Abstract: A method for forming an absorbent pad including a first layer, a second layer and an absorbent material interposed between the first and the second layer and arranged according to a spreading pattern M1 having at least one channel which is free of absorbent material, includes a step of feeding a first web, intended to form the first layer of the pad; a step of feeding a second web, intended to form the second layer of the pad; a step of spreading the absorbent material on the first web according to the spreading pattern M1; a step of joining the first and second webs, a step of removing any absorbent material that may be present in the channel.

Abstract: A feeding unit for feeding a component of a hygiene absorbent article; the feeding unit has: at least one sucking-holding head, which is designed to receive and hold the component; a conveyor to cyclically move the holding head along an annular application path; an input station in which the holding head receives a corresponding component which is connected—without gaps—to a continuous web; a cutting station provided with a cutting device, which cuts the continuous web crosswise; and an output station in which the holding head releases the component; the conveyor has: an annular guide; a slide which supports the holding head and is coupled to the guide so as to freely slide along the guide itself; and a linear electric motor, which has a stator, which is arranged in a fixed position along the guide and a mobile slider which is electro-magnetically coupled to the stator so as to receive, from the stator, a driving force and is rigidly connected to the slide.

Abstract: A process for forming an absorbent sanitary article includes feeding a first web including first and second stretches each having front and rear end portions; feeding a second web for forming a first side panel of the article; feeding a third web for forming a second side panel of the article; cutting the second web into a succession of first and second pieces defining the first side panel of the article; cutting the third web in a succession of third and fourth pieces, defining the second side panel of the article; applying the first through fourth pieces to the first web; the first and second stretches being provided in the first web so each first stretch has the rear end portion upstream of the front end portion in a feed direction and each second stretch has the front end portion upstream of the rear end portion.

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: A unit for making absorbent pads for nappies including a forming drum by which the absorbent pad is formed and in turn including on its peripheral surface one or more suction recesses; at least one hood for feeding the absorbent material and peripherally facing at least part of the peripheral surface of the drum; and a duct which leads to the hood and which can intermittently feed predetermined charges of a superabsorbent material; the feeding duct is configured in such a way that the flow of superabsorbent material fed into the hood expands until reaching an extent corresponding to the longitudinal extension of the at least one discrete layer of the absorbent pad.
