エブの位置制御装置。[Claim for Utility Model Registration] It has a web moving cylinder, detects the edge position of the running web using an optical sensor, and opens and closes a servo valve for the web moving cylinder using an electrical signal output from the optical sensor. In the web position control device that controls the edge position of the web by controlling the operation of a web moving cylinder, the optical sensor includes a first optical sensor that slightly opens the servo valve; It consists of a second optical sensor that fully opens the servo valve.From the position where the edge of the web comes off to the vicinity of the set position, the second optical sensor detects the edge position and fully opens the servo valve to operate the web moving cylinder. When the edge of the web moves from near the set position to the set position, the first optical sensor detects the edge position and slightly opens the servo valve to operate the web moving cylinder. Control device.
