ABSTRACT:
A display device wherein a pleated sheet is retained in a carrier defining opposed pockets receiving the opposite ends of the pleated sheet. Stops are provided at opposite sides of the carrier for engagement by opposite side portions of the pleated sheet for limiting lateral expansion of the pleated sheet. The spacing between the stops is preselected to maintain the folds of the pleated sheet suitably compressed to have a height substantially equal to the depth of the pockets.
