Dampener activation apparatus and method

摘要

A dampener activation apparatus is disclosed for engaging and disengaging a dampener with a plate cylinder of a printing press and for engaging and disengaging a drive gear with a roller in the dampener. The drive gear is driven to rotate about a shaft supporting the roller by a press drive train. The drive gear is also axially moveable on the shaft to engage and disengage the form roller. A first actuator is mounted to a dampener side frame and configured to translate the drive gear on the shaft to engage and disengage the form roller. A second actuator is attached to the printing press and configured to engage and disengage the dampener with the plate cylinder. A compressed air supply is in fluid communication with and configured to control the first and second actuators.
