ABSTRACT:
A web drive control apparatus for continuously driving a web at a constant speed and stopping it at a desired position along a web drive line, comprises a web surface inspector for detecting a predetermined significant surface condition of a surface of the web. This inspector outputs an appropriate electric signal as a timing signal and a drive controller causes the web drive to start a deceleration of the web upon receiving the timing signal so as to stop part of the web where the significant surface condition is detected at a predetermined station along the web drive line. An activator, which is manually turned on and off, is provided to provide the line controller with an activation signal to enable the line controller to perform the decleration of the web.
