Critical web handling problems that can be related to improper tension control include wrinkle, slack, breakage, lateral movement, and poor roll quality. This text — the only reference currently available devoted entirely to tension control — provides a thorough study of the longitudinal dynamics and tension control of web handling systems. It presents analyses of primitive elements and subsystems, non-ideal effects, and dancers; it also discusses analytical and experimental analyses of various multi-span systems.

From the Preface: “...In this book...the analysis will start with the primitive elements, which will then lead into the analysis and design of the web-handling systems. In this way, readers with different backgrounds and familiarity with web-handling system configurations and web materials can apply the information from the book to their own cases more easily. The manuscript covers tension control issues and fundmental behaviors in web-handling behaviors like web traction and initial mechanical properties of the web. Then open-loop mathematical models for `primitive' elements and subsystems in multi-span web transport systems explain non-ideal effects on tension variation and interactions between adjacent web spans...”

Target Audience: Engineers, researchers, maintenance, and manufacturing personnel, as well as students and others interested in tension control.
