Abstract: An apparatus for forming an absorbent pad for an absorbent sanitary article having a zone free of absorbent material to define a channel of the pad includes a forming drum, a first feed system for feeding a first web, a second feed system for feeding a second web, a spreader for spreading the absorbent material on the drum; a joining system for joining the first and second webs to define the channels. A first dispenser forms on the first web a layer of first adhesive substance according to a spreading pattern having zones free of the first adhesive substance corresponding to the channels. A second dispenser dispenses a second adhesive substance, whose adhesive force is greater than an adhesive force of the first adhesive substance, on the second web according to a pattern having a layer placed at a zone free of the first adhesive substance.

Abstract: A rotary device for welding a continuous web comprises a rotary unit rotating about a respective axis and welding units for welding the web mounted, angularly spaced, on the rotary unit. A movement device varies a radial position of the welding units. First and second supporting elements supporting the web are disposed, respectively, upstream and downstream of respective ones of the welding units, to keep the web tensioned when the respective welding unit is at an operating position. The first and second supporting elements are supported by a load-bearing structure connected to the welding units in such a way that a radial movement of the welding units corresponds to a movement of the first and second supporting elements towards and away from the axis.

Abstract: A device for applying pieces to absorbent articles includes a supporting shaft rotating an axis; anvils rotating about the axis; a cutting unit operating with an anvil contact surface defining a cutting station for cutting a web into pieces; pads, each having a retaining surface for a piece, are moved about the axis for conveying a piece from the cutting station to a releasing station for release onto a substrate. Each pad rotates for varying the orientation from the cutting station, where the larger side of the pad is parallel to feed of the web, to the releasing station, where the larger side of the pad is transversal to the feed of the receiving substrate, and vice versa. Each pad translates parallel to the pad axis, away from and towards the shaft axis. Each pad has an oscillating movement about its own axis.

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.
