<p>A synchronous control method and apparatus are disclosed for a web rotary printing press which includes a first printing press (A), a second printing press (B), a drive motor (115) for driving the secondprintingpress, and a folder (10) provided in the first printing press, and enables a web (W1) printed by the first printing press and a web (W2) printed by the second printing press to be superposed and folded by the folder. The synchronous control apparatus comprises a pattern phase deviation detecting sensor (17) provided halfway through a transport path, on which the web (W2) printed by the second printing press takes until the web is superposed on the web (W1) printed by the first printing press, and adapted to measure the position of a pattern printed by the second printing press, and a pattern phase deviation computing device (18) and a central control device (12) for controlling the rotation phase of the drive motor based on the position of the pattern printed by the second printing press, the position having been measured by the sensor.</p> |
