The compressive action is realised by inflicting a nutational motion on an inner cone (mantle) while an outer cone (concave) remains fixed. The nutational motion is actualised by an eccentric bushing transferring the rotational motion of the drive shaft via a gear ring to the main shaft, see Fig. 1.The mantle is allowed to rotate freely around the …
