Abstract:
A machine for making sanitary articles including an impermeable outer layer and an absorbent pad superposed thereon, the machine including a feed line feeding the outer web and a unit forming the absorbent pad. The forming unit includes a first feeder feeding a first web along an operating direction, a second feeder feeding a second web, a coupling station coupling the first web to the second web, a dosing/depositing station located upstream of the coupling station where a distributed quantity of absorbent material is placed on the first web. The dosing/depositing station includes an apparatus for distributing particulate material with a tank containing particulate material, a feed mechanism feeding the material and a downstream distribution mechanism receiving the material to distribute the material on a drum or conveyor. The distribution mechanism includes a diffuser and a vibrating device to shake the diffuser.

Claim (Index 16):
A machine for making absorbent sanitary articles comprising at least an impermeable outer layer and an absorbent pad superposed on the outer layer, where the machine comprises at least a feed line for feeding the outer web and a unit for forming the absorbent pad, the forming unit comprising:\n first feed means for feeding a first web of non-woven fabric along the operating direction at least partly defined by drum or conveyor movable along a respective operating direction; second feed means for feeding a second web of non-woven fabric; a coupling station for coupling the first web to the second web of non-woven fabric; a dosing and depositing station, which is operatively located upstream of the coupling station and where at least one distributed quantity of absorbent polymer material is placed on the first web of non-woven fabric; characterized in that the dosing and depositing station comprises an apparatus for distributing particulate material comprising: at least a tank containing particulate material and equipped with feed means for feeding the particulate material; distribution means located downstream of the tank to receive the particulate material from the feed means and configured to distribute the particulate material on the drum or conveyor; wherein the distribution means comprise at least a diffuser element and a vibrating device configured to shake the diffuser element, where the diffuser element extends with its sliding plane along its axis between an infeed portion of it, facing the feed means to receive a preset flow quantity of particulate material, and an outfeed portion of it, of predetermined width, which can be positioned to face the drum or conveyor; the diffuser element being equipped, at an intermediate position between the infeed portion and the outfeed portion, with at least one transversal partition at a predetermined distance from the sliding plane in order to form a neck which acts in combination with a vibration imparted by the vibrating device in such a way as to distribute the particulate material along the predetermined width.
