Individual laminas are blanked from sheet strip material and stacked to form a lamina stack for use in electric motor or generator rotors or stators. m e thickness of each lamina is measured prior to stacking, and the individual lamina thickness measurements are supplied to a controller. The controller monitors the increase in stack height as the individual laminas are stacked and compares the increase in stack height to an operator entered preselected stack height. Individual laminas are stacked as long as the height of the lamina stack is less than an operator entered preselected stack height. Individual laminas are continually stacked until the addition of another lamina would cause the lamina stack height to exceed the preselected stack height. Slotted openings are blanked in each lamina to form a slot in the stacked laminas which is skewed to the stack axis by a constant skew angle by providing that the lamina stack is rotated an angular increment determined by the thickness of the lamina prior to stacking the lamina.
