を経て機外に排出される。The operation of the folding machine will be described. The continuous paper W which has been printed and sent to the folding machine enters between the folding cylinder 24 and the holding cylinder 25, and the front edge of the continuous paper W is folded. It is carried along the outer circumference of the folding cylinder 24 by the needle device 10 of the cylinder 24, and is rotated to a predetermined angle and released from the needle device 10. The continuous paper W released from the staple device 10 is folded at the predetermined position of the continuous paper W by the blade of the folding blade device 17. At this time, the blade of the folding blade device 17 is inserted into the gap between the holding plate of the holding device 18 and the jaw 25j of the holding drum main body to fold the continuous paper W. Then, the folded continuous paper W has a predetermined size between the saw blade device 11 of the folding cylinder 24 and the saw blade receiver 12 of the gripping cylinder 25, that is, B3.
Cut to length. Thus, the signature S folded in two to the size of four pages of B4 size as shown in FIG.
3 is formed. The folded signature S3 is conveyed at a constant pitch by the conveyor belt 29, and the impeller 9
Is discharged outside the machine.

That is, it is cut into a B4 size length. The cut cutting paper S1 is conveyed along the outer periphery of the stacking cylinder 3 with its front edge held by the claw device 16a of the stacking cylinder 3, and is held in the claw device 16c of the transfer cylinder 35 every other copy. Will be replaced.
The cutting paper S1 that has not been transferred from the stacking cylinder 3 to the transfer cylinder 35 is conveyed while being overlapped with the subsequent cutting paper S1 that descends from the cutting section, and the claw device 16 of the transfer cylinder 35 is placed every other copy.
As a result, the two parts are held in a superposed state by a and are carried along the outer periphery of the transfer cylinder 35. Then, the cut paper S1 released from the claw device 16a at the predetermined position enters the impeller 9 in a state of being overlapped by two copies, and is discharged outside the machine via the discharge conveyor 14.

Conventional printing presses for commercial rotary presses have the following drawbacks when mainly printing flyers and the like. (A) The folding machine of the type having the folding cylinder 24 and the holding cylinder 25 can discharge the folded signature S3, but cannot output the sheet. When a sheet-like printed matter is formed by this folding machine, it is time-consuming and costly because the folded line of the signature S3 has to be cut by a separate cutting machine for the folded signature S3. In addition, the needle holes peculiar to the rotary press at the edges of these printed materials impair the appearance of the product. (B) A folding machine having a stacking cylinder 3 and a transfer cylinder 35 is capable of efficiently discharging a sheet-like printed matter without a needle hole without using a cutting machine as a post-processing device, but is a two-folded signature. Because of this, the use was limited.

When the printed matter of the page is to be discharged, first, the switching clutch of the drive system of the transfer cylinder 5 is set to the "sheet output" side. Then, the transfer cylinder 5 becomes a drive path that rotates together with the first cutting unit 1A and the stacking cylinder 3, and the second cutting unit 1B
And the drive path leading to the folding cylinder 4 is cut off. Next, the leading end of the continuous paper W1 sent to the folding machine is passed between the first saw cylinder 7A and the first receiving cylinder 8A, and paper threading as shown in FIG. 2A is performed. When the rotary press is started in this state, the continuous paper W1 printed and fed is a predetermined length between the saw blade device 11 of the saw cylinder 7A and the saw blade receiver 12 of the receiving cylinder 8A, that is, B
The sheet is cut to a length of 4 to form a cut sheet S1.

The front edge is held, and rotates along the outer periphery of the stacking cylinder 3. Since the transfer cylinder 5 rotates 1 / while the stacking cylinder 3 rotates 2, the claw device 16 of the stacking cylinder 3 rotates.
The cutting paper S1 that has been rotated along the outer circumference of the stacking cylinder 3 in addition to a is transferred to the claw device 16c of the transfer cylinder 5 only every other copy. For this reason, the cutting paper S1 that has not been replaced by the transfer drum 5 is pinched between the paper cutting belt S and the paper guide belt 13c along the outer periphery of the stacking drum 3, and is rotated from the first cutting device 1A. The preceding cutting paper S on the outer periphery of the stacking cylinder 3
