Abstract

A method for inspecting disposable absorbent articles, the method comprising: providing a controller comprising an inspection algorithm with a convolutional neural network; providing a sensor, preferably selected from the group consisting of an optical sensor, thermal sensor, and combinations thereof; the sensor being in data communication with the controller; providing a reference database, wherein the reference database comprises a plurality of pre-processed images of disposable absorbent articles and/or components thereof that have been labeled with one or more of: a feature or element of the article and/or component thereof; a non-acceptable defect within a feature or element of the article and/or component thereof; an acceptable defect within a feature or element of the article and/or component thereof; an acceptable faultless feature or element of the article and/or component thereof; and combinations thereof; and the method comprising the steps of: training the convolutional neural network preferably through a plurality of iterations or epochs; optionally validating the training, wherein the training step is repeated until a mean average precision score (MAP) of at least 0.9 is attained according to the formula (I) where Q is the number of queries; advancing one or more substrates through a converting process along a machine direction to form an array of absorbent articles; creating a plurality of images of said array of absorbent articles with the sensor; transmitting the images from the sensor to the controller; determining at least one of the properties for the labeled component with the inspection algorithm; cutting the substrate into discrete articles; and based on the determination of the least one of the properties for the labeled component, executing a control action, wherein the control action is selected from the group of automatic rejection of one or more articles, automatic machine-setting adjustment, a warning signal for machine maintenance scheduling, and a machine stop command.

Abstract

An absorbent article comprising: a chassis comprising a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core positioned between said topsheet and backsheet, and comprising a longitudinal axis (y) extending along a length of said chassis and a transverse axis being substantially perpendicular to the longitudinal axis and extending along a width of said chassis, wherein said length extends along the longest dimension of said chassis; and at least one elastically elongatable panel joined to the chassis, wherein the elastically elongatable panel comprises: a. at least one cover layer; and b. an elastomeric film attached to the cover layer, wherein said least one cover layer and elastomeric film are joined by mechanical bonding at a plurality of discrete bonding elements, and wherein each said panel comprises a plurality of wrinkles having peaks and troughs formed on at least one of said cover layer, and wherein the said panel comprises a plurality of openings extending through the film and/or the cover layer(s) and wherein said openings are positioned outboard and/or inboard of said discrete bonding elements so that said openings and said bonding elements do not substantially coincide.
