Abstract

See full text

A method of tempering a plate workpiece entails first fitting the plate workpiece with a shield between first and second shield parts each having a respective mask element so as to cover only an edge region of the workpiece while leaving a more central region of the workpiece exposed. The shield and workpiece are then put in an oven with the plate workpiece fitted between the first and second shield parts. The shield also comprises first and second seals on the first and second parts confronting each other and each displaceable on the respective part between a closely juxtaposed working position in which inner portions of the seals are spaced apart by a distance equal generally to a thickness of the plate workpiece and outer portions of the seal bear on each other and a starting position spaced more widely from and out of engagement with each other. The seals engage and clamp the workpiece in the working position.
