System for Automatic Web Guiding for Roll-to-Roll Machine Working in a Start-Stop Mode

Abstract

Web guiding used in roll-to-roll material processing machinery is connected with a number of issues including the maintenance of the web tension, the precision of the lateral web displacement, the accuracy of transport positioning of the web, and the selection of web transport velocity. The article presents the precision of the lateral web displacement issue during the start-stop work mode of the web transport. A model of a system for automatic web guiding is shown. The requirements of the lateral web guiding for transporting material over rollers in a processing machine working in a start-stop mode are presented. The control system is discussed, particularly its hardware structure and behaviour. The obtained functionality of the control system enables its application in roll-to-roll material processing machines, working either in the start-stop mode or continuously.

Metrology and Measurement Systems

“…The end measurement result obtained after the uncertainty analysis may be used directly as an input signal for the terminal controlling the process. It may also be further analysed and processed on the PC [24]. Individual uncertainties of the measuring chain determine the total uncertainty of the air pressure measuring chain in low vacuum conditions.…”
