摘要： In a method for making absorbent sanitary articles, each absorbent article includes a pair of side tabs fed from a single continuous tape divided by oblique cuts into first and second series of side tabs oriented in opposite directions. The side tabs of the first and second series are then fed along a first path and along a second path, respectively and are first rotated by 180° and then combined and transferred separately along a third, common path along which each tab of the first series has a respective tab of the second series placed alongside it to form a pair of side tabs. At least one of the side tabs of each pair is moved sideways such that each pair of side tabs is applied to a continuous web of material at a predetermined spacing.

摘要： 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.
