Abstract: A method and apparatus for depositing discrete elements on a support element. The discrete elements may be separated from each other or joined to form a continuous web. The discrete elements are fed into a pick-up station defined at a rotor which includes circumferentially adjacent pick-up members. Each discrete element is associated with a respective pick-up member having a first orientation with respect to a respective second axis of rotation. Each pick-up member is moved along the rotation direction towards a release position downstream with an at least partially accelerated or decelerated motion. Each pick-up member is rotated about the respective second axis of rotation until it takes, at the release position, a second orientation. Each discrete element is released on a support element at the release position. Each pick-up member is subsequently moved towards the pick-up station with an at least partially decelerated or accelerated motion.

Abstract: A method for making an absorbent sanitary article (10) comprises: applying a plurality of adhesive portions (16, 17) on a backsheet web (114), each adhesive portion (16, 17) comprising a removable covering sheet (4) and a glue layer (5) overlaid on said covering sheet (4); subsequently, forming a multilayer web (30) of absorbent sanitary article (10) comprising said backsheet web (114), a topsheet web (112), a plurality of absorbent cores (18) interposed between said topsheet web (112) and said backsheet web (114), and said plurality of adhesive portions (16, 17) applied to said backsheet web (114), wherein said adhesive portions (16, 17) are arranged on said backsheet web (114) on opposite sides with respect to said plurality of absorbent cores (18).

Abstract: A method for forming and folding an absorbent sanitary article includes the steps of preparing a continuous, multilayer web and feeding it in a feed direction, applying a succession of absorbent pads, spaced from each other, on the continuous, multilayer web, folding the absorbent pads on the continuous multilayer web, temporarily fastening the folded absorbent pads to the continuous, multilayer web, making a succession of lines of weakness in the continuous, multilayer web between consecutive absorbent articles, folding a first flap of each absorbent article towards the corresponding absorbent pad, folding a second flap of each absorbent article towards the corresponding absorbent pad; folding the first flap or the second flap includes tearing the continuous, multilayer web at the lines of weakness, thereby separating the absorbent articles.
