Abstract

- a tube for being positioned with respect to a vertical portion of a screen;
- a mechanism attached to a top edge of the screen and to the tube for coupling the screen to the tube;
- and
- a smoothing edge feature for being positioned parallel to the tube,
- wherein the tube is rotatable about a vertical axis for drawing the screen over the smoothing edge feature and causing the screen to wind up onto the tube.
