Abstract
An absorbent article, particularly a diaper, has a central absorbent unit (1) which is comprised of an elongated absorbent body (2) enclosed between a liquid-permeable inner casing sheet (3) which lies proximal to the wearer in use, and a liquid-impermeable, outer casing sheet (4) which lies distal from the wearer in use. The absorbent unit is provided along its longitudinal edges (9) with liquid-impermeable folds (6) which are upstanding from the inner casing sheet and which form side-leakage barriers. The article has a side-flap (18) on each side of the absorbent unit (1). The side-flaps (18), optionally with associated edge (21, 23), are produced in the form of rectangular strips (10) completely separated from the absorbent unit (1) and are thereafter jointed thereto. A longitudinally extending edge-part (13) of each strip (10) is suitably folded double and the backwardly fold part (19) is joined to the outer casing sheet (3a, 4b or 4) of the absorbent unit (1)along a curved fastening line (21). When the aper is to be used, the side-flaps (18) are pulled-out laterally, the length of this extension, and therewith the width of the resulting side-flaps (18), being dependent on the …
