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.

Abstract: A device for applying pieces to absorbent articles includes a supporting shaft rotating an axis; anvils rotating about the axis; a cutting unit operating with an anvil contact surface defining a cutting station for cutting a web into pieces; pads, each having a retaining surface for a piece, are moved about the axis for conveying a piece from the cutting station to a releasing station for release onto a substrate. Each pad rotates for varying the orientation from the cutting station, where the larger side of the pad is parallel to feed of the web, to the releasing station, where the larger side of the pad is transversal to the feed of the receiving substrate, and vice versa. Each pad translates parallel to the pad axis, away from and towards the shaft axis. Each pad has an oscillating movement about its own axis.

Abstract: A device for applying segments of absorbent articles includes a cutting station for cutting a continuous web into segments and an applicator station for applying each segment on a respective absorbent article. A plurality of carrier units, each includes a pad for retaining and transferring a segment from the cutting station to the applicator station. The pad fully rotates about a main axis to transfer the segment from the cutting station to the applicator station and return to the cutting station and, from the cutting station to the applicator station, rotates at least 90° about its axis of rotation to orient the segment transverse to the feed direction of the absorbent article. A first movement member moves one or more first carrier units about the main axis and a second movement member moves one or more second carrier units separately from the first carrier units about the main axis.

Abstract: A unit for applying first and second tabs, obtained from first and second webs, to a chassis web includes an applicator drum rotatable about an axis and including a main body. A plurality of carriers is movable between a lowered position close to the axis and a raised position away from the axis, each including a suction portion. A first carrier first suction and non-suction portions aligned along the axis. A second carrier includes second suction and non-suction portions aligned along the axis. The first suction portions alternate with the second non-suction portions and the first non-suction portions alternate with the second suction portions. A first system holds the first web on the applicator drum upstream of a cutting device. A second system holds the second web on the drum upstream of the cutting device.
