Comparison of center and surface winding using the wound-in-tension method
Abstract
Pfeiffer first defined the wound-in-tension measurement in 1968[1]. This technique requires the outer layer of web to be pulled away from a winding roll and a measure of the web tension is made prior to returning the web to the surface of the winding roll. In this manner the wound-in-tension can be studied as a function of winder type and as a function of winder and web line operating parameters. In this paper the use of the WIT measurement as a non-interfering method of evaluating roll structure will be examined. WIT will be used to compare surface winding and center winding with a nip. The nip-induced-tension components of the WIT will be determined as well and compared for the different winder types.
