Multicylinder rotary printing machine - has hydraulic cylinders to raise and lower counter rollers mounted on hinged arms

摘要

The paper (1) passes over a number of rollers in the printer. The machine has a number of printing heads (5, 6) arranged in series on the same axis. Each head carries the required number of blocks (7, 8) which come into contact with the rollers (9, 10). These rollers come into contact with the paper with the movement of the rollers (13, 14) under the paper. These rollers are mounted on lever arms (17, 18) connected by hydraulic cylinders. The machine is controlled through a coder (26).
