Printing machine, incorporating at least one double deplacable cylinder.

摘要

The printing machine (press) according to the invention includes, for a given cylinder, first means for displacement from a first position, corresponding to the working position, into a second position, and second means for displacement from the said second position into a third position; the shaft (5) of this cylinder (3) includes an individual drive motor and gearwheels (6) at its two ends; the second displacement means comprise a set of two racks (15) in which the gearwheels (6) can mesh, so that the displacement of the said cylinder (3) from the second to the third position is obtained by virtue of the rotation of the motor for driving the shaft (5) of the said cylinder. This may be a machine with automatic changeover of screen rollers with at least two screen rollers (3, 3') with double displacement. It may be a machine with automatic washing of the plate cylinder with a counterpressure cylinder (2) with double displacement. <IMAGE>
