Abstract
Provided are a rubber material supplying method and a rubber material supplying device, whereby a rubber material can be smoothly supplied to a rubber inlet even when the width of the rubber material is greater than the width of the rubber inlet. The rubber material supplying method includes a separation step S1, a processing step S2, and an input step S3. In the separation step S1, a plurality of different cutouts 30 are formed in a leading end section GF of a rubber material G, and the leading end section GF is separated into three or more strip shape sections 31. In the processing step S2, second strip shape sections B, and not first strip shape sections 31A, among the plurality of strip sections 31 are each cut out or folded. In the input step S3, the leading end section GF is input to the rubber inlet 3A from the first strip shape sections 31A.
