Claims

[Scope of utility model registration request]

It has 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 folding blade that guides the running paper to the outer periphery of the lower half thereof,
This folding blade cuts the running paper into 1 piece.
A folding cylinder that is pushed between a pair of folding rollers, and a pair of folding rollers that are disposed close to each other below the folding cylinder and that grip the running paper pushed by the folding blade and fold it in half. In the folding device for a rotary press, the folding blade is composed of a plurality of folding blades arranged at a predetermined interval in the axial direction of the folding drum, and the outer peripheral surface of the folding roller facing the folding blades has a small diameter. When the folding blade pushes the cut running paper between the folding rollers, the tip of the folding blade reaches near the nip portion along the small diameter portion of the folding roller. A folding device for a rotary press.
