Abstract: An apparatus for distributing particulate material on a conveyor movable along a respective operating direction includes: a tank containing particulate material and equipped with feed means for feeding the particulate material; and distribution means located downstream of the tank to receive the particulate material and the particulate material on the conveyor. The distribution means include a diffuser element and a vibrating device to shake the diffuser element. The diffuser element extends with its sliding plane along its axis between an infeed portion to receive a preset flow quantity “Q” of particulate material, and an outfeed portion. The diffuser element includes a transversal partition at a predetermined distance from the sliding plane to form a neck which acts in combination with a vibration imparted by the vibrating device to distribute the particulate material along a predetermined width of the outfeed portion.

Abstract: A rotary device for welding a continuous web comprises a rotary unit rotating about a respective axis and welding units for welding the web mounted, angularly spaced, on the rotary unit. A movement device varies a radial position of the welding units. First and second supporting elements supporting the web are disposed, respectively, upstream and downstream of respective ones of the welding units, to keep the web tensioned when the respective welding unit is at an operating position. The first and second supporting elements are supported by a load-bearing structure connected to the welding units in such a way that a radial movement of the welding units corresponds to a movement of the first and second supporting elements towards and away from the axis.

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.
