Abstract (en)
[origin: US4833982A] To provide for selective printing by a five-cylinder printing machine either in single prism printing (1/0) or double prime printing (2/0) or prime-and-verso printing (1/1), at least one (3) of the printing cylinders can be selectively positioned by a crank arrangement (16, 15, 15a) which is coupled to a link (13) which link, in turn, operates a lever of an eccentric bearing (12) such that when the first printing cylinder (3) is to be, selectively, in engagement with either the impression cylinder (1) or the second blanket cylinder (2), the link is in a position at which the link passes through the axis of rotation of the crank so that reactive rotary forces from the blanket cylinder will not be transferred to the crank and hence will be isolated from an operating element (18) which moves the crank arrangement. Preferably, the crank arrangement is formed by a gear segment (15) which is rotated by a segmental gear (16), coupled to a linear piston-cylinder arrangement forming the operating element (18).
