Abstract (en)
A printing machine has two printing cylinders (22) which are alternatively movable into and out of contact with the matter (12) to be printed. Both cylinders are drivable from the main drive (24) for the machine, and either can be engaged via a dog clutch (68,70) having a single tooth so as to fix the register between the main drive and the cylinder. An alternative drive (34,36,38,40,42,44,46) is used to bring the cylinder to slightly below its operating speed before engaging the dog clutch. Each cylinder is in contact with a common inking roller (16) when in its operative position, and there is also a common impression roller (14).
