A vertical screen winding system comprising:
- a tube for being positioned with respect to a vertical portion of a screen;
- 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.
A method of rolling up a screen vertically, the method comprising:
- positioning a tube vertically at a distance from a screen support structure;
- positioning a smoothing edge feature parallel to the tube;
- passing at least part of the screen over the smoothing edge feature;
