Abstract: A tube tire for avoiding damage to a tube in charging a sealant, and for preventing the sealant from plugging an air valve of the tube. A first tube half and a second tube half have the same side and circular cross sections are joined together as raw rubber, and then vulcanized, thereby forming a tube consisting of the two tube halves and integrated in a seamless condition. An air chamber is defined in the first tube half, and a sealant chamber is filled with a sealant and is defined in the second tube half. When the tube is pierced, the sealant repairs a pierced hole to prevent the puncture. Further, the air chamber is separated from the sealant chamber, so that an air valve provided on the air chamber is not plugged with the sealant.

Abstract: The present invention refers to that position in which an assembling position of the shoulder bladder is connected with the expansion part thereof and stress is accumulated, and the expansion of the bladder and the assembling part are all wrapped with core-rubber composition to form a body.

Abstract: The present invention concerns an improvement in securing a tire stem assembly. Specifically, a rubber packing piece, washer and securing nut-containing rubber packing piece are employed in this assembly, which cause the tire stem to bind tightly to the hub when the inner tube is inflated. The merit is that air cannot escape quickly from the space between the stem and the hub when the inner tube of a tire is punctured by a sharp object, thereby allowing the motor-driven vehicle to continue to operate.

Abstract: A tire retreading tube for use with a tire retreading rim formed from a pair of axially-adjacent rim sections, one of said sections having a cutout for the reception of the valve stem extending from the tube body and being formed with threads adjacent the tube. The tube has an extension of generally cylindrical form through which the stem extends, so that the extension surrounds the portion of the stem adjacent the tube, and functions as a spacer element and is effective to limit movement of the stem and the tube relatively to the rim section. Suitably, the spacer element threadedly engages the stem adjacent the tube, has a body which essentially fills the cutout circumferentially, and has end flanges to overlie the adjacent faces of the rim section with which it is to be associated.

Abstract: Belt and tread transfer ring bladders and belt and tread drum expand bladders for use in fabrication of tires are provided with reinforcing layers (preferably of aramid fiber or fabric). The bladders are prepared by assembling on a cylindrical drum, first and second continuous, partially cured rubber belts with a layer of reinforcing material sandwiched there between. One edge of the continuous belt-sandwich is folded towards the outer edge, the latter edge is folded inwardly so as to overlap said first fold and the assembly is then cured advantageously using steam and pressure. The overlapped folds in the resulting bladder from the surface of the bladder which contacts the workpiece during use as either a transfer ring bladder or drum expand bladder. The bladder of the invention is found to possess a significantly extended working life as compared to bladders hitherto available.

Abstract: A tube assembly for use in a process of vulcanizing a pre-cured tread onto a tire casing is disclosed. The tube assembly includes an elastomeric tubular wall having an inner periphery with a protective non-woven fabric layer covering a major portion thereof. The fabric layer includes a plurality of polyester cords extending in parallel relation in a single ply elastomeric matrix. Longitudinal edges of the fabric are covered by thin strips of elastomer bonded to the fabric layer and the tube wall. Superimposed fabric reinforcing swatches are bonded to the fabric layer around the valve stem. The tube assembly is resistant to being damaged prematurely by the rim which supports the tire casing in the tread vulcanization process.

Abstract: Tires are typically inflated through an air conduit mounted on the tire carcass and extending through a hole in the metal rim on which the tire is mounted. Now and then relative slipping between the tire and rim has caused the air conduit to be sheared off, deflating the tire. The present invention overcomes this problem by moving the air conduit (26, 33, 37) completely away from the rim. The air conduit (26, 33, 37) extends from the air chamber (12) through the track wall (10) to the side wall (8) of the carcass (7) and terminates in an air valve receptacle (27) accessible at the side wall (8) of the carcass (7).

Abstract: An inner air-tube of a tire for bicycle, particular for racing cycle substantially composed of a thermoplastic urethane resin of a specific type. The urethane resin is comprised of a bifunctional polyol, a diisocyanate and a diol serving as a chain-propagating agent, the ratio by mole of the diisocyanate to a mixture of the bifunctional polyol and the diol being in the range of 1.05-1.10:1. The urethane resin of this type is readily after-crosslinked to improve its physical properties to a great extent.

The tacking members (120,125,120) are preheated to a tacking temperature so that when the frame (40) is clamped onto the carcass (15), and the elongate material or cables (32) are spread, the spread elongate material or cables (32) are tacked to the carcass.

Abstract: The thorough bonding required between the base or flange of a molded rubber sleeve for a valve, and a tire tube of rubber or the like, is realized by simulating the roughened effect normally produced through abrasion. Such effect is achieved by specially configuring the surface of the base in the molding process; that is to say, the surface normally resulting from abrasion is equivalently produced by forming the contacting surface of the critical mold portion (such as a plunger or the like) in a cross-hatched or knurled pattern, whereby a desired cross-hatched pattern is formed in the particular surface of the base.

Abstract: Process for open vulcanization of innertubes wherein the completed green tube with valve and valve stem installed is folded and arranged on a surface with rods from about 13 to about 25 mm in diameter inserted in the folded ends. Air amounting to from about 7.5% to about 12.5% of the nominal fully inflated volume of the tube is injected and the thus-arranged and partially-inflated tube is exposed to open air or open steam curing at a temperature in the range of from about 150.degree. to about 190.degree. C. The resulting tube has edges and end folds of increased radius of curvature minimizing subsequent fatigue or flex cracking in service.

Abstract: A method of bonding a valve stem assembly adapted to a rubber sheet which includes the steps of inserting the stem in a concave mold, surrounding one end of the stem with an uncured rubber ring, inserting a removable plug in the core of the stem, placing an imperforate rubber sheet over the plugged end of the stem, and applying heat and pressure to the assembly so as to mold the ring and sheet around the end of the stem. The plug is then pushed out of the core of the stem.
