Drop cloth systems and methods of using same
Abstract:
Drop cloth systems include drop cloths having edge supports extending along two opposite edges of the drop cloths for preventing folding of the opposite edges along which the edge supports extend. Extending between the edge supports is at least one spring strip having the property of being substantially straight when unwound to maintain the drop cloths substantially spread out on the surface area to be protected. Also the spring strips have the property of being windable to permit the drop cloths to be rolled up from one of the opposite edges along which the edge supports extend for easy storage and transportation when not in use.
