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.
