Abstract: A green tire feed system provided between the forming process and the vulcanizing process in a tire manufacturing installation. This green tire feed system comprises pallets, each adapted to be charged with green tires, pallet loading tables disposed respectively in front of the respective vulcanizing machines installed in a row, shelves disposed in opposition to the pallet loading tables, a stacker crane adapted to travel through a passageway formed between a row of the pallet loading tables and a row of the shelves, a station for receiving pallets sent from forming machines and from the pallet loading tables, and control devices for controlling the stacker crane. The stacker crane is controlled by the control means to transport a pallet charged with green tires form the station to the shelves and from the shelves to the pallet loading table, and to transport an empty pallet from the pallet loading table to the station.

Abstract: In order to grind the inner surface of a vehicle tire together with a mold releasing agent for amending an unbalanced portion on the tire and scars on the inner surface of the tire, a grinding apparatus is operated in an automated fashion and comprises a frame structure, a supporting member mounted on the frame structure, a swing member pivotally mounted on the forward end portion of the supporting member, a grinder wheel rotatably mounted on the lower end portion of the swing member, a swing member swinging mechanism mounted on the supporting member for swinging the swing member about its own axis, a grinder wheel rotating mechanism mounted on the supporting member and the swing member for rotating the grinder wheel, a tire rotating mechanism mounted on the frame structure opposing to the grinder wheel for holding and rotating the vehicle tire at a predetermined peripheral speed, a grinder wheel moving mechanism mounted on the frame structure for relatively moving the supporting member and the tire rotating
