A unit for forming absorbent sanitary articles comprises a drum (2) rotatable about its axis of rotation (A) and having a circumferential peripheral surface (2a) movable along a feed direction (B), first feeding means (3) for feeding a succession of pairs of panels (102) of material facing the circumferential peripheral surface (2a) and configured to position each pair in such a way that the respective two panels (102) are facing each other and transversely aligned with the feed direction (B) and second feeding means (4) for feeding a continuous web (101 a) of material suitable for defining at least part of the main body (101 ) of an absorbent sanitary article (100), and configured to position the web (101 a) on the circumferential peripheral surface (2a) of the drum (2) in such a way that each panel (102) projects partly sideways from the web (101 a). The unit comprises an ultrasonic sealing station (7) located along the circumferential peripheral surface (2a) of the drum (2), in a zone located operatively downstream of the second feeding means (4), and configured to attach each panel (102) of the pair to the web (101 a) at at least one plurality of sealing points (8) arranged in succession along the feed direction (B). |
