Summary:A rotary press, especially for preparing tablets, with a frame, a rotor with drive, at least one pressure roller unit, and a housing. To improve the absorption of the forces introduced into the pressure roller unit, of which there is at least one, and to design the rotary press as a low-vibration and low-noise press, a massive base plate (1) accommodating the rotor (2) with the drive and the pressure roller unit (3) is supported by the base frame (6) by elastic mounts (7). The rigidity of the elastic mounts (7) and the mass of the assembly unit formed by the rotor (2) with the drive and the pressure roller unit (3), of which there is at least one, are coordinated with one another such that the natural frequency of this vibration system in all six possible degrees of freedom is substantially lower than the lowest punch engagement frequency occurring at the lowest speed of rotation, which is the excitation frequency.
