Thickness measurement sensor for laminated layer on belt involves distance measurements along width of belt and uses Kalman filter to determine thickness of laminate

摘要

The distance between the sensor and the upper surface of the belt (5) is measured by a sensor (8) at regular points along the width of the belt, perpendicular to its direction of movement. The thickness of the laminate layer is calculated using the measured distance value and a switching Kalman filter. An independent claim is included for a control variable regulation method for a lamination process.
