Abstract

A rotary printing machine includes a first gearwheel, a second gearwheel, and a setting device for selectively adjusting the second gearwheel into a first position, in which the gearwheels are coupled to one another, and into a second position, in which the gearwheels are uncoupled from one another. The printing machine includes a traction mechanism for securing a staggered-teeth rotary-angle position of the second gearwheel relative to the first gearwheel when the second gearwheel is adjusted into the second position, and a first tension element for tensioning a rotatably arranged traction means of the traction mechanism. The first tension element is loaded by a spring. The traction means is assigned a second tension element, and in the second tension element is mounted so to be a selectively adjustable into a first switching position and a second switching position.
