Abstract
A laminated plate assembly in which the laminations in a stack are secured together by means of one or more interlocks or tabs that project from the uppermost lamination in the assembly through holes or slots in all the other laminations in the assembly, or around the periphery of the other laminations in the assembly, with each tab being bent or pressed against the underside of the bottom lamination in the assembly. This secures all the laminations in the stack together, much like a staple secures papers in a stack together, allowing for additional handling and processing of the laminated plate assembly without concern that the laminated plates in the stack will become misaligned or even become removed from the stack.
