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.

An absorbent body forming satisfactory connections while webs are conveyed at a high speed includes at least two sheets of nonwoven fabric overlapping each other; connections at which the nonwoven fabric sheets are connected together; and an absorbent material disposed between the nonwoven fabric sheets at a small region encircled by the connections. When seen in a direction perpendicular to a main surface of the nonwoven fabric sheets, a plurality of the connections is formed with spaces therebetween on each side of imaginary polygons compartmentalizing the nonwoven fabric sheets and neighboring each other, and the connection is formed at least on a middle part of the sides common to the imaginary polygons neighboring each other. The connections are formed sequentially, and simultaneously arranged in a row parallel to each other, and the minimum number of connections per row is at least 45% of the maximum number of connections per row.

An absorbent core comprising substantially continuous zones of one or more high fluid distribution structures and discontinuous zones of fluid absorption structures surrounding the one or more high fluid distribution structures, wherein the one or more high fluid distribution structures are arranged to distribute fluid across the absorbent core at a speed that is faster than the speed of fluid distribution across the absorbent core by said discontinuous fluid absorption structures, and wherein said continuous zones extend along a path that is substantially parallel to at least a portion of the perimeter of the core, said portion of the perimeter of the core comprising at least a portion of the sides of the core and one of the ends of the core.

An absorbent article having a main body having a liquid-permeable topsheet, a liquid-impermeable backsheet and an absorbent core sandwiched between the topsheet and the backsheet is disclosed. The main body has longitudinal and transversal axes. The article has two wings extending asymmetrically outwardly from a crotch portion of the main body in opposite directions with respect to the longitudinal axis. The wings are provided with means for fastening them to a garment when folded over the main body and towards the longitudinal axis. Each wing has an outer edge which defines at least one arc of a circle having a radius coinciding with a section of the outer edge. The section extends between a first point and a second point along the outer edge where the arc no longer coincides with the outer edge. The radius is between 40-500 mm. Also disclosed is a method for manufacturing the absorbent article.

An absorbent member manufacturing method of the present invention is a method for manufacturing an absorbent member (100) for an absorbent article and including synthetic fibers (10b) and hydrophilic fibers (10a). The method involves: a transporting step of transporting the hydrophilic fibers (10a) and a plurality of sheet fragments (10bh) to an accumulating depression (41) by using a duct (3); an accumulating step of accumulating, in the accumulating depression (41), the plurality of sheet fragments (10bh) and the hydrophilic fibers (10a), and obtaining an accumulation (100a) which is a constituent member of the absorbent member (100); and a depression forming step of forming a depression (100e) in the accumulation (100a) by applying pressure to a portion thereof. In the transporting step, the sheet fragments (10bh) and the hydrophilic fibers (10a) are brought into contact with one another in an airflow created inside the duct (3), and the sheet fragments (10bh) and the hydrophilic fibers (10a) are transported by the airflow in a dispersed and airborne state in which the sheet fragments and the hydrophilic fibers are mixed.

An absorbent article having a main body having a liquid-permeable topsheet, a liquid-impermeable backsheet and an absorbent core sandwiched between the topsheet and the backsheet is disclosed. The main body has longitudinal and transversal axes. The article has two wings extending asymmetrically outward from a crotch portion of the main body with respect to the longitudinal axis. The wings each have a means for fastening them to a garment when folded over the main body towards the longitudinal axis. The fastening means for each wing are offset from each other in the longitudinal direction. A method for manufacturing the absorbent article is also disclosed.

A method of making an absorbent article having a longitudinal axis and a transverse axis is provided. The method involves delivering a supply of absorbent web in a machine direction and cutting the absorbent web material in a cross-direction to form a repeating nested pattern of generally identically shaped and oppositely oriented absorbent cores that are asymmetrical about the transverse axis. The cut absorbent cores are then positioned between a continuous web of topsheet and backsheet material, wherein the absorbent cores remain in the cross-direction and are spaced apart in the machine direction. Absorbent articles are then stamped out in the cross-direction, wherein adjacent absorbent articles have alternately oriented absorbent cores.

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.
