Abstract (en)

A flexographic colour assembly designed to be arranged at a print drum, comprising a screen roller and a plate-carrying roller, supported at its ends on skids that can be moved in parallel and independently between three positions: one rest position distant from the printing drum, one working or attachment position, where the screen roller is positioned in contact with the plate-carrying roller, and the plate-carrying roller is shifted into contact with the printing drum, and a detached position in which the plate-carrying roller is shifted a pre-established short distance from the contact with the printing drum, and the screen roller is shifted a short pre-established distance from contact with the plate-carrying roller, said plate-carrying roller having side and longitudinal rollers to adjust its positioning with respect to the printing drum. The colour assembly comprises a single drive motor (17) for its movement between said rest position and working position of said screen rollers (2) and plate-carrying rollers (3), and, for driving said plate-carrying roller side and longitudinal registers, motion transmission means between said motor (17) and said support slides (5a,5b) and longitudinal support skids and said side and longitudinal registers and a pair of actuators (50a,50b) to control a respective attachment-detachment movement of the screen roller (2) and plate-carrying roller (3) independently from the motor (17) and a control unit (54). <IMAGE>
