2) With the sheaf [2] held in place by the gripper [1] the paper positioning plate [3] lowers, moving the sheaf in the direction of the arrow. Thus, the stitching position

[4] and the folding position [5] are aligned.

3) After the paper folding roller begins to rotate in the direction of the arrow, the paper guide plate moves in the direction of the arrow. This starts the paper folding

operation.

Then, the paper stay plate is returned to its original position and stops.
