ABSTRACT:
An impression cylinder is adapted to be disengaged from a plate cylinder after an image area of printing plate attached thereon has passed through the contact point where the cylinders abut each other, but before the trailing end of an object that is printed will pass through said contact point. The disengagement as well as the engagement of said cylinders are controlled by means of a mechanism comprising scale disks each of which has an adjustable angle index and is driven to rotate synchronously with the plate cylinder.
