A finishing gear train, formed by a drive pinion (15), comprises a center driving gear (13) engaged with a transmission wheel (10) rotatably secured to the barrel arbor. The gear is rotatably mounted on a frame according to a rotation axis vertically adjacent to the drum in the direction of thickness of the movement so as to define a secondary level.</p> |
