ABSTRACT:
Flexible sheets are clamped between anchoring bars and supported in a flat condition on a rectangular frame formed by a pair of spring bands interconnecting the anchoring bars with a rest bar. The sheets are rolled up into tubular form assisted by the coiling of the spring bands. The free ends of the sheets overlying the rest bar are clamped to the rest bar and retainer spring bands pivoted to the rest bar are coiled about the rolled up sheets to hold the same in a storage condition.
