The role of a pull roller in a web machine is identified. The ability of pull rollers, plain or vacuum type, to permit tension differences is explained. Three types of pull rollers are described. Among them is the un-ported roller that utilizes holes and grooves to increase effectiveness. This paper, while providing theoretical and experimental details on pull roller design, will also serve as a useful tutorial for those interested in learning about the practical design and operational aspects of pull rollers.
