Consists of an azillomi machine blade 43 provided on the upper surface side of the signature 37 and a sewing machine blade receiving roller 44 provided on the outer periphery with a receiving groove 49 on the lower surface side of the signature 37 with which the cutting edge of the ajiromicine blade 43 engages. There is.

狂いやすい。As described above, in the case of the prior art, when the signatures 37 sent out from the occlusal body 36 at a constant interval enter the space between the azimuth sewing machine blade 43 and the sewing machine blade receiving roller 44, they are fulcrum points. Through a lever 46 that rotates about a shaft 45, an ajiromicine blade 43 compresses the spring 48 by the thickness of the signature 37 and moves upward, and when the signature 37 passes through, the signature 37 intermittently moves. Every time it passes, the vertical movement is repeated. Therefore, in the case of a signature 37 having a large thickness, the up-and-down movement of the ajiromomishin blade 43 becomes large and jumps up, and the blade edge of the ajiromomishin blade 43 is greatly separated from the surface of the sewing machine blade receiving roller 44, and from the receiving groove 49 as shown in FIG. It comes off and a gap S is formed between the cutting edge and the roller surface. Therefore, when the ajiromicine blade 43 is again engaged with the groove 49, the blade edge of the ajiromicine blade 43 does not normally enter the groove 49 of the ajiromicine blade roller 44, and as shown in FIG. It may come into contact with the outer peripheral surface and cause defects. In addition, the signature 37 conveyed to the asilomicin insertion device 42 has upper and lower belts 38, 3
It's just sandwiched in 9 so it's a signature 3
The position of 7 easily shifts to the left and right with respect to the running direction, and in addition,
Since the upper and lower belts 38 and 39 are double-moved, the signature 37 is not fed into the azilomicin machine inserting device 42 in a normal state at a right angle to the cutting edge of the azimuthic sewing machine blade 43, and the position of perforations is apt to shift.

という問題があった。[0009] In general, perforation is not formed in a signature 37 that is passed by a flexible belt at a high speed while the signature is not in a tensioned state, and since the signature is flexible, the precision is poor and the sharpness is not good. In the case of thin paper, when the perforations are inserted into the signature 37, the stiffness of the signature 37 is weak, and the perforation roller 44 is received by the aziro perforation blade 43 before the perforations are processed.
As a result of the signature 37 being pushed into the groove 49, the sharpness becomes poor and the position of the perforation also shifts. Also, in the case of a cardboard signature 37, since the folded upper half of the signature is lifted up, the perforation is bent from the position on the opposite side of the bite fold of the signature 37 to about 1/3 from the butt side to the butt side. Are processed (see FIG. 12). As described above, there is a problem that various troubles occur.

Next, this operation will be explained. The web 11 is sent to the aziromatic machine inserting device 12 by the pulling roll 10, and the aziromatic perforation 25 is processed in the traveling direction of the web 11 as shown in FIG. Subsequently, it is introduced between the cutting cylinder 33 and the cutting receiving cylinder 34, and cut into a signature 23 as shown in FIG. The signature 23 is folded into a signature 36 as shown in FIG. 4C at the folding line position 22 by the bite-folding device in the next step. At this time, since the aziromatic perforation 25 is symmetrically processed at the folding line position 22, the upper piece 37 and the lower piece 38 which are bite-folded respectively have the azilomatic perforation 25 exactly at the same position, that is, from the top. The signature 36 is formed by removing the perforations 25 from the bottom, so that the glue can permeate well from the top to the bottom during the aziro binding.

供できるという効果がある。As described above, according to the present invention,
Before the web is cut into signatures, the continuous web is tensioned while tension is applied to the web, so the perforations are smooth and the edge of the ajiro machine is sharp, making it suitable for thick paper. Since the perforations can be accurately processed without bending, there is an effect that it is possible to provide a sewing machine for agile binding that improves the efficiency of machine operation and prevents the occurrence of defective signatures.
