Abstract
A roll commutator for electric motors has a plurality of bars adjacent to one another and produced from a continuous metal section. The metal section already has projections on one of its sides before the production of the bars, which projections serve as anchoring claws after rolling up the line portions produced from the metal section. Additional tools and processing steps are not needed since it is not necessary to process the claws when manufacturing the roll commutator.
