TRANSFERSYSTEM FUER LITHOGRAPHISCHE DRUCKPLATTEN.

摘要

The transfer device comprises orientating elements (2) for receiving a transvesely extending lithographic plate from the horizontal conveyor (1) and positioning a folded over end portion (12) of the lithographic plate in the path of a hook member (13) carried by an endless chain (30) of an elevator (3). The plate (S) is lifted into a vertical position and then deposited on a positioning bed (4). An upper part (23) of the bed is pivotable by means of a pneumatic or hydraulic cylinder (22) to position the end portion of the plate (S) inwardly of the locus of the hook member as the hook member passes around a lower sprocket wheel (15) of the elevator. The hook member passes by without again picking up the lithographic plate.
