Epicycloidal vibrating device, characterised in that it comprises a shaft (3) rigidly fastened at one of its ends (11) to a plate (4), connected by elastic means (6) to the frame (1) of the machine, and furthermore supporting a thermoplastic piece (14), the said shaft (3) being provided near this end (11) with a magnetic excrescence (8), the rotation of which, within a plurality of magnetic fields created by the energisation of a plurality of electromagnets (7) arranged around the said shaft (3), generates an epicycloidal-type movement of the plate (4), the other free end (12) of the shaft (3) being, on the one hand, rotationally guided within the frame (1) of the machine and, on the other hand, rotationally driven by a motor (2). <IMAGE> |
