A method and apparatus for automatically forming stacks of mechanically interlocked laminated members comprises a punch and die assembly for forming one or more stacks of laminates of the same or different shapes and means associated with one of the laminate dies for measuring stack height to a predetermined dimension. When the desired stack height is reached, the measuring means, which is preferably an optical sensor, transmits a signal to responsive means which, in turn, activates an air cylinder and a slide cam carried by the punch assembly to recycle the operation by commencing the formation of a next stack of laminated members. Improved mechanical interlocking and stacking density is obtained by coining the areas of the mechanical interlocks prior to formation of bow tie shaped interlocks within the punch and die assembly.
