Abstract

In the present invention, when synchronization is lost due to backlash, and deviation between the rotational phases of a first processing roll and a second processing roll occurs, deviation between the rotational phases of dummy rotating bodies also occurs, and dummy blade parts of the dummy rotating bodies interfere with each other before blade parts of cutting blades of the first processing roll and the second processing roll () interfere with each other. Thus, interference between the blade parts is prevented.
