Facility for connecting up a printing medium for a working cylinder on a printing machine uses a switching facility to adjust raising and lowering pressures in working power lines for moving a printing plate changeover device.

摘要

Raising pressure adjusts via a switching facility in a working power line (29) for raising a protection device or a printing plate changeover device (16). Lowering pressure also adjusts in a working power line (32) for lowering a protection device or a printing plate changeover device. A filter-regulating element (34) is connected into the raising power line between a working cylinder (26) and pressure source (33).
