Product Description Complete guide to all winder mechanical arrangements and control stategies; Practical and theoretical know-how for predicting and avoiding roll defects; Quantitative techniques for measuring and improving roll quality; Accompanying CD-ROM provides computer models for many winding situations -------------------------------------------------------------------------------- This new book, by two of the world's foremost experts, is the definitive guide to how winding machines work and how wound rolls are formed. It covers a wide array of machines in use across all web industries, including paper, film, foil, nonwovens, textiles, and more. It sets the standard for understanding and applying quality control in the field. Using hundreds of proven calculations, the book enables readers to understand and make the adjustments necessary to prevent roll defects and improve product quality. Dozens of examples and hands-on applications illustrate key techniques. Most of the book, especially the last section on measurement, is written in everyday language accessible to all responsible for machine operation and roll quality from engineers to shop floor managers. Review This extraordinary book does three things at the same time. First, it gives simple recipes for fixing problems and explains them with exceptional clarity and insight. Second, it gives the deep technical background as to why these recipes work. Third, through the use of case studies we can all recognise it shows how the theory and practice come together and make the recipes work. What sorts of problems does it help you solve? Telescoping, starring, tin-canning, bursts, crepe wrinkles, core collapse, high-speed vibrations, gauge bands. These are just some of the defects they discuss. A book written by a professor and a consultant could be a mixture of impenetrable academic prose and frothy consultant speak. But Good and Roisum make sure that you get the best of both worlds insightful science coupled with hard-nosed reality from the shop floor. The book is a delight to read There s a bonus. The book includes a CD with a powerful winding modeller. This means that you can put in your own winding parameters and see what s going on inside your own rolls taking into account taper, nip pressure, air entrainment and thermal/hygroscopic effects. In three words: buy this book! --Professor Steven Abbott, Research & Technical Director, MacDermid Autotype This book is a useful purchase for any engineer or technologist concerned with winding thin materials, particularly paper, film and similar products. It brings together the expertise of two world-leading experts in the field. Dr David Roisum is an inspiring teacher of winding principles and practice, and his seminars and courses are famous around the globe. I can almost imagine myself sitting in his class as I read the book! There are useful solutions to most winding problems, and the reasons why things are done are carefully explained. The sections of the book on machines and measurement especially show David s sympathy for the employees faced with turning out good rolls, of ever-changing products, on machines that may not be quite up to the job. His folksy approach and everyday analogies make this a very appealing book; although some of the technical and not-so-technical terms may mean little to those outside North America! Dr Keith Good has led the winding research at Oklahoma State University s Web Handling Research Centre for 20 years. During this time he has published many research papers, and these form the core of the section on modelling. Building on the basic calculation of stresses within a roll after winding, he has proposed and experimentally confirmed the additional effects of a contact roller, air entrainment, thermal and viscoelastic effects. He is acknowledged as the top academic expert on winding world-wide. As well as the published academic studies, he is familiar with the development work and pro
