  • Publication number: 20190076300
    Abstract: A method for making absorbent sanitary articles whereby each absorbent article is provided with at least one pair of side tabs. The method includes the steps of feeding a single continuous web with a longitudinal axis towards at least one cutting station where the continuous web is divided, by a succession of cuts transverse to the longitudinal axis, into a first and a second series of side tabs, each of which has an asymmetrical shape and separately applying each rotated side tab of the first series and each side tab of the second series along a continuous strip of a material for making the absorbent articles, in such a way that each rotated tab of the first series is juxtaposed with a respective tab of the second series to define a respective pair of side tabs.

  • Publication number: 20190060134
    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.

  • Publication number: 20190060133
    Abstract: The unit for feeding lateral flaps of a hygiene absorbent article having: an input conveyor of a first continuous strip; a cutting assembly provided with a receiving drum, of the first suction-pick up heads that hold the lateral flaps and which are mounted to as to be radially movable on the receiving drum, and at least one blade which cyclically cuts the first strip crosswise; a spacer assembly having a pair of spacer drums provided with second suction-pick up heads that receive the lateral flaps of the receiving drum; and an actuator system, which cyclically moves each first suction-pick up head radially between a radial pick-up position and a radial release position, in the area of an output station.

  • Publication number: 20180290855
    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.

  • Patent number: 9776824
    Abstract: A method and unit for folding light incontinence pads having a substantially rectangular shape elongate according to a longitudinal axis and comprising a central absorbent pad and an outer edge, according to which a first end portion of the incontinence pad is folded on a central portion of the incontinence pad about a first fold line transversal to the longitudinal axis, a second end portion of the incontinence pad is folded on the first end portion about a second fold line transversal to the longitudinal axis, and elasticated segments of the edge located between the first and second fold lines are folded on the central portion; the step of folding the elasticated segments of the edge being between a first sub-step of partly folding the first end portion and a second sub-step of completely folding the first end portion on the central portion.

  • Patent number: 9733624
    Abstract: A method for corrective action on the operation of a line for the production of absorbent sanitary articles, comprises capturing at least one image of each article being fed out of the line; using the image to define first parameters indicating the positioning and/or assembly and/or shape of at least one respective component; detecting a production defect if at least one of the first parameters is outside a respective acceptability range; identifying second, line operating parameters which are used to indicate if the first parameter is outside the respective acceptability range; comparing the line operating parameters with respective third, reference parameters indicating optimum line operation; using the comparison to derive a map of abnormal operating parameters; checking if each combination of abnormal operating parameters indicates a respective cause of malfunction of the line; defining a respective corrective action.

  • Patent number: 9475250
    Abstract: A method including folding incontinence pads which have a substantially rectangular shape, elongate according to a longitudinal axis, and including a central absorbent pad and a perimetric edge. The method includes folding parts of the edge onto a central portion of the absorbent pad, folding a first end portion of the incontinence pad about a first fold line onto the central portion and a subsequent step of folding, about a second fold line a second end portion onto the first portion. The fold lines which are transversal to the longitudinal axis and define the central portion are spaced by a stretch which is greater than or equal to the longitudinal dimension of the first end portion. The folding step is preceded by a step of folding down inwards onto the central portion segments of the edge which lie between the first and second fold lines, and a step of retaining said segments of the edge on the central portion.
