ABSTRACT:
A new and improved cloth-board reel is disclosed which utilizes two corrugated sheets bonded together eliminating the need for an intermediary sheet which was previously considered necessary. The cloth-board reel of the present invention provides the required strength without the more expensive construction previously considered necessary. The corrugated sheets are covered with a wrapper sheet which forms a smooth surface for the cloth and adds to the strength of the cloth-board reel.
