Abstract
An object is to provide a tire reinforcing layer forming device which can form, by a single device, plural reinforcing layers whose cord directions intersect one another. A reinforcing material pieceA, which is distributed to an upper conveying pathU, is affixed from a left end side of a drumtoward a right side, while the drumis rotated in a direction of arrow CW. In this way, the reinforcing material pieceA, which is affixed to an outer peripheral surface of the drum, falls to the right, i.e., rises to the left. Thereafter, similarly, the reinforcing material piecesA are successively affixed without gaps, and a first reinforcing layer is formed. Next, the reinforcing material pieceA, which is distributed to a lower conveying pathD, is affixed from the left end side of the drumtoward the right side, while the drumis rotated in an opposite direction. In this way, the reinforcing material pieceA, which is affixed to an outer peripheral surface of the first reinforcing layer, rises to the right. Thereafter, similarly, the reinforcing material piecesA are successively affixed without gaps, and a second reinforcing layer is formed.
