ABSTRACT:
A cylinder in a rotary printing press is coupled to a driving wheel or gear by the engagement of two coupling disks. One of the disks is shiftable into coupling engagement with the other disk by application of a pressure medium to a work cylinder. A control valve is carried by the shiftable disk and limits the force of the pressure medium by use of a bleed passage that is closed only when coupling has been accomplished. The force of the pressure medium is at a higher level when coupling has been fully completed.
