Then, the running paper 10 that has passed through the printing unit 14 is attached to the first tension detector 24, passes through the idle roller 23, is supplied to the intermediate drag glow 215, and is slit into, for example, half width. Next, the running paper 10 is connected to a compensator 16 in which one web 101 is a straight portion.
The other web 102 passes through the turner 1 through the guide roller 25 to which the second tension detector 27 is attached.
7 and part of the turnpa through convencator 1Bk to the 3rd
The electrodeposited tension detectors 28 are supplied to the triangular plate drag rollers 19 via the idle rollers 26, respectively. Here, the webs 101 and 102 of the running paper 10 are joined again at the triangular plate dragrow 219, and the triangular plate 7
? '% After being fed through the nipping roller 21 to a folding machine 2211C and cut to a specified size, it is discharged outside the machine as a product. In this case, the cutting register in the folding machine 22 is controlled by the first. Each tension TI of the running paper 10 is measured by the second and third tension detectors 24°27.28.

The number of patterns staying in the running system between the running paper 10 and the running paper 10 is kept constant, and the number of drawings staying in the running paper 10 can be detected based on the length of the stroke and the elongation rate of the running paper 10. Therefore, in the rotary printing press, since the running paper 10 can be regarded as a roughly elastic body, the elongation rate can be detected by monitoring its tension, and the compensators 16 and 18 are adjusted according to the elongation rate. The cutting register is controlled to be constant by changing the length of the four sheets. It is something.
