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 folding apparatus for a continuous web for production of absorbent hygiene articles and intended to be folded into a “V” or “U” shape in first and second longitudinal portions along a folding line parallel to a feeding line. A folding section includes a contact unit extending along the feeding line and defining the folding line. First and second guides are positioned on opposite sides of the contact unit and respectively have first and second sliding surfaces. The first and second sliding surfaces extend in a helical fashion along the feeding line, each having a respective infeed section, where the web is not folded, and a respective outfeed section, positioned downstream of the respective infeed section according to a web feeding direction, where the web is folded in two and has the first portion and the second portion set at an angle to each other.

Abstract: A feeding unit to feed a component in an automatic manufacturing machine, which has at least one holding head designed to receive and hold the component; a conveyor to cyclically move the holding head along an application path; and a rotation station arranged along the feeding path and in which the holding head rotates relative to the equipment and around a rotation axis to vary the orientation of the component. The conveyor has a closed curve guide arranged in a fixed position along the application path; and an equipment supporting the holding head and provided with at least one slide coupled to the guide so as to freely slide along the guide. An actuation system controls rotation of the holding head around the first rotation axis and has a cam and a cam follower roller, which can be coupled to the cam and mechanically connected to the holding head.

Abstract: A unit for applying first and second tabs, obtained from first and second webs, to a chassis web includes an applicator drum rotatable about an axis and including a main body. A plurality of carriers is movable between a lowered position close to the axis and a raised position away from the axis, each including a suction portion. A first carrier first suction and non-suction portions aligned along the axis. A second carrier includes second suction and non-suction portions aligned along the axis. The first suction portions alternate with the second non-suction portions and the first non-suction portions alternate with the second suction portions. A first system holds the first web on the applicator drum upstream of a cutting device. A second system holds the second web on the drum upstream of the cutting device.

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.
