A device converts the continuous rotary motion of a drive shaft into the intermittent rotary motion of a driven shaft, in particular with intermittent rotations of an amplitude of 180 DEG . The device comprises a plate keyed to the driven shaft, one side of which is provided with a plurality of movement elements spread over a given circumference, and a drum whose axis is perpendicular to the axis of the plate, keyed to the drive shaft and provided peripherally with a plurality of tracks. The tracks engage the movement elements, during the rotation of the drum, alternately, in pairs, on the opposite sides of one and the same movement element and, individually, on subsequent pairs of movement elements. |
