Rotary printing machine with image cylinder - has holder frame with vertical supports having curved recesses for cylinder axle ends

摘要

The holder frame can be moved selectively into a frame on the printing machine so as to bring into operational contact the image cylinder on the support with the pressure cylinder located above it. The frame of the printing machine has transverse rails along which the frame can move. An end stop is provided on the machine frame between the rails and comprises an adjustable screw. The holder frame has laterally positioned rollers which contact the inner walls of the rails. At least one of the rollers is eccentrically mounted so as to effect a positive location of the holder frame relative to the rails.
