Normal Wave Propagation Velocity in a Static Web.

Abstract

Web tension measurement and control has been a major problem in web processes since the first conceptual phases of web handling. The systems currently in use require contact with the web and generally produce an average tension measurement across the span of the web. This study investigated the variance of normal wave propagation velocity with respect to variation of tension. The theory is that the normal wave propagation velocity will increase with increasing web tension and decrease with decreasing tension. Experiments were performed on a static web and incorporated both standing and propagating wave techniques. The goal of this research was to provide information for the development of a device to measure web tension without contacting the web surface and which would provide information as to the tension variance across the span of the web.
