Materials shortages, inflated raw material and production costs have required vinyl processors to optimize their product yield per pound of raw materials without sacrificing product quality. In addition, to stay competitive in today's markets, companies have been forced to improve productivity. This paper describes a measurement and control system for a vinyl calender. This system uses the distributed microcomputer architecture. The principle objectives of this digital computer system are: 1. Control weight per unit area at the windup to fixed or optimal targets. 2. Control the cross direction zones to maintain a desired profile. 3. Provide a simple, easy‐to‐use operator interface to facilitate code or product setup, to provide process status, and to maximize control utilization by the operator. 4. Provide management information in graphic and alphanumeric form. This paper also describes scanner and sensor used for measuring the weight per unit area, total and three‐zone weight control, target adaptive control, preset control, operator interface via an interactive video, and management inormation. It also presents actual plant results obtained under manual and computer control.
