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.

Abstract: A forming pocket suitable for forming conglomerates from particulate material to be used as an absorbent padding for hygienic products, includes an external forming substrate for receiving particulate material, the substrate having openings and a shape conjugated to a form of the absorbent padding to be made. The forming pocket includes a grid supporting structure, which has openings and is coupleable with the substrate to support the substrate during suction of particulate material through the substrate. The supporting structure has an external surface configured to contact the substrate and has a shape conjugated to the shape of the substrate. A method of making the forming pocket includes obtaining from at least one first metal sheet first and second sets of elements having a plurality of cuts, and wedging the elements of the first set with the elements of the second set via the cuts to make the grid supporting structure.

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 machine for making absorbent sanitary articles including an absorbent pad with at least one discrete layer of superabsorbent polymer material includes a unit for forming and applying a succession of absorbent pads, which includes a drum for forming the pad, a duct for feeding a charge of superabsorbent polymer material to the drum and intermittent valve mounted along a stretch of the duct and driven by an actuator. A device detects the superabsorbent polymer material and sends a signal to a control and drive unit connected to the device indicating that the superabsorbent polymer material has been detected. The control and drive unit is configured to drive the actuator to bring the valve into phase with the rotation of the drum when the deviation of the signal from a reference signal exceeds a defined threshold value.
