Summary

Measuring internal roll pressures from the winding process is usually done after the winding is complete. This approach is unable to see the dynamic effects within a winding roll, such as slippage and roll rotation. In this paper, Wireless Monitoring of Internal Wound Roll Pressures, Timothy J. Walker discusses how he used Tekscan’s I-Scan™ Pressure Mapping System to measure the dynamic roll pressure during the winding process. With the I-Scan system, he was able to map the pressure distribution of the nip roller to see the contact, pressure losses from roller imperfections, and pressure variations that were not able to seen using other methods.
