    Abstract: Method and apparatus for highly efficiently forming a tire reinforcing layer on an outer peripheral surface of a rigid core (13), in which ribbon pieces (33) each comprised of parallel rubber-coated cords (17) are successively adhered to the outer peripheral surface of the core (13) in a circumferential direction thereof, with the side edges of the ribbon pieces in close contact with those of adjacent ribbon pieces. A plurality of cords (17) can be set by one adhering operation, thereby reducing the number of adhering operations in forming a tire reinforcing layer.

    Abstract: In the lamination of band-shaped uncured rubber materials to form a laminated rubber member having a given sectional shape by helically winding a band-shaped uncured rubber material extruded through an extruder (2) on a rotating support (1), two or more rubber compositions (A-C) exhibiting different moduli after curing are used as a rubber material fed to the extruder (2). A first rubber material (A) is extruded through the extruder (2) and helically wound on the support (1) to form a first rubber layer. Then the first rubber material (A) and a second rubber material (B) are fed continuously and simultaneously through the extruder (2) so as to stepwise or gradually increase the blending ratio of the second rubber material (B) to the first rubber material (A) while holding the same extrusion sectional shape and helically wound on the first rubber layer while overlapping with at least a part of the first rubber layer, to form a second rubber layer.

    Abstract: A tire building machine includes a single-stage type forming drum (13) for initially forming a carcass band (29) and subsequently forming a green tire (34), and a belt-tread drum (14) for forming a belt-tread band (31). These drums (13, 14) are carried by a horizontal coaxial shaft (12) on a base member (10) of the machine. An integrated transfer unit (16) is movable in a predetermined transfer direction on the base member (10). The transfer unit (16) includes a bead setter (17) for setting beads (23) onto an outer circumference of a carcass band (29) formed on the forming drum (13), and a transfer ring (18) for transferring a belt-tread band (31) formed on the belt-tread drum (14) and a green tire (34) formed on the forming drum (13). The bead setter (17) and the transfer ring (18) are connected to each other as an integrated unit, and driven by a single drive means in the transfer direction.
