The invention concerns a process for the permanent attachment or joining of threadlike or small ribbonlike elastic elements to a flat substrate by means of an adhesive that is characterized by the fact that one disposes, or fixes, in the desired position, one or several threadlike or small ribbonlike elastic elements on the flat substrate, or guides them in the desired position at a distance of about 1 to cm from the flat substrate, and covers these elastic elements, and some portion of the adjacent region of the substrate with a sprayed-on melt adhesive, and in the case of guiding at a distance, brings the threadlike or small ribbonlike elements into contact together with the fleece course. The invention further concersn application of the process for producing frilled section of foil course or film sheet with stretchable threadlike or small ribbonlike elements located in the respective edge region between a foil course or film and a covering layer, an absorbent layer disposed therebetween, and a covering section of fleece.

A process for the permanent joining of stretchable threadlike or small ribbonlike elements to a flat substrate by means of an adhesive, characterized by the fact that, prior to application of the adhesive, one or several threadlike or small ribbonlike elastic elements (4) are disposed or fixed in the desired position at some distance from, the flat substrate (2), and that afterwards these threadlike or small ribbonlike elements (4) as well as the adjoining area of the substrate (2) are covered with a sprayable melt adhesive (6). A process according to claim 1 for producing frilled sections of film, with stretchable threadlike or small ribbonlike elements located in the respective edge area between a film and a covering layer, an absorbent inlay disposed therebetween, and a layer of felt covering these latter, further characterized by the additional steps of: (a) placing or fixing on the film (22) serving as a substrate, in the respective, later-frilled edge areas, either on this film (i) in the frilled or pleated condition one or several not, or slightly, stretched, (ii) in the flatly laid condition, one or several threadlike or small ribbonlike elements (24, 24′), (b) intermittently spraying with the melt adhesive the respective threadlike or small ribbonlike elements, as well as their adjoining areas, and simultaneously the area (27) lying between the threadlike or small ribbonlike elements, (c) next, placing on the area (27) sprayed with melt adhesive between the threadlike or small ribbonlike elements a course made of an absorbent padding material (28), (d) placing onto the film (22) and the course made of absorbent padding material (28) a fleece course (29), in a manner such that this latter covers the absorbent padding material (28) and also lies over the threadlike or small ribbonlike elements (24, 24′) sprayed with the melt adhesive, (e) pressing the fleece course (29), at least in the area of the threadlike or small ribbonlike elements, together with these latter and, (f) cutting off the thusly obtained bonded material in sections transversely to the course direction.
