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.

Abstract: A method for making absorbent sanitary articles whereby each absorbent article is provided with at least one pair of side tabs. The method includes the steps of feeding a single continuous web with a longitudinal axis towards at least one cutting station where the continuous web is divided, by a succession of cuts transverse to the longitudinal axis, into a first and a second series of side tabs, each of which has an asymmetrical shape and separately applying each rotated side tab of the first series and each side tab of the second series along a continuous strip of a material for making the absorbent articles, in such a way that each rotated tab of the first series is juxtaposed with a respective tab of the second series to define a respective pair of side tabs.

Abstract: A machine for making absorbent sanitary articles, where each article includes components progressively positioned relative to each other and assembled along a production line. The machine includes a programmable electronic controller device having a shift register, at least one optical inspection system connected to the programmable electronic controller device, and an operator interface connected to the electronic controller. The programmable electronic controller device generates a machine sync signal, a trigger signal for activating the optical inspection system in phase with the sync signal and a shift register shift command. The optical inspection system receives the trigger signal and has a defined maximum response time which produces at least one band of uncertainty. The operator sets with the operator interface the instant of activating the shift register shift command outside the band of uncertainty and between two consecutive sync signals defining a machine step.
