Dynamic Coefficient of Friction Including the Effects of Air Entrainment Between a Roller and Web
Abstract
The dynamic coefficient of friction between polyester and an aluminum roller, and polypropylene and an aluminum roller was determined. The alr fllm that develops between a web and roller prevented the use of any exlstlng coefficient of friction measuring device. Therefore a measuring device was developed that does include the effects of alr entrainment between the web and roller. Each web was tested agalnst the aluminum roller at var 1 ous web ve lac it le s. web tens ions, and wrap angles. The measuring dev lee produced excellent results and any further research looks promising.
