Abstract

A synchronous control method and apparatus are disclosed for a web rotary printing press which comprises a first printing press, a second printing press, a drive motor for driving the second printing press, and a folder provided in the first printing press, and enables a web printed by the first printing press and a web 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 provided halfway through a transport path, on which the web printed by the second printing press is transferred so that the web is superposed on a web 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 and a central control device 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.

Description

technical field [0001] The invention relates to a synchronous control method and device for a web rotary printing machine. Background technique [0002] Conventionally, in Patent Document 1 (JP-A-6-328672) and Patent Document 2 (JP-A-2005-304109), it is disclosed that a plurality of offset rotary printing machines operate synchronously, and that each offset rotary printing machine Printed roll paper is cut / folded with a folding machine in a stacked state, such as duplex (DUPLEX) or triplex (TRIPLEX) operation technology. [0003] In these technical solutions, when long-run printing is performed, due to the difference in the length of the web conveying path between the synchronously operated master machine and the slave machine and the elongation of the web, there is a gap between the printed parts printed by the master machine and the slave machine. , Position deviation will occur, so in the past, the operator often confirms the printed material through visual inspection. W...
