The flexographic printing machine with an impression cylinder mounted in a double-sided printing-machine frame and regulated to a constant operating temperature, and with several flexographic printing units, is characterized in that the printing-machine frame is temperature-stabilized at least in the projection range of the impression cylinder. It thereby becomes possible to guarantee a high printing quality, even without readjustment, after the operating temperature has been reached.

Flexographic printing machine with a temperature-regulated

Means for displacing elements, such as the rollers of printing machines, located between the upright frames of a pedestal machine. A rotatable drive shaft is supported in each of the frames parallel to the direction in which the displacement is to proceed, and is drive connected to the said elements. Adjusting shafts having hand wheels attached to their free ends and coupled to the drive shafts extend, when in working position, into the space between the upright frames. In rest position, they are displaceable out of said space, which is thereby cleared for access to the equipment.

Means for displacing elements between upright machine frames

A device for supporting a shaft, e.g., for the pressure roller of a printing machine, which is subjected to radial impact forces and which is slightly adjustable between a working position and a rest position. The shaft bearings are carried in bearing jewels guided in the bore of a fixedly arranged bearing block with the aid of a guide bolt. Two support surfaces for the bearing jewels are inclined relative to a plane which is perpendicular to the direction of adjustment of the shaft, and are pressed against corresponding support surfaces on the bearing block when the shaft is in working position.
