Abstract: A tire loader for supplying a green tire into a vulcanizing press, comprising a plurality guide tracks extending radially outwardly, a plurality of grippers movably mounted on the guide tracks, respectively, for gripping a bead of the green tire in contact therewith, a plurality of fluid cylinders having rods connected respectively to the grippers and actuatable for moving the grippers along the guide tracks, and a stop for limiting the radially outward movement of the grippers along the guide tracks.

Abstract: An improved tire vulcanizing press of the type including an upper frame, a lower frame and side frames by way of which said upper frame and said lower frame are integrally connected to one another, wherein a lower die half is fixedly mounted on the lower frame and an upper die half is fixedly secured to a raising and lowering table adapted to be raised up or lowered by means of a raising and lowering means fixedly attached to the upper frame in such a manner that the upper die half is displaced away from or toward the lower die half is disclosed, wherein the improvement consists in that a working cylinder, a spacer and a distance plate are arranged between the upper frame and the upper die half, said distance plate being adapted to move from the operative position in the vulcanizing press to the inoperative one located outward of the latter and vice versa, whereby vulcanizing operation is safely carried out with the minimized die opening in the event of malfunction caused with respect to the working cylinder.

Abstract: An improved forming apparatus for a breaker layer to be used in a radial tire is described herein. The apparatus essentially comprises a drum device (D), a press contact device (A), first and second breaker material folding-wrapping devices (B) and (C), means for rotating said drum device (D), and means for moving said respective devices (A), (B) and (C) in the axial direction relative to said drum device (D) and for fixing them at predetermined positions. The drum device (D) includes a plurality of segments which have a width of their outer circumferential surfaces approximately equal to the width of the breaker layer to be formed, which can form a substantially cylindrical press contact surface with their outer circumferential surfaces, and which can expand and contract the diameter of said cylindrical contact surface.

Abstract: A method for press-bonding molding of breaker layers for radial tires by pressing the breaker plys on a molding drum to form a cylindrical breaker layer. The method is characterized in that at least during the press-bonding of the breaker plys, the press-bonding face which makes no parallel relative movement with respect to the face of the breaker ply to be press-bonded.
