Abstract: A rotary welding device which includes a rotary part rotating about its axis of rotation, one or more supporting elements for supporting a continuous strip, specifically a strip of nappies, supported by the rotary part, and a plurality of welding units, mounted on the rotary part, for welding the continuous strip; each welding unit is configured to pass from a non-operating position to an operating position and vice versa; each welding unit includes a respective welding tip and a respective anvil element which is movable relative to the welding tip; each welding unit includes respective first movement means configured to drive the anvil element in rotation relative to the welding tip from an initial position, where the anvil element is angularly spaced from the welding tip, to a final position, where the surface of the welding tip and the surface of the anvil element are parallel and aligned with each other along the same axis, and vice versa.

Abstract: A method for making absorbent sanitary articles, each comprising a first discrete element and a second discrete element, comprises: feeding a succession of first discrete elements along a first feed path; feeding a succession of second discrete elements along a second feed path; applying each first discrete element of the succession of first discrete elements on a support web having a longitudinal axis and movable in a feed direction along a third feed path, the first discrete elements being applied on the support web at a first applicator station; applying each second discrete element of the succession of second discrete elements on the support web at a second applicator station located downstream of the first applicator station in the feed direction of the support web; the method comprises adjusting a length of the third feed path between the first applicator station and the second applicator station, so that each second discrete element is applied on the support web at a predefined position relative to a respective first discrete element.

Abstract: A method for processing a discrete segment of material for absorbent articles comprises picking up the segment from a first succession of segments disposed at a first spacing from each other; releasing the segment to define a second succession of segments disposed at a second spacing from each other; rotating the segment carried out between the step of picking up and the step of releasing and which involves disposing the segment from a first configuration, corresponding to the configuration of the segment of the first succession, to a second configuration, rotated relative to the first configuration and corresponding to the configuration of the segment of the second succession; between the step of picking up and the step of releasing, accelerating the segment and decelerating the segment; the rotating the segment being carried out simultaneously with at least one between the accelerating and the decelerating.

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.
