ABSTRACT:
A device for manipulating sleeves, including sleeves serving as printing forms or as rubber blankets as well as screened sleeves, from outside the printing mechanism without removing the paper web which has been drawn in. The device includes a sleeve gripping system associated with each cylinder intended to receive a sleeve. A force mechanism is activated by this sleeve gripping system to grip the sleeve within the printing mechanism in a frictional or positive engagement. When gripped, the respective sleeve can be displaced on the cylinder in the axial direction in a correctly positioned manner by the gripping system at least between the side walls of the printing mechanism.
