Abstract
The present invention relates to a pin-less registration method for a plurality of laminate elements in a selected stack orientation. The method involves the use of an optical step that images portions of each laminate and determines a required correction factor between an alignment of the laminate element at the pre-alignment station and a preferred stack orientation for the laminate element. A computer operation control system provides instructions for positioning laminate elements to a corrected stack orientation during an assembly of the stack. Following the assembly of the stack an induction welding step occurs at predetermined locations to secure the pinless alignment.
