PROBLEM TO BE SOLVED: To provide a method and a device for supplying a belt-shaped material which can improve the tire uniformity by suppressing fluctuations in the peripheral elongation amount in the drum transfer of the belt-shaped material to uniformalize it, when the belt-shaped material on a material supply conveyor is wound around a transfer drum, in a transferring servicer of tire molding. SOLUTION: In molding a tire, when the belt-shaped material placed on the material supply conveyor is wound around the transfer drum, while being expanded, a pushing plate is moved to a pushing position by swinging a swing arm on a rotation support, to hold the end part of the belt-shaped material between the pushing plate and the surface of the lifted material supply conveyor until 80% to 85% of the winding up amount of the belt-shaped material is reached. After that, the pushing plate is retreated to a retreat position to release the end part of the belt-shaped material. COPYRIGHT: (C)2004,JPO
