    Abstract: A new and improved apparatus and method for producing torsion cords comprising the steps of: (1) casting a torsion cord of a rubber composition, the mold having a high pressure resistant cylindrical wall and opposite closed ends, (2) efficiently curing the rubber composition at a moderate temperature and high pressure for an extended period of time in the mold, (3) reducing the pressure in the mold, and (4) removing the molded torsion cord from the mold. An improved torsion cord manufactured by the method of the invention is also provided having closely controlled dimensions and improved physical properties with fewer process control procedures.

    Abstract: A tire for a two-wheeled vehicle comprising a ground contacting tread having at least one tread groove formed therein and extending axially from the tread center to the tread edge, wherein in a first region of the tire tread, which is the central tread region and is the region of contact between the tire and the ground when the motorcycle is in the condition of moving in a straight line, the alignment of the tread groove is substantially circumferential, and in a second region of the tire tread, which is at the axial edge of the tread and is the region of contact when the motorcycle is in the condition of turning under maximum cornering, the alignment of the tread grooves is substantially transverse, and in a third region, which is the tread region between the first central region and the second axial region and which is the ground contacting region when the motorcycle is turning at less than the maximum cornering condition, the groove alignment changes progressively axially outwardly from substantially circumferential to substantially transverse so that in the first, second and third axial regions of the tire tread the tread grooves are substantially aligned with the resultant forces acting on the tire tread surface in the contact region between the tread and with the ground.
