Abstract
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, at least two sheet metal laminations of a magnet core are of a different width extending from one longitudinal edge to the other, and several laminations, which rest against each other, are connected with each other to form the bundle. To simplify the tool control, the two longitudinal edges of a lamination are punched in edge cutting stations, which are separate from each other and are arranged offset in the feed direction of the sheet metal strip. The edge cutting stations for cutting the longitudinal edges have a cutting die and an associated bottom die. The cutting die, together with the bottom die, is displaced for creating different laminate widths.
