Abstract: Containers are directed onto a carousel rotatable as one about a vertical axis with a tank affording a fluid-tight enclosure and equipped with filler valves, each positionable over the mouth of a relative container; the tank is filled with a liquid substance until a given head has been established, whereupon the enclosure is negatively or positively pressurized, according to the type of liquid substance being handled, in such a way that the jet formed at the outlet of the filler valves will be dispensed at a selected discharge pressure different to the pressure deriving solely from the head of the liquid substance in the tank. The tank is depressurized when filled with foamable liquid substances, and pressurized when filled with viscous substances.

Abstract: Absorbent pads passing along a feed path advance first on an infeed conveyor at a first pitch and a first velocity, then on an outfeed conveyor at a second pitch and a second velocity. The transfer from infeed to outfeed is effected by means of a head disposed between the two conveyors, rotatable about a vertical axis and carrying at least one handler unit equipped with a suction cup coupled to an epicyclic train inside the head and made to orbit around the axis following a looped trajectory; the head also comprises a cam and rocker mechanism operating in conjunction with a lever mechanism by which the suction cup is lowered and raised in a direction parallel to the axis of rotation when passing through points at which the pads are picked up from the infeed conveyor and released onto the outfeed conveyor, respectively. Being adjustable, the cam and rocker mechanism also provides means by which to vary the positions of the pickup point and the release point.
