    摘要: At a cut end portion of a belt-like member is formed a jointing surface, which is inclined at a small angle with respect to the surface of the belt-like member, simultaneously with cutting. A belt-like member (32) on a conveyor belt (6) is pinched under a pressure by an upper die (29) and a lower die (33) heated respectively by heaters (30) and (34), thereby it is subjected to plastic deformation and cut, and also jointing inclined surfaces are formed at the cut end portions. A die holding member (24) for holding the upper die is reciprocated in the vertical direction, by an action of a rotary shaft (11) having an eccentric cam (18). A separating member (38) which is moved vertically by another cam (40) operates as delayed with respect to the movement of the upper die, and when the upper die leaves the belt-like member, it presses the belt-like member to insure separation of the die.

    摘要: A system of manufacturing a high-lug tire, wherein a portion of the tread of an unvulcanized tire is cut off to form quasi pattern grooves in substantially complementary relation to the shaping surface of a vulcanizing mold. Thereafter the unvulcanized tire is vulcanized in vulcanizing mold with the quasi pattern grooves matching the shaping surface of the vulcanizing mold. This reduces any flow of rubber during vulcanization of the tire.
