Book Description

An engineering handbook that explains all technical aspects of webs, long thin sheets of materials,such as paper, plastic films, foils, and textiles that are wound into rolls, often after being laminated,printed, or coated. Topics covered include: tension control, roller mechanics, drives, brakes, nip control, guides, spreaders, slitters, and more. The book illustrates engineering principles with shop-floorexamples and provides easy-to-understand calculations that control how web systems are designedand operated, and how webs of many different materials can be made to move efficiently over a varietyof rollers. These tools are meant to help industry specialists troubleshoot and correct defects suchas wrinkles, bagginess, curl, and misshapen wound rolls. As part of web handling the book providesextensive details on many roll-to-roll converting operations, such as calendering, coating, laminating,and printing.
