Absorbent pads for personal sanitary items are made by a device that comprises a set of pick-up heads (2) moving along a feed path (P), a first application unit (5) and a second application unit (6) by which a respective first portion (4a) and second portion (4b) of an absorbent pad are placed on the pick-up head (T), and a motion-inducing mechanism, coupled to the pick-up head (2), which is designed to bring about a relative displacement between the first portion (4a) and the second portion (4b), so that when the second portion (4b) is placed over the first portion (4a), the one will be covered by the other only in part. A method of making absorbent pads using the device in question includes the steps of preparing a first portion (4a) and a second portion (4b) of an absorbent pad, then placing the second portion (4b) over the first portion (4a) in such a way that the first portion (4a) is covered only in part by the second portion (4b).

L'invention porte sur des tampons absorbants pour articles d'hygiène personnelle fabriqués par un dispositif comprenant un ensemble de têtes de capture (2) se déplaçant sur un trajet d'alimentation (P), une première unité d'application (5) et une seconde unité d'application (6) au moyen desquelles on place respectivement une première partie (4a) et une seconde partie (4b) d'un tampon absorbant sur la tête de capture (T), et un mécanisme induisant un mouvement, couplé à la tête de capture (2), conçu pour exécuter un déplacement relatif entre la première partie (4a) et la seconde partie (4b), de telle sorte que lorsque la seconde partie (4b) est placée sur la première partie (4a), l'une ne sera recouverte qu'en partie par l'autre. Le procédé de fabrication de tampon absorbant à l'aide du dispositif en question comprend les étapes de préparation d'une première partie (4a) et d'une seconde partie (4b) d'un tampon absorbant, puis de mise en place de la seconde partie (4b) sur la première partie (4a) de telle sorte que la première partie (4a) n'est recouverte qu'en partie par la seconde partie (4b).
