Abstract: A feeding unit to feed a component in an automatic manufacturing machine; has: at least one holding head designed to receive and hold the component; a closed curved guide arranged in a fixed position along an application path; an equipment supporting the holding head and provided with at least one slide coupled to the guide by a plurality of wheels; a linear electric motor, and a movable slider electro-magnetically coupled to the stator and is rigidly connected to the slide. The guide has, on the surface in contact with the wheels, a first transverse profile having a concavity or a convexity; the wheels have, on the surface in contact with the guide, a second transverse profile, which has a convexity or a concavity, and generates, with the first profile, a shape coupling between the guide and the wheels, which forbids a transverse movement of the slide relative to the guide.

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

Abstract: In a method for making absorbent sanitary articles, each absorbent article includes a pair of side tabs fed from a single continuous tape divided by oblique cuts into first and second series of side tabs oriented in opposite directions. The side tabs of the first and second series are then fed along a first path and along a second path, respectively and are first rotated by 180° and then combined and transferred separately along a third, common path along which each tab of the first series has a respective tab of the second series placed alongside it to form a pair of side tabs. At least one of the side tabs of each pair is moved sideways such that each pair of side tabs is applied to a continuous web of material at a predetermined spacing.
