ABSTRACT:
An elongate roller, movable back and forth transversely across the bed of a truck from one side thereof, has rolled thereon a cover sheet which is unrolled and rerolled during the back and forth movement to cover a load in the truck bed. Levers pivotally mounted at opposite ends of the truck carry the roller and are moved by hydraulic power cylinders controlled from inside the cab of the truck. A special chain and sprocket arrangement drives the roller, and a special elastic drawcord and backup plate arrangement at opposite ends of the truck bed secures and seals the cover sheet at such opposite ends of the truck bed.
