That is, the ink of the left blanket cylinder 13c is transferred to the front surface of the web W, and the ink of the right blanket cylinder 13c is transferred to the back surface of the web W. Done.

  Next, the width register correcting device 21 will be described with reference to FIGS. 4 and 5. As shown in FIGS. 2 and 3, the width register correcting device 21 is provided between the stack b and the stack c. The width register correcting device 21 adjusts the register in the width direction of the web W based on the web data and the print data. That is, when the web W to be conveyed is printed by the stacks a and b of the printing unit U1, the web W is stretched in the width direction because the web W contains ink, moisture, and the like. In this state, when printing is performed on the web W by the stacks c and d of the printing unit U1, a printing shift occurs on the web W. For this reason, the misregistration (fan-out) is corrected by restoring the web W stretched in the width direction by the width register correcting device 21 to the width of the web W before printing. Here, the web data refers to the width of the web W (web size), the traveling speed of the web W, the tension of the web W, and the like, and the print data refers to the image line rate. In this case, the running speed and tension of the web W may be measured online using a sensor.

  As shown in FIGS. 4 and 5, the width register correcting device 21 is provided on one side (front side) of the traveling web W. The width register correcting device 21 is provided horizontally along the width direction of the web W and is provided in parallel with the web W, and eight wrinkle rollers 31 arranged on the support shaft 30 at predetermined intervals. And have.

  The eight wrinkle rollers 31 are rotatably supported with respect to the support shaft 30. The eight wrinkle rollers 31 are provided in a space between the water reciprocating roller 82 and the web W. The support shaft 30 is connected at one end (drive side) thereof to an attachment portion 47a of the moving block 46a by a connecting shaft 48a so as to be horizontally pivotable, and at the other end (operation side) thereof at the moving block. A mounting portion 47b of 46b is connected by a connecting shaft 48b so as to be horizontally rotatable. Screw shafts 49a and 49b are arranged on both sides of the running web W in the width direction along a direction perpendicular to the web W. The screw shafts 49a and 49b are driven by drive motors 50a and 50b. It can be rotated. The screw shafts 49a and 49b are screwed into the moving blocks 46a and 46b.

  Accordingly, when the screw shafts 49a and 49b are rotated in the forward rotation direction by the drive motors 50a and 50b, the moving blocks 46a and 46b move forward (moves upward in FIG. 4), and the eight wrinkle rollers 31 are provided via the support shaft 30 and the like. Can be moved in a direction approaching the web W. On the other hand, when the screw shafts 49a and 49b are rotated in the reverse rotation direction by the drive motors 50a and 50b, the moving blocks 46a and 46b are moved backward (moved downward in FIG. 4), and the eight wrinkle rollers 31 are provided via the support shaft 30 and the like. Can be moved away from the web W.

  In this way, the drive motors 50a and 50b, the screw shafts 49a and 49b, and the moving blocks 46a and 46b move the wrinkle roller 31 in the direction approaching the web W and press the wrinkle roller 31 against the web W. It functions as a mechanism 86.

  The width register correcting device 21 as described above moves the eight wrinkle rollers 31 in a direction approaching the web W and presses it from one surface of the traveling web W. Then, this web W becomes a wave shape by the part pressed by each wrinkle roller 31 projecting to the other surface side. Therefore, although the web W is extended in the width direction by the ink or dampening water supplied by printing, the length in the width direction is shortened by the wrinkle roller 31 and the length before the printing is reduced. The length can be corrected, that is, the fan-out can be corrected. As a result, the misregistration between the web W and the printed image can be adjusted.

  By the way, the wrinkle roller 31 of the width register correcting device 21 is disposed to face the water reciprocating roller 82 as shown in FIG.
