Dampening and bridging apparatus for a duplicating machine

摘要

A bridging roller is disposed between the upper form roller of the inking system and the dampening form roller of the dampening system. The bridging roller's mounting means are offset from the axis of rotation of the bridging roller such that selective orientation of the mounting means allows the system to be quickly and easily changed over between the integrated and segregated modes. In the dampening system the oscillating roller and form roller are supported on a pivotable support structure such that the dampening form roller can be moved out of engagement with the master cylinder and the oscillating roller can be simultaneously moved out of engagement with the metering roller to facilitate start up of the printer. When the rollers are in this start-up position the oscillating roller can be independently moved to a remote position to facilitate cleaning of the printer.
