<p>A method for applying trapezoidal elastic wings to the chassis of a diaper includes the steps of: providing a ribbon, from which alternating adjacent trapezoidal panels are obtained, each having a smaller base and a larger base that are alternated on each side of the ribbon; applying a tape to the panels ribbon, at the smaller base of each panel, providing an elastic wing constituted by the trapezoidal panel provided with the respective tape; applying the wings to a first side of a support material ribbon, by means of a single functional unit; diverting the support material ribbon and feeding again the support material ribbon to the single functional unit in order to apply the wings to the other side of the support material ribbon by means of the single functional unit. The apparatus is characterized by the single functional unit, constituted by a shaping device and a pair of wing applicators; the single functional unit receives the support material ribbon and the elastic material ribbon on which the elastic wings are provided; the single functional unit applies the elastic wing to the first side of the support material, which is diverted by an axial diversion means and fed again to the single functional unit, which applies the second wing to the other side of the support material ribbon, aligned with the first elastic wing.</p> |
