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.

Roll molding device

A first roll () and a second roll () of a roll forming device are provided with a plurality of stacked cutting blades () and retainers (). The retainers () pass through the stacked cutting blades () and receive a first rotating shaft () and a second rotating shaft (). Projections () are formed on end portions of the retainers (). When the cutting blades () are stacked, the projections () control positioning operation of the cutting blades (). With this constitution, when the cutting blades () are joined in a stacked state to the retainers (), the cutting blades () in the stacking direction is controlled with the retainers ().
