Flexographic printing machine having common control means for rapid approach and disengagement of cylinders

摘要

A printing unit for a flexographic printing machine having an individual or sole impression cylinder (10) comprises a plate cylinder (9) and an inking cylinder (11) slidably mounted by means fo supports (16, 25) on a bed (2). In order to facilitate the displacement and the positioning of the cylinders (9, 10, 11) with respect to each other, it is provided for the supports (16 , 25), arranged on one and the same side of the longitudinal central plane of the continuous material to be printed, to be mounted on one and the same guide shaft (17) which is integral with the bed (2) and to ensure their displacement with the aid of common control means (36) for rapid approach and disengagement in order to obtain the engagement and the disengagement of the cylinders (9, 10, 11) with respect to one another.
