  • 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.

  • Patent number: 8790232
    Abstract: A machine for making absorbent items comprises a conveyor (9) for feeding a continuous strip (7) of absorbent items in a predetermined direction L, a cutting element (11) for cutting the strip into single absorbent items (2), a unit for feeding and applying to each stretch of the strip which will constitute a single absorbent item (2) a pair of fastening and closure elements (6) for the items; the unit (13) comprising a roller (18) for conveying a succession of pieces (15), intended to form the fastening elements (6), a separating device (22) consisting of a pair of rollers (20, 21) which are at a tangent to the conveyor roller (18) and equipped with suction seats (29, 30), able to slide parallel with their axes, for forming respective successions (32, 33) of pieces (15), which are spaced out in a direction T transversal to the direction L, by a stretch having a predetermined length, a roller (23) for forming pairs of pieces (15), which is at a tangent to both of the rollers (20, 21) and equipped with a first

  • Patent number: 8677930
    Abstract: Absorbent nappy/diaper pads composed of a first absorbent base material, and a second absorbent material consisting of superabsorbent polymer powders, are made by a unit (3) that comprises a conveyor (11) carrying the first absorbent material along a predetermined feed path (P), and a feed system (24) by which the superabsorbent polymer powders are released onto the feed path (P); the feed system (24) comprises a fixed duct (27) with an outlet (45) directed at the feed path (P), and a valve (34), positioned along an intermediate segment of the duct (27), by which the superabsorbent polymer powders are dispensed intermittently and controllably.
