である。[0004] In recent years, the operation of such a rotary printing press has been increasing in speed, and there has been an adverse effect associated therewith. For example, on a rotary printing press, the signature of a signature called "dog ear" is broken (the corner of the signature flaps and breaks).
Also, a phenomenon such as paper breakage occurs. As shown in FIG. 6, the “dog ear” includes a front half 7 </ b> A of the signature 7, which is passed from the plunging cylinder 3 to the biting cylinder 10 (the part on the side stabbed with the needle device) from the needle of the needle device 4. Until it comes into close contact with the disengagement bite cylinder 10, it also occurs when moving while lifting (fluttering) from the plunging cylinder 3 due to centrifugal force.
While the front half 7A is still stuck in the needle, the rear half 7B of the signature 7 is released from the pressing of the plunging cylinder 3 and the biting cylinder 10, and then the traveling direction is suddenly changed and the biting part is changed. Is generated at the time of shifting to the biting cylinder 10 while moving up from the plunging cylinder 3 due to centrifugal force when moving to the biting cylinder 10 with the.

Not be. However, since the accuracy of the biting position changes depending on the degree of pressing of the plate brush 19, the pressing force of the brush is adjusted so that the plate brush is pressed according to the paper quality of the signature 7 and the gap between the two is always kept optimal. There is a problem that is difficult. In addition, brush 19A just before biting
If the brush 19A is strongly pressed against the plunging cylinder 3, there is also a problem that the brush 19A is greatly consumed. Therefore, in order to prevent the latter half 7B of the signature 7 from leading ahead of the ramming cylinder 3,
It is conceivable that an elastic member such as a sponge is embedded in the ramming cylinder 3 (or the biting cylinder), or a brush tape is adhered to the cylinder to nip a signature between the ramming cylinder and a counterpart cylinder. It is difficult to completely cope with changes in the number of pages and paper thickness of signatures, and even if sponge or brush tape is worn, it is almost ineffective.
