ABSTRACT:
A method of manufacturing an elongate stack of interlocked laminae in a die assembly. The method includes the steps of stamping a first lamina having generally opposed first and second edges in the strip stock material, stamping at least one first interlock means for engaging another lamina in the first lamina, separating the first lamina from the strip stock material, placing the first lamina into the choke passageway, the first and second edges of the first lamina frictionally engaging the choke passageway, stamping a second lamina having first and second elongate edges in the strip stock material, stamping at least one second interlock means for engaging another lamina in the second lamina, at least partially engaging the first and second interlocking means, separating the second lamina from the strip stock material, placing the second lamina into the choke passageway, and frictionally engaging the choke passageway along the first and second elongate edges of only one of the first and second laminae.
