特徴とする折機の重ね、非重ね切換え機構。 A saw cylinder having a saw blade that cuts the printed paper fed between the folding cylinder, a stacking cylinder to which the cut printed paper is delivered, and a biting claw that bites the printed paper fed from the folding cylinder. The gripping cylinder has an upper reduction cylinder and a lower reduction cylinder that are in contact with each other at the top and bottom of the gripping cylinder, the stacked cylinder has an odd number of needle devices, and a cam drive system for the needle device is provided with a fixed position separation clutch. In the case of stacking, the fixed position separation clutch of the cam for the stacking cylinder needle device is brought into contact, and the odd numbered printing paper (side A) is wound around the stacking cylinder, and after one revolution of the stacking cylinder, the folding cylinder and The printed paper is overlapped with the even-numbered printing paper (side B) and fed to the folding cylinder, and the printed paper is overlapped. If the printing paper is not overlapped, release the fixed position separation clutch of the cam for the overlapped cylinder needle device. By doing so, the cam is always stationary in a fixed position, and the printing paper is continuously fed to the folding cylinder in a non-overlapping state without being received by the stacking cylinder, and the folding cylinder has an even number of needle devices, and In addition to providing a needle device that is operated by a separate cam, it also has a device that can be switched by rotating one of the operating cams on the A side in the rotational direction, and in the case of overlapping, the operating cams on the A side are overlapped. The printing paper on the A side is always fed to the folding cylinder without being received by the folding cylinder, and the operating cam on the B side is
It is always set so that it is received by the folding cylinder, and the A-side printed paper after one rotation of the stacking cylinder and the B-side printed paper that is directly supplied to the folding machine are stacked and received, and in the case of non-overlapping, the A-side Set the operating cam on the side to the non-overlapping position, always wrap the printed paper on the A side around the folding cylinder without passing it to the stacking cylinder, set the operating cam on the side B side in the same position as in the case of stacking, and A stacking/non-overlap switching mechanism for a folding machine, characterized in that the printed paper is always wound around the folding cylinder without being passed to the stacking cylinder, so that the paper is continuously fed in a non-overlapping state.
