This unique manual presents an excellent database of defects found in the winding, web handling, papermaking, calendering, extrusion coating, laminating and slitting processes. It provides a means for web producers, converters, and printers to communicate defect problems through a common language, thus facilitating more meaningful statistical treatment of defects, allowing the user to bring the process under control. The book uses photographs and drawings to demonstrate a litany of roll and web defects.

This revised and expanded edition includes new information on wrinkling of webs, as well as on defects found in non-paper products such as films, nonwovens, and laminations. It follows a cause and effect logic so you can look for common problems in a process and uncover the underlying reasons for the defects. Recommended.

From the Preface: “...Many times the quaint and colloquial terms used to identify roll and web defects vary from one industry to the next which makes identification difficult. This book cross references the different synonyms for each defect. The index then becomes a very useful tool to reference the common defect name to the synonyms. The book lists the most common causes and remedies for these defects...”

Target Audience: Quality assurance and process control personnel; plant management; production supervisers; and operators of winders, slitters, printing presses, and other converting machinery.
