Abstract: A method and unit for orienting pump-operated caps, whereby a disorderly succession of caps, each having an elongated head and a draw tube extending from the head, is fed on a conveying surface to an engaging station. At the engaging station the draw tube of each cap is engaged by an orienting seat and an elastic cord. The seat is movable with respect to the elastic cord, and cooperates with the elastic cord to rotate the cap about a respective axis of rotation crosswise to the conveying surface, so as to impart a given orientation to the cap.

Abstract: The apparatus for feeding closures provided with a tube to an operating unit, has a rotatable disk-like body, having a substantially vertical axis and a fixed or movable wall which delimits the body peripherally. The disk-like body has a circular supporting wall which is permeable to air at an outer annular portion, and is provided with a peripheral annular track adapted to accommodate closures arranged with their tubes directed upward. A pump is provided and arranged below the supporting wall to direct a jet of air with a substantially vertical direction toward a portion of the lower surface of the supporting wall so as to lift the closures from the circular supporting wall and push them toward the peripheral annular track from which closures exit through a passage defined in the wall which delimits the disk-like body.

Abstract: Apparatus for correctly positioning dispensers to be applied to containers, wherein containers and dispensers are fed in succession to an aligning conveyor which comprises a plurality of housings adapted to receive respective dispensers and to support them rotatably about their respective axes. A fixed abutment element is arranged adjacent to the aligning conveyor and is adapted to interfere with a portion of the peripheral surface of the dispensers to cause a rotation of the dispensers about their respective axes during their movement on the aligning conveyor. A photocell is provided for sensing the position assumed by a given portion of each rotating dispenser, and suckers are also provided and controlled by the photocell in order to lock each dispenser within the related housing when a given position is reached.
