In a method of making a pencil core having a plurality of substantially flat laminations wherein at least one lamination at the center of the core is wider than the other laminations, a flat strip of core steel is fed into a progressive die, and a plurality of scrap region blanking stations is provided each of which blank out two spaced parallel regions from the strip, but with each of the scrap region blanking stations blanking out the regions at a different spacing. At an embossing station, at least one embossment is provided in at least each of the laminations preceding the last lamination. After all of the scrap region blanking stations, a blanking and stacking station first blanks laminations free from the strip at and corresponding to the parallel scrap regions of different spacing, and as each lamination is blanked free from the strip, that lamination is stacked onto the previously blanked laminations to form completed cores, the completed cores being held in a choking section of the blanking and stacking station. This die can also have multiple rows.
