Abstract: The present disclosure relates to systems and methods for making adjustments to the web converting machinery based upon the measured web caliper. Generally the web caliper is measured without contacting the web and in real time while the web is being conveyed at high rates of speed. The web caliper measuring system may be employed in the web converting system to improve web caliper control and improve winding. The web caliper measurement may be fed back to a calendering system to improve the caliper of web fed into a winding system, or the caliper may be fed forward to the web winding system to improve web tension and winding performance.

Abstract: A web winding and measuring system is provided. The system includes a rotatably-mounted spool onto which a web of material is wound to form a roll. The system additionally includes a light-emitting device configured to illuminate the roll by light, providing a line on a cylindrical surface of the roll in a cross-machine direction, a light-receiving device configured to detect the line and generate measurement data from the detected line, and a computing device communicatively coupled to the light-receiving device and configured to receive the measurement data and calculate a diameter of the roll.
