Abstract: A method for bending glass sheets is disclosed in which a heated glass sheet (12) is introduced between spaced lower and upper bending platens (16,18). The glass sheet (12) is moved in one direction between the spaced lower and upper bending platens (16,18) during deformation of the platens (16,18) which forms the bent shape in the glass sheet (12). Movement of the glass sheet (12) in the said one direction is continued for at least 1/2 second during a subsequent cooling phase to initiate a freeze in the surfaces of the glass sheet (12) which thereby eliminates mechanical distortion in the formed glass sheet associated with interrupting the movement of the glass sheet (12) prior to cooling.
