DRIVING MECHANISM IN OFFSET PRINTING MACHINES FOR AXIAL DRIVING IN THE FIRST ROLLER OR FIRST AND SECOND ROLLS OF A REPOSITABLE ROLLER PAIR

摘要

In order to provide a drive mechanism for the axial reciprocating movement of a first or a first and second roller of a pair of rollers which can be assigned optionally to the first ink grinding cylinder of an inking unit or the last application roller of a damping unit of a combined damping and inking unit, a lifting coupling of the full floating axle (13) of the first roller (3) with the first ink grinding cylinder (8) is provided. Said lifting coupling is passed onto the full floating axle (12') of the second roller (4') only when the rollers (3, 4') rest jointly on the forme damping roller, while, in the connecting position of the second roller (4) between the damping and inking unit, its full floating axle (12) is fixed axially and is separate from the lifting coupling. …IMAGE…
