Patent attributes
A support assembly is provided for a roller tube that holds sheet material. The support assembly has opposed first and second mounts adapted to support the roller tube when rotatably coupled to the mounts. The mounts can include slides having a slide member that slides within a slide bracket. A support cradle is disposed between the first and second mounts. The support cradle is configured to support the roller tube along a length thereof. Various spring elements can be arranged to apply a force to the roller tube in an upward direction when the roller tube is positioned to dispense material therefrom in a downward direction, thereby preventing the sheet material from telescoping and/or from dragging or binding against the support cradle as it winds and/or unwinds, while also keeping the material from being wound tighter at the ends than across the rest of the roller tube.
