NOTE- This is be an updated version of the paper I gave 5 years ago at the 2012 Oct Conf in Myrtle Beach, SC. Abstract. There is a lot of Science that goes into winding. The winding principles of web Tension, winding Nip and winding Torque are well documented and have been proven and modeled at the Web Handling Research Center at OSU in Stillwater, OK. Yet determining which of these TNT principles, or the proportional amount of each of these to use for proper winding of different types of materials under a specific set of conditions, is still considered an Art. This presentation will present guidelines for selecting the best type of winder to help in consistently winding quality, defect-free rolls of web materials. The presentation discusses each of these TNT winding principles and how they are used on different types of winders. Then a guideline reference table is provided listing various product parameters that each type of Winder is best suited for.
