mold. A pressurized fluid is introduced into the interior of the mandrel via the aperture to generate a force acting to expand the mandrel outward. The mandrel is heated so that it becomes deformable and expand outward to press the layer against the mold. The layer is heated so that it cures. The mandrel is then heated to a temperature above its melting point of the first material so that it melts, after which it is removed.

Environmentally Friendly Shoe Material and Method of Manufacturing the Same

An environmentally friendly shoe material and method of manufacturing the same is disclosed, wherein the method includes: mixing scraps and a foaming material to provide a shoe material mixture, the scraps including bottle scraps formed by crushing plastic bottles; putting the shoe material mixture into a mold and compression molding the shoe material mixture into the environmentally friendly shoe material; and separating the environmentally friendly shoe material from the mold.
