Abstract
The invention relates to a method for producing lamellae for a lamellae package, wherein the lamellae are punched from a metal strip by at least one punching die. At least one part of the contour of the lamella is produced by stream cutting. The method is carried out such that the lamella is still held in the metal strip. The lamella is punched out of the metal strip by the punching die. The stream cutting results in clean cutting edges, which do not require reworking of the lamella. The device for carrying out the method according to the invention has a stream cutting unit upstream of the punching press which has at least one stream cutting head. A wide variety of lamella contours can be cut out of the metal strip with high accuracy using said stream cutting unit.
