- Reviews and explains material properties, roller mechanics, drives, tension control, nip control, guides, spreaders, winders, and more as used in calendaring, coating, laminating, printing and other web processes
- Addresses each topic from fundamentals through advanced concepts, including recent research findings and their practical application
- Explains how web handling systems work and why webs behave the way they do with detailed illustrations and easy-to-understand calculations (in both SI and American units)
- Provides the tools needed to troubleshoot and correct most web handling problems, including proven real-world best practices
- Emphasizes more profitable web processing through reducing waste from defects, downtime, and customer complaint
The Web Handling Handbook is a comprehensive guide to all technical aspects of handling or processing thin flexible materials written for anyone working with webs and web processes.
This engineering handbook is the first of its kind to comprehensively describe and discuss the wide range of technical aspects related to handling webs, which include paper, plastic films, foils, nonwovens, rubber, tissue, textiles and more. The book illustrates applied engineering principles and provides easy-to-understand calculations that inform how web systems are designed, maintained and operated. The handbook is meant to help readers to troubleshoot and correct defects such as wrinkles, bagginess, curl, and misshapen wound rolls. Written by foremost experts in web handling, this volume explains how to achieve the goal of moving the web optimally through web-to-roll manufacturing, as well as roll-to-roll and roll-to-sheet converting operations.
Mark A. Spaulding Editor-in-Chief Converting Quarterly – :
It’s been said that when “trying to be all things to all people, you can become nothing to nobody.” So at first glance, the thoroughness of The Web Handing Handbook can seem overwhelming, but it is just this comprehensive coverage of “all things web-handling” that makes it such a valuable, one-stop resource.
Having known Roisum, Walker and Jones and their respective work for anywhere from five to 25 years, I certainly wasn’t at all surprised by their extreme attention to detail combined with an easy-to-read, and sometimes conversational presentation of the technical information. Everyone from the novice to the seasoned manufacturing professional will find both basic explanations and applicable, hands-on solutions in the handbook’s hundreds of concise topics, whether you are running materials as traditional as newsprint paper or as sophisticated as flexible glass for printed electronics. And, while many in the R2R-processing field will admit that much can be attributed to web handling as an art, the authors’ work in clearly grounded in science from start to finish.
The Web Handling Handbook needs a home in every R2R-processing facility.

Shuzo Fuchigami Consultant, Precision Coating Technology Minnesota, USA – :
This is a very comprehensive handbook covering web handling processes and is tremendously helpful for those working in the converting industry, as well as researchers in academia working in web related processes. Those in industry, including process engineers, technicians, operators, maintenance professionals and equipment designers and its builders and those in academia, including instructors, students, and experimental technicians, will reap great benefits from this handbook. The book provides an understanding of the basics as well as detailed applications in web processes. The content is presented all the way from a materials basics chapter to coverage of process units associated with web process lines.
This handbook incorporates both the engineering science of the web handling process and the practical knowledge accumulated by years working in manufacturing operations, thus providing a uniquely valuable handbook. Excellent pictorial figures support the text and illustrate complicated web handling issues.
Chapter 12 More Web Handling Processing provides another unique feature of this handbook by discussing all web handling related issues, solutions to which are oftentimes critical to achieve quality manufacturing.
Some high technology industries must deal with extremely thin and wide films and unique pattern coated/printed webs and therefore have challenging issues in web handling. This handbook provides a good source of web handling fundamentals to understand and address these issues and provides solution strategies to achieve consistent manufacturing.
I would strongly recommend that those working in web processes have this handbook on hand.

Steve Lange, retired Research Fellow from the Procter & Gamble Company – :
In The Web Handling Handbook, authors Roisum, Walker, and Jones have created a comprehensive collection of their knowledge and experience gained from decades of consulting in manufacturing industries that convert thin, flexible materials into a wide array of everyday products comprised of metal foil, paper, plastic film, and textiles. Klassen also contributed extensively on Drives, and a dozen people from machine manufacturers and companies who apply web handling in their production facilities were enrolled as reviewers.
Given the diverse set of materials and products that employ web handling in their manufacture, it would seem impossible to supply a text that could be broadly useful but also have sufficient detail for specific applications, but these authors have succeeded by focusing on relevant engineering principles and fundamental science critical to web handling. These foundational concepts may be applied to any material/machine combination, and they present them in an accessible way, using plain language to explain their observations of common phenomena like wrinkles, web position errors and winding defects, and build on the basics with detailed recommendations for machine designers and process troubleshooters to avoid or solve issues that impact product quality and process reliability. Some equations are included, but the authors generally rely more on written description, graphics, and photos for explanation, with extensive references to commercial software, websites and academic research for those who wish to learn at even a deeper level.
In twelve chapters plus an extended set of appendices, the art and science of web handling is deconstructed, explained, and demonstrated with practical examples from the part and assembly level (materials, rollers, drives, nips, spreaders, and winders) to the key concepts needed for the control of webs: tensioning, lateral positioning, traction, and wrinkle/flatness. The differences in how various material classes and how their resulting properties affect the way webs behave are consistently covered in each chapter, and useful references to other chapters are provided, allowing the reader to enter the text at any point and navigate to their topics of interest. Several examples provide step-by-step methods, such as for solving wrinkle problems measuring nip parameters, and sizing drive motors.
Process engineers, machine designers and operators, especially those new to industry, will receive help from this essential reference by learning why webs do what they do in their machine, and how the machine’s state of maintenance, part design choices and configuration, and setpoints all play a role in web behavior, unlocking secrets to continuously improve operations by avoiding common errors or correcting them in an efficient way.
