Abstract: An apparatus and method for facilitated automatic washing and rinsing of previously used lithographic plate members having substantially flat central portions and pre-formed parallel flanged peripheral edges which comprises removing one or more used plates from a press plate drum, placing the plate on a feed fixture, longitudinally propelling the plate member, applying one or more cleaning solvents to the surface of the plates, scrubbing the surfaces of the plates, rinsing the surfaces thereof with one or more solvents, removing of excess rinse liquids from the surfaces of the plates, sealing the surfaces with a water soluable preserving substance and storing of the plate members until reuse thereof, while accommodating and preserving the peripheral pre-formed flanges of the lithographic plates as they pass through the apparatus, and recycling the cleaning solvent.

Abstract: A method of recovering ink deposits which remain in the ink drum liner of a substantially empty container which comprises the steps of positioning the mouth end of the drum liner proximate to a roller nip region of wringer assembly structure, inserting the mouth end into the wringer assembly, rotating the wringer assembly so as to draw the liner therethrough while simultaneously urging the ink remaining in the liner towards the closed end as a bulge, pulling the liner through the wringer assembly, opening the closed end of the liner to release the bulge of remaining ink deposits from the closed end of the liner, releasing the accumulated ink deposits from the liner and removing the ink drum liner from said wringer assembly structure.

Abstract: Stacking apparatus for generally flat objects, particularly useful for the stacking of magazines by zip code. According to the invention, a continuous input stream of the objects is alternately diverted in preselected numbers pursuant to a shift signal to first and second hoppers or bins wherein the objects are deposited in stacks, the stacks when completed being alternately ejected from the hoppers onto common conveyor means whereon they are merged into a single output series of stacks.In one form of the invention an input feeder receives the output flow of magazines from a labeler; a vertically shiftable separator alternately directs sequences of the generally flat objects to upper and lower feed conveyors which in turn alternately feed the sequences of objects to side-by-side hoppers. "Live" rollers moving at right angles to the feed conveyors underlie and extend as stack output conveyor means from the hoppers.
