In Tetra Pak lamination process, extrusion coating on the board is applied at different stations of the process line. Polymer missing on the edges or folding is a failure developing from the instability in the process. This instability causes reduction in the neck in during ramp-up, increase in the neck in during ramp-down and instability of the edge during stable (constant) speed. To avoid these failure modes, the deckles are kept at positions such that the extra (wider than the web-width) polymer is applied on the board. This project seeks to design a system for the measurement of the width of the extra polymer (trim on edges) in the extrusion coating (lamination) processes and develop fully configurable software for robust estimation of the trim width; and deploy the system in the Tetra Pak Arabia factory. This development limits this waste material produced during production, the extra trim polymer will be kept to a minimum while still limiting the polymer missing rate.
