Since it follows the front rollers 46 and moves upward without sagging, it does not come off from each roller, and the upper and lower conveyor belts 53, 56, 61 are largely opened, so Easy to remove. After clearing the paper jam, rotate the handle 40 180 ° counterclockwise to pull the knob 40b and the bracket 34.
Since the pin holes of the above are engaged by the elastic force of the compression coil spring 40c, the conveyor belts 53 and 56 come into contact with each other with the contact pressure as before, and the signature can be captured and conveyed smoothly.

In the present embodiment, the transfer cylinder 27 is exemplified as the final folding cylinder, but the folding cylinder can also be applied to a folding machine having the gripping cylinder 2 as the final cylinder as shown in FIG.

[Effect of device]

As is clear from the above description, according to the present invention,
The signature released from being held by the final origami cylinder is clamped between the upper conveyor belt and the lower conveyor belt on the front side that contacts the final origami cylinder, and the signature is released from the presser to the release position by the chopper device. Instead, it is clamped and released by a series of conveyor belts, so paper jams due to interruption of conveyance can be minimized, the amount of waste paper is reduced, productivity is improved, and stable and reliable conveyance is achieved. Therefore, the folding accuracy of the chopper device is improved. In addition, since the front lower conveyor belt is attached to the peripheral surface of the final origami cylinder, there is no need for a guide that guides the signature between the upper and lower conveyor belts, and the signature is not damaged or jammed. It does not occur and the quality of printed matter is improved. Furthermore, if a paper jam occurs, by separating the upper conveyor belt from the front and rear lower conveyor belts,
Since the space between the upper and lower conveyor belts is largely opened, all jammed paper can be easily removed, and in order to perform the operation, a lever that swings the arm that pivots the front roller is provided. Since the paper jam can be easily removed by an easy operation and the conveyor belt does not come loose from the rollers, the work efficiency is improved. Also, by making it possible to adjust the pivot angle of the arm that pivotally supports the front roller, it is possible to adjust the contact pressure at the entrance between the upper and lower conveyor belts, and release it from the grip of the final origami cylinder. The folded signatures are reliably captured by the upper and lower transport belts, and are smoothly transported.
