Abstract
Abstract The head plate has a rectangular body with a central portion. The connecting portion of the flexible hinge part is integral with the central portion or the central portion is provided with a recess or slot into which the connecting portion is received. The upper and lower surfaces of the central portion of the body are substantially continuous and uninterrupted so as to provide maximum surface area for bonding to the casting material layers. The upper and lower surfaces may be provided with teeth or splines to increase the area of the bonding surfaces.
