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: An apparatus and method for producing an absorbent sanitary article including a forming surface at least partially permeable to air configured to move along a moving direction between first, second, and third successive forming positions. The apparatus includes a first, second, and third supply ducts for delivering loose absorbent material onto the forming surface at the first, second, and third forming positions, respectively. The apparatus further includes a first suction chamber opposite to the first supply duct with respect to the forming surface and arranged at the first forming position, a second suction chamber opposite to the second supply duct and arranged at the second forming position, and a third suction chamber opposite to the third supply duct at the third forming position. The first, second, and third suction chambers are open on the forming surface and configured to exert a suction through the forming surface.

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.
