A combination draw ring with a die set is disclosed for use in forming a multi-compartmented tray (10) from a piece of sheet material (118) without tearing or bowing. The draw ring (98) has an outer part (102) for lying on the portion of the sheet material that will become the tray periphery, and an inner part (104) for overlying at least part of the portion of the sheet material that will become the ribs (18, 20, 22) of the tray.
