Abstract: A feeding unit for feeding a component of a hygiene absorbent article; the feeding unit has: at least one sucking-holding head, which is designed to receive and hold the component; a conveyor to cyclically move the holding head along an annular application path; an input station in which the holding head receives a corresponding component which is connected—without gaps—to a continuous web; a cutting station provided with a cutting device, which cuts the continuous web crosswise; and an output station in which the holding head releases the component; the conveyor has: an annular guide; a slide which supports the holding head and is coupled to the guide so as to freely slide along the guide itself; and a linear electric motor, which has a stator, which is arranged in a fixed position along the guide and a mobile slider which is electro-magnetically coupled to the stator so as to receive, from the stator, a driving force and is rigidly connected to the slide.

Abstract: The unit for feeding lateral flaps of a hygiene absorbent article having: an input conveyor of a first continuous strip; a cutting assembly provided with a receiving drum, of the first suction-pick up heads that hold the lateral flaps and which are mounted to as to be radially movable on the receiving drum, and at least one blade which cyclically cuts the first strip crosswise; a spacer assembly having a pair of spacer drums provided with second suction-pick up heads that receive the lateral flaps of the receiving drum; and an actuator system, which cyclically moves each first suction-pick up head radially between a radial pick-up position and a radial release position, in the area of an output station.
