Patent ID: 7032293

Claim:
In a process for producing bundles of laminated sheet metal for magnet cores, wherein laminations are punched free along two longitudinal edges of a sheet metal strip, wherein at least two laminations of a magnet core have a different width extending from a first longitudinal edge to a second longitudinal edge, and wherein laminations which rest against each other are connected with each other to form the bundles, the improvement comprising: punching the two longitudinal edges of a lamination in edge cutting stations ( 12 , 14 ) which are separate from each other and are arranged offset in a feed direction of the sheet metal strip ( 30 ), the edge cutting stations ( 12 , 14 ) for cutting the longitudinal edges have a cutting die ( 12 . 1 ) and an associated bottom die, the cutting die ( 12 . 1 ) and the bottom die are displaced to create different laminate widths; and punching through-holes out of the laminations for forming sheet metal separation pieces in a follow-on perforating device ( 13 ) between two of the edge cutting stations ( 12 ).
