ABSTRACT:
A web backing support interconnecting tubular housings in spaced relation, extends through slots formed in extensions of closure caps coaxially mounted on the ends of the tubular housings to render the caps non-rotatable. Adjusting knobs axially fixed to scroll shafts rotationally supported by the end caps, within the tubular housings, are engaged by the end caps under spring bias to resist rotation of the scroll shafts and thereby yieldably hold the web in adjusted positions.
