Abstract:
1. A tire reinforcing layer forming device forming a tire reinforcing layer on an outer peripheral surface of a drum, the tire reinforcing layer forming device comprising: a drum able to rotate in both forward and reverse directions; conveying means for conveying, toward the drum, a strip-shaped reinforcing material in which a plurality of cords, which are aligned parallel to one another, are rubber coated; cutting means for cutting the reinforcing material obliquely with respect to a transverse direction of the reinforcing material; a first conveying path provided at a reinforcing material conveying direction downstream side of the cutting means, and guiding the reinforcing material toward the drum; a second conveying path provided at the reinforcing material conveying direction downstream side of the cutting means, and guiding the reinforcing material toward the drum; distributing means for distributing the reinforcing material, which has been cut, to one of the first conveying path and the second conveying path; and axial direction moving means moving at least one of either the first conveying path or the second conveying path along an axial direction of the drum, while discharging the reinforcing material from the one of either the first conveying path or the second conveying path to the rotating drum; wherein the distributing means distribute the reinforcing material to the first conveying path and the second conveying path at an initial orientation, the first conveying path is twisted so that a reinforcing material exit of the conveying path is inclined with respect to the initial orientation, and the second conveying path is twisted so that a reinforcing material exit of the first conveying path is inclined with respect to the initial orientation, and the second conveying path is twisted so that a reinforcing material exit of the second conveying path is inclined with respect to the initial orientation in a direction opposite the reinforcing material exit of the first conveying path.
