Abstract: The invention relates to a drywall corner bead spreader device. The device comprises a stationary support portion and a movable pressure applying portion. When a length of drywall corner bead is placed on the stationary support portion with its flanges facing upwardly adjustment of the movable pressure applying portion into contact with the flanges will force the flanges to assume an included angle greater than its normal ninety degree orientation. The movable pressure applying portion includes a freely rotating spreader ball which will rotate as the corner bead is pulled from beneath the spreader ball resulting in reduced friction and providing a uniform included angle to the flanges in excess of ninety degrees.
