Abstract
A safety chuck mounted to equipment that process web material is provided. The safety chuck is provided with a die spring connecting a moveable jaw with a spindle, said spring urging the moveable jaw into a fully closed position. A number of magnets mounted on a mounting flange will engage the moveable jaw, overcoming the spring's force and holding the moveable jaw in a fully open position. Rotation of the spindle releases the magnets allowing the spring to force the moveable jaw back into a fully closed position.
