ABSTRACT:
A method and apparatus for supplying a liquid medium, such as viscous printing ink, to the distributor and transfer rollers of printing machines. The apparatus includes an arcuate shaped distributor plate, an ink feed for dispensing a controlled quantity of liquid medium onto the distributor plate, and a feed roller that is mounted for cyclic movement in a path whereby it is rolled on the distributor plate to mix and uniformly spread the medium along the plate and about the periphery of the feed roller and then is moved into contact with the machine distributor roller to transfer the liquid medium thereto in a controlled manner. In one embodiment, the feed roller is moved in a cyclic circular path so that it first engages the distributor plate and then the distributor roller, and in another embodiment is moved in a reciprocating manner back and forth on the distributor plate and then engages the distributor roller. The ink feed is adapted to dispense controlled quantities of the liquid medium onto the distributor plate in timed relation with the cyclic feed roller movement.
