Abstract
A method for making sanitary articles, includes: feeding along a longitudinal direction of movement a first web of material defining a main body of the article; feeding a pair of longitudinal strips; dividing each strip into a succession of trapezoidal pieces adjacent each other and each having a long base and a short base so 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 to give the pieces of the first strip the first orientation and the pieces of the second strip the second orientation; applying each piece on a first face so the long base protrudes laterally from the edge of the first web.
