Abstract: A forming pocket suitable for forming conglomerates from particulate material to be used as an absorbent padding for hygienic products, includes an external forming substrate for receiving particulate material, the substrate having openings and a shape conjugated to a form of the absorbent padding to be made. The forming pocket includes a grid supporting structure, which has openings and is coupleable with the substrate to support the substrate during suction of particulate material through the substrate. The supporting structure has an external surface configured to contact the substrate and has a shape conjugated to the shape of the substrate. A method of making the forming pocket includes obtaining from at least one first metal sheet first and second sets of elements having a plurality of cuts, and wedging the elements of the first set with the elements of the second set via the cuts to make the grid supporting structure.

Abstract: A method for making sanitary articles, includes: feeding along a longitudinal direction of movement a first web of material defining a main body of the article; feeding a pair of longitudinal strips; dividing each strip into a succession of trapezoidal pieces adjacent each other and each having a long base and a short base so the pieces of each strip can be divided alternately into first pieces having a first orientation and second pieces having a second orientation opposite to the first orientation; spacing the pieces of each strip from each other; rotating the first or second pieces of each strip by 180° in plane to give the pieces of the first strip the first orientation and the pieces of the second strip the second orientation; applying each piece on a first face so the long base protrudes laterally from the edge of the first web.
