Abstract: An aircraft tire with two aquachannels (14) provides a wide band area (17) in the central portion of the tread for improved wear properties. The aquachannels each comprise 4.5% to 7% of the tread width based on the design tread width of the tire.
Abstract: Rubber composites, for example pneumatic tipes, can be made using seamless, tubular reinforcement (14). By pulling socks of seamless tubular reinforcement over, for example, a tire building drum (10), spliceless carcass reinforcement (18) and spliceless belts (64) can be incorporated into tires. Methods of treating the spliceless tubular material, by drawing and by adhesive coating, enhance its strength and adhesion to rubber.
Abstract: A tire (10) having a continuous folded belt construction (24) is shown to be more durable than conventional tire made using conventional steel reinforced cut belts. The folded belt construction of the invention is made by folding a reinforced (22) strip upon itself, wherein the folding is always in the same direction. The continuous folded belt construction may include an elastomeric core (23) that provides adhesion between the folded layers, and reduces kinking at the folded edges. Also, a splice (28) is used wherein substantial overlap is provided between two ends of the folded belt construction, and is made by cutting a first end (32) of the belt construction to accommodate a second end 44 of the belt construction (24) without modifying the second end 44 of the belt construction, thereby using a minimum amount of labor.
Abstract: A pneumatic tire for heavy duty use comprises at least one radial carcass ply, a tread portion disposed radially outwardly of the crown region of the carcass plies and a crown reinforcing structure interposed between the tread portion and the crown region of the carcass plies. The crown reinforcing structure includes a belt assembly having at least a first, radially innermost and a second, radially outermost belt ply. The cords reinforcing the belt plies are preferably made of PET or PEN and have a linear density comprised between 2000 and 16000 Denier, a twist comprised between 2 and 7 TPI and a twist multiplier comprised between 3 and 5.
Abstract: A method and apparatus for bundling layered material comprises an anvil for receiving multiple units of bundled material, and a plurality of blades for compressing a tying material onto the bundled material. An apparatus of the invention is illustrated for use in a specific method of simultaneously stapling the end wire of a plurality of tire beads.
Abstract: A method for detecting leakage of an expansion vessel 14 that, in an inflated form, occupies or has occupied at least a portion of a cavity 24 of an elastomeric article. The method includes the step of adding a tracer gas to a pressurized fluid. The method is characterized by the step of examining the atmosphere within the cavity of the elastomeric article, not within the expansion vessel, for evidence indicating that a portion of the tracer gas has escaped from the expansion vessel.
