<p>The sucker apparatus comprises a carriage (1) which moves along a guide rail (4) having a rectilinear or curved section. The carriage has a manual or motorised rotation system (6) on which is pivoted a translation system (7) for the longitudinal displacement of a bar (9). The translation system is controlled by a transfer system (8) and provided with uprights (10) forming supports for the suckers (11). The translation system comprises guide rollers with vertical axles rotated by an activating system. This system transmits the movement of a toothed crown wheel on the rollers, which meshes with racks fixed to the bar, which displaces in one direction or another . The uprights carried by this bar have a pivoted gripping system on the top of which are mounted the suckers and a lever. The lever is controlled by an activating system and connected in its vertical movement with a pivot movable inside a guide slot in one of the uprights. This allows the system to widen or narrow in the transverse direction relative to the upright.</p> |
