る。<Operation> Since the peripheral velocity V 2 of the second roller is faster than the frequency V 1 of the first roller, the sheet-shaped rubber has a frequency after passing through the first roller and finishing passing through the second roller. Difference (V 2 −
V 1 ) is pulled and stretched. When the push-cutting blade planted on the outer peripheral surface of the second roller bites in that state, the rubber is easily cut together with the restoring force of the rubber. The cut rubber chip returns to its natural state due to the restoring force of the rubber itself.
