Abstract: Control processes control cross direction alignment of elements being assembled as work pieces on a manufacturing line fabricating preferably absorbent article products on a continuous substrate web. The method defines a manufacturing line path traversed by the work pieces, defines a reference path along the manufacturing path, and establishes the elements on the work pieces. A camera is mounted along the manufacturing line. An image window of the camera is referenced to the reference path. The camera captures full digitized visual images of work pieces. The camera is part of a vision imaging inspection and control system which inspects and evaluates images of the work pieces, including the cross-direction positions of the elements on the work pieces, against established acceptable positions relative to the reference path. When an element is out of alignment, the control system can display visual cues identifying the elements that are inconsistent with acceptable ranges.

Abstract: Apparatus and method using vision imaging for combined short-term and long-term monitoring and control of a manufacturing operation which produces absorbent articles for absorbing body fluids. The system collects discrete real-time visual images at a rate of at least 50-400 images per minute, up to at least 1200 images per minute, provides an ongoing display of a pattern of such images, and upon occurrence of a triggering event, continues the visual display of the images while sending information representing a limited number set of real-time visual images to a memory storage system which receives and permanently stores the information, for future retrieval. The data is preferably received in a temporary memory device, and written from there to a second permanent memory device.

Abstract: Controlling processes comprising detecting and measuring a parameter, for example presence and location of an element of a good, with at least two determinations as representations of the target parameter, transmitting signals to the computer, and processing the signals to compare the parameter to acceptable conditions. The detection can include three or more replications, optionally each for at least two parameters, optionally using at least two different methods to analyze the signals. The invention contemplates detecting and analyzing the target parameters using two or more analytical tools within the respective image to detect a given component of the product, namely two or more measurements of the parameter on a single visual image.
