A chuck (4) grasping the front edge of a tire component material (S) which is supplied from a material feeder (3) generates a motional locus through an initial ascending motion and through a forward motion toward the former and through a subsequent descending motion to the former to lay the front edge onto the carcass (T). A pressing mechanism (6) operates to press the introduced material (S) on the carcass (T), and concurrently the former (2) rotates by a predetermined rotation angle to adhere the tire component material (S) onto the carcass (T). Thereafter a cutter assembly (5) operates to cut the tire component material (S) in a length corresponding to the sum of a required length for joint and a full circumferential length of the carcass. The former (2) rotates again to adhere the tire component material (S) onto the full circumference of the carcass (T), and the front edge and a last edge of the tire component material are jointed by the pressing mechanism (6) so that the adhesion is completed. The method and the apparatus for adhering tire component material when compared with the manual work of the workers, enables a sharp improvement of the productivity to be made due to automation and no longer requires a high degree of worker's skill. Additionally, the quality of the products becomes stable and high, and the tire uniformity is improved.
An apparatus for adhering tire component material, employing a chuck comprising a support plate held by a frame freely movable back and forth relative to a drum-shaped former, a press plate for grasping the tire component material in cooperation with the support plate, a lever for moving the support plate during the back and forth movement, the lever moving the support plate up and down along a predetermined path with a shaft of the support plate being slidingly in contact with a contour of the lever, and driving means for moving the press plate up and down relative to the support plate, said chuck grasping a front edge of the tire component material fed from a material feeder to lay the tire component material onto a carcass on a tire former from above relative to the former surface.
