Claims

[Scope of utility model registration request]

A saw cylinder that cuts the running paper into a predetermined length in cooperation with folding cylinders that are close to each other, and a saw cylinder that guides the running paper to the outer periphery of the lower half thereof, and the tip draws a hypocycloid curved trajectory to cut the running paper to the outer periphery. a folding cylinder which has a folding blade protruding from the folding cylinder, and which pushes the center portion of the cut running paper between a pair of folding rollers by the protruding tip of the folding blade; In a folding device for a rotary press, the folding device is equipped with a pair of folding rollers that hold the running paper pushed in by the tip of a folding blade and fold it in half, the folding roller facing backward in the rotational direction of the folding drum. A folding device for a rotary press, characterized in that a protrusion is provided on the side surface of a blade.
