Add to ORKGWeb spreading systems are governed by a universal set of web handling principles such as bending, minimal energy path, normal entry, and traction. These laws, which apply for all web materials and spreading systems, can be used to understand the influences which affect spreader operation.This report covers the mechanics of spreaders such as: bowed rollers, dual bowed rollers, concave rollers, expander rollers, D-bars, Pos-Z^TM bars and more. Also covered are spreader design considerations and troubleshooting techniques
