ABSTRACT:
An apparatus for controlling a contact pressure between a plate cylinder and a form roller includes a roller arm, an actuator, a plate, and strain gauges. The roller arm supports the form roller to be movable with respect to the plate cylinder. The actuator moves the roller arm so as to adjust a contact pressure applied by the form roller to the plate cylinder. The plate is brought into contact with an end shaft portion of the form roller and supported on a machine frame. The strain gauges detect a displacement of the plate to generate a signal.
