When web handling principles are misapplied, a variety of costly manufacturing defects can occur. Understanding the root causes of these defects is the first step toward troubleshooting a production line. Defect Type Description Primary Root Cause Common Solution Folds or creases formed in the web during transport.
A truly exhaustive handbook on this topic should not just be theoretical. It must bridge the gap between academic physics and practical shop-floor realities, featuring:
