    Abstract: A tire building system, which does not require prolonging tact time for tire building, specific occupying space for endless circulative traveling of a building carriage, and increasing noises and vibrations, and which is free from possibility of premature deterioration of carriage positioning accuracy. The system includes workstations configured to mount applicable tire components onto a building drum, respectively; a building carriage configured to support the building drum to thereby move the building drum among the respective workstations; and carriage guiding means for guiding a movement of the building carriage on a predetermined path. The carriage guiding means includes two inner and outer endless rails, and wheels provided on the building carriage, the wheels each being configured to roll on opposite side surfaces of associated one of the endless rails to thereby restrict a carriage position in a direction orthogonal to an extending direction of the endless rails. The endless rails are each configured with a straight portion and an arcuate portion which are smoothly continued to each other, and the arcuate portion has a rail width W narrower than a rail width of the straight portion.

    Abstract: A rubber material for a tire-constitutional member is laid on a rotating support (1) with high efficiency and high accuracy by arranging a pair of rollers (11,12) rotating in opposite directions in the vicinity of a radially outer surface portion of the support and utilizing a gap (DR) defined between the rollers as a roller die. Specifically apparatus (10) for laying rubber materials for tire-constitutional members around a rotating support (1) comprises a volumetric extruder (25) for feeding an uncured rubber material onto the rotating support, a pair of rollers (11,12) located near to an outlet port of the volumetric extruder and near to a radially outer portion of the rotating support and driven in opposite directions to each other, and a gap (DR) defined between the pair of the rollers and serving as a die for the rubber material to be laid.

    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 single-stage tire forming system includes a belt drum (1), a band drum (2) and a shaping drum (3), which are linearly arranged in order on a base (9) from its one end to the other. A first drive unit (5) is arranged at one end of the base (9) and coaxially supports and drives the belt drum (1) and the band drum (2). A second drive unit (8) is arranged at the other end of the base (9) and supports and drives the shaping drum (3). A transfer unit (10) is provided and transfers a belt-tread band (25) from the belt drum (1) and a carcass band (26) from the band drum (2) to the shaping drum (3) where they are assembled with each other to form a green tire (35).
