Abstract
The path changing rotational conveyor for lightweight articles includes a rotor with receiving configurations distributed along its periphery to be coupled with the lightweight articles and a perimetric wall with a plurality of suction openings in correspondence with the receiving configurations; and a stationary negative pressure chamber defining a laterally open channel facing the perimetric wall of the rotor along a predetermined circumferential arc. The negative pressure chamber is partly delimited by the perimetric wall of the rotor and, when the rotor rotates, the suction openings are communicated directly with the negative pressure chamber along the predetermined circumferential arc. The rotor is connected to a rotation device and the chamber is communicated with a suction source.
