Abstract (en)
[origin: US4598640A] In a web-fed offset rotary press printing unit comprising four cylinders (2-5), in order to move the two inner cylinders, for instance blanket cylinders (3, 4), apart from one another without having to move the outer cylinders (2, 5), the cylinder trunnions (6, 7) of the inner cylinders (3, 4) are positioned on double eccentric bushes (8, 9; 10, 11). By means of tie rods (16-19), all the pairs of eccentric bushes (8, 9; 10, 11) are pivoted in common about the same angle, resulting in a linear movement in opposite directions (P or P') by the inner cylinders (3, 4) with respect to the straight line (G) on which the four cylinders are disposed.
