The handbook is designed to bridge the gap between theoretical research and practical shop-floor applications. It covers the entire lifecycle of a "web"—defined as a long, thin, flexible material like paper, plastic film, metal foil, or textiles—from its initial manufacture to final converting processes such as coating, laminating, and printing.
To prevent structural defects in a wound roll, winding tension must decrease as the roll diameter increases. This is known as tension control: T ension (Winding tension) A iropressure (Nip load pressure) P orosity (Managing air entrainment) E ffective R adius (Tracking roll growth) Common Winding Defects
