Abstract
The invention relates to a pressure-contact and lift-off arrangement, which comprises pressure-rollers, a doctor blade, and brushes, which are mounted in guide rails or bearings, as appropriate. These rails or bearings are located on the inner sides of the side plates of a processing unit. Hold-downs are mounted on supporting frames in a manner permitting vertical adjustment by means of screws. The supporting frames have elongated holes which are obliquely inclined, and are capable of displacement in the longitudinal direction over bearing carriers on which rolling-contact bearings seat. The bearing carriers are fastened to the side plates by means of screws. The supporting frames are connected by means of a shaft, which possesses hubs and on which a hand lever acts. The hubs are connected to link plates by means of attachment screws. Connecting links are mounted on these link plates by means of bolts which are capable of rotating. The connecting links are articulated to the supporting frames by means of screw-bolts. The supporting frames carry lift-off stirrups with cutouts for the drive rollers, and for the brushes. In the working position, the hold-downs press the pressure rollers, the doctor blade, and the brushes against a pressure plate, or against the surface of a table, over which the printing plate is guided.
