When a pressing force is applied to the roller 22, the sheet P can be elastically supported. As a result, even if the sheet to be folded is thick and strong, the spring member 21 is opened outward and deformed, so that the strength of the sheet can be elastically absorbed and the folding habit can be smoothly applied to the sheet. In addition, an unreasonable load is prevented from being applied to the drive shaft 10 and the driven shaft 11. After the pressing of the sheet is completed, the spring member 21 is restored to its original shape by its own elasticity, so that there is no possibility that the spring member 21 is deformed.

The mountain folding operation is performed by nipping and pressing the sheet P between the pushing blade B1 on the driving shaft 10 side and the pressing roller R2 on the driven shaft 11 side, and is substantially the same as the valley folding operation described above. , And a description thereof will be omitted.

ある。When the sheet P is pushed between the pressure rollers by the tip of the pushing blade, the spring member 21 is pressed.
With the elastic force of, the pressing roller presses the sheet P to form a folding habit at the perforation M. In such a configuration, since the pressure roller is rotated in accordance with the sheet P to be pushed in, the frictional resistance acting on the sheet P decreases, and the sheet P is pinched between the pressure rollers. This is advantageous in that the folding operation is facilitated. Further, since the pressing roller is supported by the spring member 21, even if the force of the sheet P acting on the pressing roller differs due to the difference in the thickness of the sheet P, the force can be absorbed. There is also an advantage that it can be widely used for papers having different thicknesses.

Are alternately performed, and the folds of valley folds and mountain folds are alternately formed and perforated at the perforations of the continuous paper, so that the continuous paper is smoothly placed between the pressure rollers by the tip of the blade. It is inserted to form a folding habit. Therefore, even for continuous paper having a wide width, the folding operation is performed without generating frictional resistance. Further, since the stiffness of the continuous paper can be more elastically absorbed, it is possible to form a folding habit more smoothly on continuous papers having different thicknesses.
