Abstract
An apparatus for chamfering the outer edges of stacked printed circuit boards comprises a detecting device for detecting the boundary between two adjacent boards, and a chamfering tool positionable adjacent to the opposed outer edges of respective ones of the two adjacent boards in response to detection of the boundary and movable along the board outer edges to simultaneously chamfer both outer edges. The chamfering tool successively chamfers pairs of opposed outer edges in the upward direction on one side of the stack, and then the stack is turned so that the chamfering tool chamfers the outer edges on a different side of the stack printed circuit boards.
