To provide a rotary press which prevents the disadvantages in the operation of a conventional device from influencing the function of the former and positively realizes the sophisticated operating with ease and precision.

This rotary press, especially a rolled paper rotary press has at least one printing press, which has, in turn, a plurality of printing device cylinders 2. In addition, at least, one of the printing device cylinders 2 is functionally connected to or disconnected from at least, one functional linkage machine 3 provided for fulfilling a function required for operating the printing device. Further, the functional linkage machine 3 is equipped with a drive device 5 and supported by a linear guide device 4. In this rotary press, the functional linkage machine 3 has a positioning device 11 equipped with a control device 12 and the control device 12 receives at least one signal which is generated by detectors 21 and 23 installed at the functional linkage machine 3 and based on a position. Thus the operation of the rotary printer is highly facilitated and its operating precision is increased by controlling the drive device 5 with the help of the controller 12.
