<p>A selecting device (1) having a conveyor (5) for receiving a succession of caps (2) - for sealed pourable food product packages - arranged randomly in two opposite input positions, and for transferring the caps (2) along a path (P) to an output station (7); a sensor assembly (8) for determining the position of each cap (2); and an expulsion assembly (9) located at the output station (7) and activated selectively by the sensor assembly (8) to expel from the conveyor (5) relative caps (2) in a first of the input positions; the path (P) having a U-shaped orienting portion (P2) along which the caps (2) fed to the conveyor (5) in a second of the input positions are turned over through 180 DEG into the first input position; and a first and a second air nozzle (33, 34) of the expulsion assembly (9) being located respectively upstream and downstream from the orienting portion, and being activated independently by the sensor assembly (8) to act on relative caps (2) facing the first and second air nozzle. <IMAGE></p> |
