Abstract: A strip-like reinforcing laminate has at least two laminated strips each containing wave-like or zigzag reinforcing elements (1, 1 min ) covered with a particular polymer material, wherein each reinforcing element (1) in each of these strips has regions (2, 2 min ) crossing over at least two reinforcing elements (1 min ) included in the adjoining strip, and the reinforcing elements in all of these strips are aligned in the same direction. Further, such a reinforcing laminate is used as a reinforcement in various parts of a pneumatic tire.

Abstract: In accordance with the present invention, there are provided processes for preparing thermoplastic elastomer laminates, which comprise a step of obtaining a laminated sheet by placing a thermoplastic elastomer unexpanded sheet containing a polyolefin resin, and ethylene/.alpha.-olefin copolymer rubber and a foaming agent onto one face of a thermoplastic elastomer sheet containing a polyolefin resin and an ethylene/.alpha.-olefin copolymer rubber, and heat fusion bonding both sheets to each other, and a step of obtaining a thermoplastic elastomer laminate having a foamed layer by heating said laminated sheet to expand the thermoplastic elastomer unexpanded sheet layer thereof.

Abstract: A high inner pressure heavy duty pneumatic radial tire includes a carcass of a plurality of plies made of laminated organic fiber cord layers of which one ply is turned up about bead cores, and a belt made of a plurality of laminated cord reinforcing layers. The belt includes at least one set of packing structural reinforcing layers. Each of the packing structrure reinforcing layers includes cord reinforcing layers wider than a width of the arranged belt and having width edges folded inwardly to form folded layers and further cord reinforcing layers having widths as cut corresponding to inner widths of the folded layers and surrounded by the folded layers to form inner core reinforcing layers. The further core reinforcing layers are higher in circumferential rigidity than the first mentioned core reinforcing layers. Cords of the first mentioned cord reinforcing layers and the further core reinforcing layers are made of material substantially the same at least in modulus of elasticity.
