Abstract: A process for the continuous manufacture of articles of hygiene such as nappy-pants, of the type comprising an absorbent pad arranged between a liquid-impervious outer sheet and a liquid-permeable inner sheet, characterised in that absorbent pads are deposited at intervals onto a liquid-permeable continuous strip unwound from a reel in that a film of plastic material is extruded and deposited in the state where it has not yet solidified onto the strip and onto the pads, by applying the film against the strip and against the pads to make it adhere thereto and in that, after solidification of the film, a composite strip is cut transversely in the region situated between the absorbent pads, into individual articles.

Abstract: Adhesive is intermittently coated onto an elastic strip 4 which then passes over a grooved pulley 9 mounted on a slide or carriage 10 able to move intermittently on a slideway 11. A continuous flexible sheet consisting of a moisture-impermeable heat-sealable material is unreeled over the periphery of a rotary drum 3. The point of contact between the elastic strip 4, and the travelling impermeable sheet 2 is moved periodically in a direction transverse to the direction of travel of the sheet 2. This results in laying, along a curved path 4a of, a stretched elastic adhered to sheet 2. It is thus possible to make diaper units comprising crotch elastics edging the curvilinear profile of the leg openings or cut-outs.

Abstract: Absorbent pad of triple thickness in the between-the-legs zone (7) and of single thickness in the lateral parts of the end zones (5,6), formed from a rectangular piece of absorbent material comprising incisions in the end zones and subjected to a double folding around longitudinal lines connecting between them the incisions of the two end zones.

Abstract: Diaper comprising an absorbent pad between a practically waterproof outer sheet and a water-permeable inner sheet.The outer sheet (2) and the inner sheet (3) consist entirely of elastic materials, for example foams of plastics materials.Application: notably to diapers for infants.

Abstract: Improved adhesive-type securing device, notably for disposable diapers, and disposable diaper comprising such a securing device.Adhesive-type securing device, notably for disposable diapers comprising an impermeable thin flexible sheet carrying absorbent padding.Each of the diaper securing devices (7) comprises two tearable adhesive tabs (8, 9) fixed to the back part (4) of the diaper and capable of being fixed separately onto the thin sheet (1) of the front part of the diaper.Application: notably to disposable diapers for infants.
