Abstract: In an absorbent disposable article, such as in particular a diaper, in which an absorbent body is covered on one side by a liquid-impermeable protective sheet and on the opposite side by a porous layer, certain edge areas of the porous cover layer should be provided with a liquid-impermeable protective layer.This protective layer is formed as a prefabricated impervious sheet and possesses, before being placed on cover layer, on one side a smooth and the other side an extremely coarse surface. The impervious sheet serving as the protective layer penetrates essentially exclusively with its coarse surface areas inside the cover layer. Through the smooth side of this impervious sheet, an absolute imperviousness is assured. Because of the physical bond, which forms between the impervious sheet and the cover layer, the impervious sheet can be formed extremely thin, i.e., a minimum amount of material is sufficient for the impervious sheet.

The first strip is then brought into a condition of extending parallel to a second strip produced in the same manner, with an adhesive between the two strips. The two strips are then passed through a pair of rollers which press the assembly together, thereby forming an elongate panel configuration.

Abstract: To make diapers having elasticized regions, unstretched segments of elastic ribbon are deposited on a first rotating roll which has vacuum holes in its periphery for attracting the body of a segment and a mechanical element for temporarily securing one end. The first roll rotates segments successively to a place adjacent a second roll which has a larger radius and, hence, higher peripheral velocity than the first roll. The second roll has grippers spaced apart by an amount substantially equal to the desired stretched length of the segments. The leading end of each segment on the first roll is engaged by a gripper on the second higher speed roll so the segment stretches after which a lifter on the first roll releases the trailing end for it to be engaged by a gripper to hold the stretched segment on the second roll. Quick setting glue is applied to the stretched segments and the top porous sheet material comprising the diaper is run in contact with the segments to pick them up.
