PRINTING UNIT WITH A BLANKET CYLINDER MOVABLE BETWEEN CYLINDER CHANGE-IN POSITION AND CYLINDER CHANGE-OUT POSITION AND CORRESPONDING PRINTING MACHINE

PROBLEM TO BE SOLVED: To facilitate cylinder transfer movement between cylinder change-in position and cylinder change-out position in the printing machine. SOLUTION: On the frame 25, the first printing group 7A consists of the first plate cylinder 9A having the axis line A9A and the first blanket cylinder having the axis line A11A and incorporated with an impression cylinder 11B, and the mechanism 23A for supporting the first blanket cylinder 11A makes the first blanket cylinder 11A move relative to the frame 25 in between at least one cylinder change-in position where the first blanket cylinder 11A is pressed onto the fist plate cylinder 9A and onto the impression cylinder 11B and the cylinder change-out position from where the fist blanket cylinder 11A leaves from the first plate cylinder (9A) and the impression cylinder 11B, and the supporting mechanism 23A has at least one main joint rod 33A which can be moved against the frame and supports the blanket cylinder 11A.
