Web20180e - Time Constants - Roll Shape

In the last 4 episodes, we have discussed moisture and temperature changes in webs and wound rolls. This week we do something very different, that is to describe how long it takes for a wound roll to get out of shape during storage and handling. My 10th book, the must-have, 750 page, Web Handling Handbook, is available through Destech as both print and e-book. https://www.destechpub.com/product/web-handling-handbook/ https://www.youtube.com/watch?v=u3gA8RmTARA You can buy unlimited lifetime access to nearly everything I own copyright to. This includes some 500 videos, including my two-day web handling and two-day winding courses, 400+ short clips on web handling, converting, winding, machine/control design, and industrial problem solving. It includes two searchable databases listing nearly everything published except patents. Finally, it also includes thousands of other pages of reference materials, all for only $2K US.
