Fremgangsmate og anordning for inspisering av komposittgjenstand med forste og andre felt i minst delvis motsatt overlappende inngrep med hverandre.

摘要

A system and process for inspecting an underlying edge of a composite article, such as a disposable absorbent article. The article has first and second panels in at least partially opposed, overlapping engagement with each other. The process and system determine whether the panels of the article are present and/or properly positioned. Also disclosed is a process and system for detecting whether one or more components are present and/or properly positioned in the composite article by use of infrared radiation. Also disclosed is a process and system for defining a window in an image of the article, scanning the defined window to determine a position of the edge and redefining the window in the event that the edge is not located within the defined window during scanning of the defined window.
