Abstract: A method for making absorbent sanitary articles whereby each absorbent article is provided with at least one pair of side tabs. The method includes the steps of feeding a single continuous web with a longitudinal axis towards at least one cutting station where the continuous web is divided, by a succession of cuts transverse to the longitudinal axis, into a first and a second series of side tabs, each of which has an asymmetrical shape and separately applying each rotated side tab of the first series and each side tab of the second series along a continuous strip of a material for making the absorbent articles, in such a way that each rotated tab of the first series is juxtaposed with a respective tab of the second series to define a respective pair of side tabs.
