Convertible moisture/ink system in printing or duplicating machines

摘要

A conversion system for readily changing a printing couple of a printing or duplicating machine between a separated system wherein moisture and ink are distributed to a master cylinder through separate paths and an integrated system wherein the moisture and ink are mixed in common paths to the master cylinder. A transfer roller of the main ink distribution system is bodily movable into and out of rolling contact with a moisture form roller of the main moisture distribution system to convert between the integrated and separated systems. The transfer roller is journalled on the machine and is so moved without removing or disconnecting the transfer roller. The driving connection of another transfer roller in the moisture feeding system is selectively switchable to change the location of slippage between the rollers in the moisture feeding system.
