Abstract: The present invention relates to a method for manufacturing lamellas (20) from sheet metal (30) for a stack of such lamellas (20), i.e. a lamination, such as the core of a transformer or of a rotor or a stator of an electric machine. According to the present invention, in a first manufacturing step (A), the individual lamellas (20) are only partly cut loose from the sheet material (30), while connecting tabs (32) are left between the lamellas (20) and a remaining frame part (31) of the sheet material (30). As a result, the lamellas (20) can be subsequently processed (SP) separately, favorably without requiring the individual and/or direct handling thereof. Only thereafter, in second manufacturing step according to the present invention (B), the lamellas (20) are completely cut loose from the frame part (31) of the sheet material (30) by cutting the said connecting tabs (32) there between.
