ABSTRACT:
A printing unit is guided along a straight line in parallel relation with the printing plane of a printing support. A device is arranged to pivot the printing unit between at least two printing supports spaced angularly apart. The device includes a coupling assembly interconnecting the printing unit with a drive member. A part of the coupling assembly includes a slotted crosshead or plate in which rollers move through branch slots disposed angularly to one another. Due to the guidance afforded the printing unit as it is pivoted between different angularly spaced printing supports, it moves along a curve significantly flatter than the arc of a circle on which the printing planes of the printing supports are located.
