Abstract
A telescoping roll stand for use in an extrusion line includes a linkage connecting one or more auxiliary rolls in a spatial relationship relative to each other and other auxiliary web processing components, including conveyors, load cell rolls, draw rolls, and other web handling components, when one of the auxiliary rolls is shifted in relation to a primary roll.
