The running paper (2) is sent to the printing unit (5) via all the rollers (3) and dancer rollers (4), where it is printed, and which has also passed through the printing unit (5). The web is slit in the longitudinal direction and goes to the triangular plate dog Q1 via the convencator (8) in the straight part, and the triangular plate drag (via the turn bar (1z) and the con insator (1: lt-) in the turn bar αa part. 11
It is divided into the web heading to
The webs of running paper (2) that have passed through 8) and a join again at the triangular plate dog a and reach the triangular plate (IQ).
After that, it is fed through the nipping roller ae and the folding machine αη, cut into specified dimensions, folded, and then discharged outside the machine as a product. The amount of deviation in the cutting register is visually determined, and if there is any deviation, the positions of each convencator (8) and (1st floor) are adjusted to match the amount of deviation to control the cutting register.

の断裁見当のズレ量は無視してよい。Also, between the reel stand (1) and the printing unit (5), a dancer roller (4) is used to apply tension to the running paper (2).
, the tension T1 of the running paper (2) supplied to the printing unit (5) is always kept at a constant value. In addition, the cutting register control of the running paper (2) is performed by controlling the tension T2, I3 of the running paper (2) at each part of the rotary printing press, for example, the guide roller (6), the guide roller (9), the guide roller (14), and the dancer roller (4). I4. and T1 are detected, and each compensator (8) and ( 13).Since the length of the running paper (2) between the triangular plate dog a and the folding machine α is short, the amount of misalignment in the cutting register during this time can be ignored. good.

Next, the cutting register control will be specifically explained. The cutting register control is to keep the number of patterns (total number of pages) of each web between the printing unit (5) and the folding machine (17) constant. It depends on the span length and the elongation rate of the running paper (2).

By changing the span length, it is possible to keep the cutting register constant. For example, when the running paper (web) (2) is on the straight path line, the total number of pages of the running paper (web) (2) between the printing unit (5) and the triangular plate P/F can be expressed by the following formula: become that way.
