Abstract
A quick change lap retaining device uses radially displaceable blades to engage a groove in the underside of a lap and thereby hold the lap in position. The device fails in the engaged position to prevent inadvertent movement of the lap. Removal of the lap occasioned by disengagement of the blades is preferentially by pneumatic drive but can also be manual.
