Abstract: A pneumatic tire has a tread portion, a pair of axially spaced bead areas and a pair of sidewalls. A body ply carcass extends axially between the bead areas and contains three body ply layers which turn-up about the bead areas from inside to outside. Two of the body ply layers are of equal axial lengths with the third body ply layer being considerably less or greater than the other two layers. The highest turn-up end of at least one of the body ply layers has a height of between 42% and 55% of the tire section height.

Abstract: A pneumatic radial tire includes a belt comprised of at least two rubberized steel wire element layers, in which the belt comprises an outermost slant element layer containing the steel wire elements obliquely arranged with respect to an equatorial plane of the tire and at least one circumferential element layer located inward from the outermost slant element layer in a radial direction of the tire and containing the steel wire elements arranged substantially in parallel to the equatorial plane, and a coating rubber for the steel wire element in the outermost slant element layer has a given modulus of elasticity at compression, and a sum of sectional area of the steel wire elements in the circumferential element layer per unit length is larger than a sum of sectional area of the steel wire elements in the outermost slant element layer per the same unit length.

Abstract: Cellulose extrudates can be made from an optically anisotropic solution containing 94-100 wt % of: cellulose; phosphoric acid and/or its anhydrides; and water by extruding the solution, coagulating the formed extrudates, and then aftertreating those extrudates so that they have a degree of acidity which at least equals 7. Fibers obtained by such a processs possess particularly good thermal stability and are suitable for use as a reinforcing material.

Abstract: A controlled bladder wrap tool system and method are disclosed for edge wrapping a substrate in a tool with consistent process control. An expandable bladder or bladder diaphragm is mounted in the tool adjacent a cavity where it expands when inflated to fill the cavity and to bend, fold or wrap an overhanging portion of pliable material onto a substrate which are mounted in the tool.
