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).
