Method for making absorbent sanitary articles

A method for making absorbent sanitary articles, comprising the steps of:

• feeding along a longitudinal direction of movement at least a first continuous web of material suitable for defining at least part of the main body of an absorbent sanitary article;
• feeding a pair of longitudinal strips;
• dividing each strip into a succession of trapezoidal pieces adjacent to each other and each having a long base and a short base, in such a way that the pieces of each strip can be divided alternately into first pieces having a first orientation and second pieces having a second orientation opposite to the first orientation;
• spacing the pieces of each strip from each other;
• rotating the first or second pieces of each strip by 180° in plane in such a way as to give the pieces of the first strip the first orientation and the pieces of the second strip the second orientation;
• wherein it comprises the following steps:
• applying each piece on a first face, in use, outer face, of the first web, in such a way that the long base of the piece protrudes laterally from the edge of the first web;
• folding the long base of each piece towards a second face, in use inner face, of the first web and fixing it to the second face.
