Abstract: A machine for making absorbent sanitary articles includes a device for feeding a continuous strip to a conveyor roller and to a device for cutting the strip into first and second pieces. A unit forms and applies at least a pair of first and second pieces, aligned and spaced by a distance (d), for each absorbent article A first and a second roller each comprising a plurality of units pick up and successively release of first and the second pieces. A plurality of concentric units rotating, independently of each other, about a shared axis of rotation, each carries at least one unit. A motor defines a respective law of motion for each of the units and a mechanism translates the units, between a position for picking up the pieces, at the conveyor roller, and a position for releasing the pieces, at the forming and applying unit.

Abstract: In a method for making absorbent sanitary articles, each absorbent article includes a pair of side tabs fed from a single continuous tape divided by oblique cuts into first and second series of side tabs oriented in opposite directions. The side tabs of the first and second series are then fed along a first path and along a second path, respectively and are first rotated by 180° and then combined and transferred separately along a third, common path along which each tab of the first series has a respective tab of the second series placed alongside it to form a pair of side tabs. At least one of the side tabs of each pair is moved sideways such that each pair of side tabs is applied to a continuous web of material at a predetermined spacing.

Abstract: A device for processing a web of material for making nappies includes a rotary shaft having a first axis, a plurality of pads for receiving and holding the web. The pads are rotatable about the first axis and are movable relative to the first axis during operation. A plurality of anvils, each interposed between two consecutive pads, are connected with the rotary shaft and are rotatable with it about the first axis. A unit acting in conjunction with the anvils cuts the web into lengths. A first motor is mounted inside the device and connected to the pads to translate the pads along a radial direction at right angles to the first axis and a second motor is mounted inside the device and connected to the pads to rotate the pads about a second axis coinciding with the radial direction.

Abstract: A method and apparatus for depositing discrete elements on a support element. The discrete elements may be separated from each other or joined to form a continuous web. The discrete elements are fed into a pick-up station defined at a rotor which includes circumferentially adjacent pick-up members. Each discrete element is associated with a respective pick-up member having a first orientation with respect to a respective second axis of rotation. Each pick-up member is moved along the rotation direction towards a release position downstream with an at least partially accelerated or decelerated motion. Each pick-up member is rotated about the respective second axis of rotation until it takes, at the release position, a second orientation. Each discrete element is released on a support element at the release position. Each pick-up member is subsequently moved towards the pick-up station with an at least partially decelerated or accelerated motion.

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.
