<p>A ruffling slide for making articles with stretchable portions is disclosed. Said slide includes a tubular sleeve (1) for containing at least one resiliently stretchable wire-like element (5); connecting portions (6) transversely provided on the sleeve and spaced apart in such a way that they define tubular ruffling sections (7), said connecting portions also forming narrowed portions (8) for locally clamping said wire-like element; and at least one wire-like element (5) inserted into the sleeve and clamped at the narrowed portions in such a way that it extends freely through each tubular section and is movable therein between two positions, i.e. an inoperative position (51) and an operative position in which said element is shorter than the section in question, whereby it may subsequently impart a ruffle thereto in a direction substantially perpendicular to the general direction of the sleeve. The slide is useful in nappies and diapers.</p> |
