ABSTRACT:
A cylinder of a rotary printing machine having an inner cylinder body includes an elastically deformable cylinder jacket formed as part of a circle, the cylinder jacket being substantially intrinsically rigid, and an adjusting device for acting upon the elastically deformable cylinder jacket so as to vary the outer diameter thereof, the adjusting device having a positioning part supported on and radially displaceable relative to the inner cylinder body for shifting the cylinder jacket jointly therewith in the same radial direction, and having a force deflector displaceable over a positioning travel distance derivable from the radial displacement of the cylinder jacket for acting upon the cylinder jacket so as to deform it.
