Abstract: A stack of glass blanks is moved on a support into position beneath a head carrying a cutting tool. The uppermost blank is scored by the cutting tool under quidance of a templet and the tool withdrawn. Pick-up means, advantageously with suction cups, removes the scored blank laterally from the stack and the stack and cutting head are brought closer together by a distance equal to the thickness of a blank, preferably by raising the stack support. The next blank is then scored and the operation repeated until all the blanks in the stack have been scored and removed, whereupon a new stack is brought into position. Means are provided for centering the stack with respect to the cutting head, and centering means adjacent the top of the stack centers the uppermost blank with respect to the cutting head, advantageously by jack means positioned on the sides of the stack.
