Abstract: In a unit for making sections of padding for absorbent sanitary articles comprising a first rotary conveyor for feeding and forming a continuous succession of outer pads, comprising at least one layer, a second rotary conveyor for feeding and forming a continuous succession of inner pads comprising two layers, a third rotary conveyor for the pads defining a position for superposing the outer pads and the inner pads, there are compressing means for the two-layer inner pads upstream of the superposing position and second compressing means for the superposed pads downstream of the superposing position.

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.

Abstract: In a machine for making absorbent sanitary articles, such as nappies for babies or incontinence pads for adults, sanitary towels or the like, a plurality of operating stations are equipped with cutting and/or sealing devices for the materials of which the articles (2) consist; all or some of the operating stations each being equipped with at least one laser unit for performing the cutting and/or sealing operation; the laser units all being connected to the same laser source (60).

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.

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.

Abstract: Blanks used in the manufacture of nappies/diapers are folded on a machine comprising a first aspirating roller (5) by which single blanks (2) are advanced in succession toward a second aspirating roller (6) rotating counter and substantially tangential to the first roller (5) at a folding station (T).
