ABSTRACT:
A method of manufacturing a stack of interlocked laminations in a progressive die assembly having a choke. A strip of sheet stock material is provided and a plurality of laminations are stamped therein. Each of the laminations include at least one interlock feature and include first and second regions and a connecting section extending between the first and second regions. The laminations are separated from the sheet stock material and stacked in the choke with the first and second regions in a first orientation. The laminations are also interlocked substantially concurrently with the separation and stacking of the laminations. The interlocked stack of laminations is removed from the choke with the first and second regions in their first orientation. The stack is then formed into a second shape wherein the first and second regions have a second orientation and the connecting section therebetween has been deformed.
