ABSTRACT:
A parallel folding apparatus of a folding machine comprises a first cylinder in contact with a second cylinder. A guide plate guides a signature transported on the lower circumferential surface of the second cylinder after being double-folded by grippers of the second cylinder in cooperation with knives of the first cylinder. The guide plate comprises a stationary guide located downstream, in the rotating direction, of the point of contact between the first cylinder and the second cylinder and disposed continuously along the circumferential surfaces of the first cylinder and the second cylinder, and a moving guide movable in accordance with the operating speed of the folding machine between a position, closer to the circumferential surface of the first cylinder than the stationary guide, and a position, more remote from the circumferential surface of the first cylinder than the stationary guide.
