The process consists of initiating movement of eccentric around shaft, inducing a reciprocating motion in slider, which slides in supporting guide, by means of rollers rotating on shaft attached to slider which are permanently in contact with the external perimeter of eccentric. The reciprocating movement of slider causes the multi-thread spindle to continually enter and leave the multi-start nut mounted on the end of hollow half-shaft, inducing an equal alternating angular motion of toothed wheel.
