Which Winder's for You?

摘要

A lot of science goes into winding. So-called TNT (tension, winding, torque) winding principles are well established and have been proven and modeled at the Web Handling Research Center at Oklahoma State University, Stillwater, Okla. Yet determining which of these principles, or the proportional amount of each, to use for proper winding of different types of materials under specific sets of conditions is still considered "art." This article is intended to help processors select the best type of winder to use in order to consistently produce high-quality, defect-free rolls of web material. We will discuss the winding principles, how they are used on different types of winders, and present product parameters for which each type of winder is best suited.
