Since the signatures were inevitably left with scars from the gripping, the signatures had to be made extra long to accommodate the gripping, resulting in wasted paper strips. Furthermore, there are also drawbacks such as the fact that increasing the printing speed is limited to the limit speed of the gripping claw device, and there has been a desire to improve this.

A gap is created between the trailing edge of the signature of the previous page and the leading edge of the signature of the next page by pinching and pulling it between timing rolls with increased circumferential speed, and a separator is inserted into this gap. Timing the separation plate (
It is configured so that when the separation plate is rotated and inserted, the signatures are sorted to the left when the separation claw of the separation plate is inserted, and to the bottom when the notch of the separation plate is inserted.

This is a half of the guide belt 52 hung on the belt pulley 45 of No. 0, and the hooks are passed so that they overlap each other and move along the edges of the guide belt 52. Then, a nip is formed between the guide belt 52 on the belt pulley 45 of the separator 40 and the guide belt 59 hooked on the small-diameter belt pulley 56, and the sorted signatures are pressed to ensure that they are transported downward. It is formed like this.

。Next, the operation of this example of the folding machine configured as described above will be explained. A paper strip printed by a rotary printing press (not shown) is folded vertically at the center of the width of the paper strip by a former 1 to form a paper strip 20.
The sheet is then cut into pages A and 8 using the cutting cylinder 2 to form signatures. This signature is inserted into a nip formed by a pair of guide belts 52 and 53, and then transported while being held between the belts 52 and 53, and the pair rotates at a circumferential speed that is 4 fl faster than the transport speed of the paper strip 20. The signature is pulled by the timing roll 35, and the trailing edge 55a of the signature 55 of the previous page and the leading edge 56 of the signature 56 of the next page are pulled.
An interval Q is created between a and a. When the separation pawl 41b of the separation plate 41 of the separator 40 is inserted into this interval Q by aligning the timing as shown in FIG. It is distributed to the left side and sent to the nip formed by the left side of the tip 68a of the guide plate 68, and then it is held between the guide belt 53 and the belt 61 hooked on the small diameter guide roller 57 of the guide device 60, and is sent to the impeller on the lower left side. Transferred to 17, 8
The page signatures 56 are arranged and discharged on the paper discharge table 19.

８上にＡ頁の折丁を整列して排出する。Next, when the signatures 55 are transferred as they pass through the notch 41a of the separation plate 41, the signatures 55 continue straight and are connected to the guide belt 52 of the belt pulley 45 of the separation plate 41 and the guide device 6.
The paper is transferred to the nip formed by the guide belt 59 on the small diameter belt pulley 56 of 0, and then transferred to the impeller 16 on the lower right side while being held between the guide belts 52 and 59, and then transferred to the discharge table 1.
8, the signatures of page A are arranged and discharged.

との摩擦抵抗を軽減させるようになっている。Since the small-diameter belt 56 of the guide device 60 slightly protrudes from the guide F268, the leading edge of the signature 55 that is conveyed while being held between the guide belts 52 and 59 is wrapped around the outer periphery of the small-diameter belt wheel 56. The guide plate 68 is actuated to contact and feed the guide belt 59.
It is designed to reduce frictional resistance.

駆動すると、Ａ頁。Next, as a modification of this example, the clutch 73 of the drive shaft 42 is released and fixed so that the notch 41a is in the nip without rotating the separation plate 41 of the separator 40, and the impeller 16 is fixed.
When driven by a switching gear mechanism 72 that doubles the rotational speed of page A.

に排出できる。It is also possible to eject the eight pages together onto the ejection table 18 without separating them. Similarly, if the separation claw 41b of the separation claw 41 of the separator 40 is fixed so as to face the nip, and the impeller 17 is driven at twice the speed by the switching gear mechanism 72, page A and The signatures on page 8 are the same.
can be discharged.

できる。Next, another embodiment of the present invention will be described based on FIGS. 5 and 6. This example is constructed by removing the guide plate 68 from the first example. That is, in the guide device 80, small diameter belt pulleys 56, 57 are rotatably held in a machine frame (not shown), and each narrow guide belt 59.
61 is multiplied. The small diameter belt pulley 56 is brought close to the nip point between the outer periphery of the separating plate 41 and the guide roller 51, and the signature 55 moves straight at the timing of the notch 41a of the separating plate 41 of the separator 40, and the signature When the leading edge 55a of 55 hits the guide heald 59 at two points, the guide belt 59 is moving in the clockwise direction of the arrow, so it is guided in the direction of movement, and the belt pulley 45 of the separator 40 and the small diameter belt pulley are guided. The signature 55 is sandwiched between the nip formed by the nip 56 and is surely transferred to the lower right side. On the other hand, in FIG. 6, the signature 56 is sorted to the left, and the leading edge 56a of the signature 56 is pushed by the guide belt 53 on the left guide roller 51 by the separating claw 41b of the separating plate 41 of the separator 40. It collides with the guide heald 61 hanging on the small diameter belt pulley 57, and since this guide belt 61 is being driven in the counterclockwise direction of the arrow,
The belt 61 and the guide belt 5 are guided in the direction of movement.
3, the signature 56 can be reliably transferred to the lower left side.
