Abstract: A device for winding up elongated flexible belts comprising a reel of generally square cross-section rotatably mounted on a frame member and extending laterally from one side thereof. A crank extends from the other side and a pair of guide rollers are aligned with the reel parallel to the axis thereof and spaced closely enough to prevent twisting of the belt and to re-orient lengths of the belt which were previously twisted. The frame member is secured onto a mounting bracket so that the crank can be operated from either the right or left hand side.
