Apparatus for controlling contact pressure between rotating members
First Claim
Patent Images
1. An apparatus for controlling a contact pressure between rotating members, comprising:
- a first rotating member;
a second rotating member applying the contact pressure to said first rotating member and having an end shaft portion;
a support member for supporting said second rotating member to be movable with respect to said first rotating member;
a driving means for moving said support member so as to adjust said contact pressure applied by said second rotating member to said first rotating member;
a plate-like member brought into contact with said end shaft portion of said second rotating member;
a sensor for detecting a displacement of said plate-like member to generate a signal;
a holding member for holding said plate-like member;
a machine frame for pivotally supporting said holding member;
a spring member for applying a biasing force to said holding member causing said plate-like member to be separated from said second rotating member; and
an adjusting member for moving said holding member against said biasing force of said spring member to position said plate-like member in contact with said second rotating member.

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.
