Abstract: An absorbent element for the absorption of body fluids in sanitary articles comprises a first layer of sheet material presenting an array of hollowed formations (16) with respective mouth parts, as well as masses (18) of superabsorbent material that is able to expand as a result of the absorption of body fluid, which are set in the aforesaid hollowed formations (16). A second layer of sheet material (12) is applied on the first layer of sheet material (10) so as to cover the mouth parts of the hollowed formations (16). At least one of the layers of sheet material (10, 12) is permeable to body fluids to enable the body fluids themselves to penetrate into the hollowed formations and be absorbed by the masses of superabsorbent material (18) that expand in the hollowed formations (16), creating a first level of absorption of body fluids.

Abstract: A closure element (10) with elastic side panels for absorbent pant-like sanitary products (52), said element (10) being formed starting from a strip (12) at least partially made of elasticised material (16) folded in transverse direction so as to form two parts (22, 24), symmetrical relative to a central transverse plane (26), each of said parts (22, 24) being able to form a side panel (76) of an absorbent sanitary product (52), said closure element (10) comprising: —a first branch (28) that extends continuously through said central transverse plane (26); —two second branches (30) connected to respective opposite ends of the first branch (28) by means of respective first folds (32), distal relative to said central transverse plane (26), in which the first branch (28) and the two second branches (30) have respective mutually facing surfaces (34, 36) permanently fastened to each other; —two third branches (40) connected to respective ends of second branches (30) by means of respective second folds (42), proxima

Abstract: A pre-fastened absorbent sanitary product of the “training pant” comprises two end parts and a crotch portion extending between the two end parts. The two end parts have, on opposite sides of the product, pairs of homologous facing side edges connected together by respective fastening assemblies so as to define the waist line of the product. At least one, and preferably both of said fastening assemblies, are located at the outer side of the product flush to said outer surface in the absence of appreciable protrusions therefrom.

Abstract: A stack of interleaved laminar products comprises a first and a second array of products, each of which has at least one branch interleaved with a corresponding branch of at least one product in the other array. The products are folded into a generally W-shaped profile comprising two outer branches and two inner branches, with the distal edges of the said outer branches projecting at least partially beyond the said inner branches, so that the said distal edges can be used for interleaving with at least one other product in the stack.

Abstract: A process for making packs of interleaved laminar articles, comprising the operations of: providing a first plurality of strips of laminar material, subjecting these strips to a first interleaving operation so as to create a composite strip having an interleaved structure in which the strips located at terminal positions have corresponding outer limbs which project with respect to the said composite strip, cutting the composite strip into lengths through a transverse cutting operation so as to give rise to successive separate lengths of the said composite strip, and subjecting a second plurality of the said pieces to a second interleaving operation performed by making use of the said projecting limbs so as to give rise to a further composite strip comprising interleaved strips in a number identified by the product of the said first and the said second pluralities.
