FROM CYLINDER OF A PRINTING MACHINE, COMPRISING A PLURALITY OF SECTIONS IN A SERIES IN THE AXIAL DIRECTION ON THE ENVELOPE SURFACE THEREOF, AND PRINTING COUPLE COMPRISING SUCH FORM CYLINDER

摘要

A forme cylinder of a printing machine includes a plurality of sections in series in an axial direction of the cylinder surface. At least one printing forme is arranged in each one of these sections. The forme cylinder has at least one channel, also extending in the axial direction of the cylinder. That channel has an opening on the surface of the forme cylinder. At least one holding device for each of the sections is arranged in this channel. Each such holding device can be pneumatically actuated in sections. At least one recess, open to the cylinder surface, is formed outside of these sections. A device that is usable to distribute compressed air to the respective sections of the forme cylinder is provided in this at least one recess. The device for distributing the compressed air is configured as a plurality of valves. At least one control device is provided outside of the forme cylinder and is used to activate the plurality of valves in a non-contact manner. The control device associated with each valve is oriented toward the surface of the forme cylinder and acts in a radial direction.
