When the web running position is displaced due to the meandering of the printed web 2, the two web running position adjusting rollers 10 are moved in the arrow direction by the detection signal from the edge sensor 9, and the printed web 2 is moved in the web running direction. The printed web 2 is held in place by moving in a direction orthogonal to. The above is the control procedure when the printed web 2 deviates at a constant speed and within the control range. However, when the printed web 2 is accelerated or decelerated or when the printed web 2 deviates beyond the control range. The operator reads the amount of misalignment of the signatures ejected from the folding unit 6, corrects the zero point of the edge sensor 9 by manual input, and operates the web guide 8 to set the traveling position of the printed web 2 to an appropriate position. Correct to. Also, the zero point of the edge sensor 9 is corrected when the width of the printing paper is changed.

The conventional web meandering correction device shown in FIGS. 3 and 4 has the following problems. (1) Due to a sudden change in tension of the printed web 2 that occurs during acceleration / deceleration, the running position of the printed web 2 is displaced after the installation position of the web guide 8, and the printed web 2 on the triangular plate 7 is folded. Misalignment occurs. FIG. 5 shows an example of the case where a misalignment occurs. (2) In order to adjust this, the operator visually judges the deviation of the signature ejected from the folder, corrects the zero point of the edge sensor 9 by manual input, and adjusts the folding position to an appropriate position. Therefore, the printed web 2 is completely discarded until the adjustment work by the operator is completed, resulting in wasted paper.
Most of the waste paper is generated while the operator judges the misalignment of the signatures.
