ABSTRACT:
A carrier strip or filament of cold drawable material is utilized to transport discrete lengths of elastic ribbon within a manufacturing apparatus. The elastic ribbons are extruded onto the carrier strip or around the filament and adhere thereto. The carrier strip and elastic ribbon are jointly stretched a predetermined amount. The stretched carrier strip and stretched elastic ribbon are bonded to a component of a final product, as, for example, the backing sheet of a disposable diaper, wherein the elastic ribbons are employed to elasticize the leg areas. The carrier strips greatly facilitate machine handling relatively short lengths of stretched elastic ribbons without waste. The carrier strips may be transversely guided along a predetermined path to follow the hourglass contour of the margins of a diaper having form fitting legs.
