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.

Abstract: A method for forming an absorbent article including a first absorbent core and a second absorbent core which are superposed on each other, includes feeding a first supporting web along a first feed path in a first feed direction; placing a succession of first absorbent cores on the first supporting web at a preset spacing; feeding a second supporting web along a second feed path in a second feed direction; placing a succession of second absorbent cores on the second supporting web at the preset spacing; coupling the first supporting web to the second supporting web such that each first absorbent core is coupled to a corresponding second absorbent core in a composite web including the succession of first absorbent cores and the succession of the second absorbent cores interposed between the first supporting web and the second supporting web.

Abstract: A method for making absorbent sanitary articles whereby each absorbent article is provided with at least one pair of side tabs. The method includes the steps of feeding a single continuous web with a longitudinal axis towards at least one cutting station where the continuous web is divided, by a succession of cuts transverse to the longitudinal axis, into a first and a second series of side tabs, each of which has an asymmetrical shape and separately applying each rotated side tab of the first series and each side tab of the second series along a continuous strip of a material for making the absorbent articles, in such a way that each rotated tab of the first series is juxtaposed with a respective tab of the second series to define a respective pair of side tabs.
