Abstract
Abstract A methof of manufacturing a two-wing one-piece dress-shielding element with two wings each composed of an absorbent layer adapted to lie against the body of a user and a moisture-impermeable layer adapted to lie against a dress, includes the steps of continuously supplying a web of material for forming at least one of the layers of the dress-shielding element, providing a plurality of working stations for performing a plurality of working steps for manufacturing the dress-shielding element, and displacing the web between the working stations so as to perform the working steps, whereby the web serves as transporting means for the dress-shielding elements to be manufactured from the web. A dress-shielding element includes a body part composed of a web material and having two wing portions connected with one another in a transition region, and a mass of superimposed web material provided in the transition region and deformed so as to form a common concave edge line for both wings of the dress-shielding element.
