For printing machines furnished with a Direct Imaging system for preparation of printing plates there is designed an equipment, comprising an auxiliary drive unit (23) coupled with the plate cylinder (1), which is coupled with the gear wheel assembly by disenagageable coupling means. In the preferred embodiment the plate cylinder (1) is at one end accommodated in a bearing (27) of a print unit side wall (4) by means of a carrier (3) which is axially shiftable seated at the neck (2) of the plate cylinder (1) and is in a direct engagement with the plate cylinder (1). The carrier (3) is further by means of a belt drive coupled with an auxiliary drive unit (23) and by an electrically operated clutch (7) with an output wheel (6) of the gear wheel assembly. In another preferred embodiment the plate cylinder (1) is furnished with a mechanism for angular displacement and a mechanism for axial shift.
Equipment for driving plate cylinders of a printing machine furnished with a Direct Imaging System, the plate cylinders being coupled on the one hand with a central drive unit by means of a driving gear wheel assembly with disengageable coupling means and on the other hand with an auxiliary drive unit, characterised in, that the plate cylinder (1) is at one end accommodated in a bearing (27) of a print unit side wall (4) by means of a carrier (3) which is axially shiftably seated at a neck (2) of the plate cylinder (1) and is in a direct engagement with the plate cylinder (1), the carrier (3) being coupled with the auxiliary drive unit (23) by means of a belt drive and with an output wheel (6) of the gear wheel assembly by means of an electrically operated clutch (7), the clutch (7) engaging with the output wheel (6) and a driven pulley (8) of the belt drive.
