A method for forming an absorbent article including a first absorbent core and a second absorbent core which are superposed on each other, includes feeding a first supporting web along a first feed path in a first feed direction; placing a succession of first absorbent cores on the first supporting web at a preset spacing; feeding a second supporting web along a second feed path in a second feed direction; placing a succession of second absorbent cores on the second supporting web at the preset spacing; coupling the first supporting web to the second supporting web such that each first absorbent core is coupled to a corresponding second absorbent core in a composite web including the succession of first absorbent cores and the succession of the second absorbent cores interposed between the first supporting web and the second supporting web.

Method and unit for forming an absorbent article

Absorbent nappy/diaper pads composed of a first absorbent base material, and a second absorbent material consisting of superabsorbent polymer powders, are made by a unit () that comprises a conveyor () carrying the first absorbent material along a predetermined feed path (P), and a feed system () by which the superabsorbent polymer powders are released onto the feed path (P); the feed system () comprises a fixed duct () with an outlet () directed at the feed path (P), and a valve (), positioned along an intermediate segment of the duct (), by which the superabsorbent polymer powders are dispensed intermittently and controllably. The valve () comprises a rotating disc (), set transversely to the duct (), with an annular region () that revolves through a gap () in the duct () and presents at least one slot () delimited longitudinally, in the direction of rotation of the disc (), by a leading edge () and a trailing edge (); the radial dimension of the slot () increases progressively, at least along a part of the distance from the leading edge () toward the trailing edge ().

Unit for making absorbent nappy/diaper pads

Products are transferred in an automatic manufacturing machine by a unit () equipped with multiple transport heads (), and a drive system () comprising at least two transmission assemblies () by which the heads () are set in motion. The transport heads () are divided operationally into a first group () and a second group (), in which motion is induced by a respective first transmission assembly () and a respective second transmission assembly ().
