Claims

[Claims for Utility Model Registration] A pair of wheels arranged close to each other below the folding cylinder, which grip and fold the running paper into two by rotating synchronously, which is pushed in by the tip of the folding blade. In a folding roller for a folding device of a turning machine, at least one of the pair of folding rollers has a roller body and an axis at one end of the roller body, which is formed to have the same diameter as the roller body and is on the side of the roller of the traveling paper passing through. The roller part is fitted coaxially with the roller body and the phase in the circumferential direction can be adjusted with respect to the roller body. When the rear end passes,
A folding roller for a folding device of a rotary press, characterized in that a recessed portion that does not hold the rear end portion is partially formed in the circumferential direction.
