Abstract

Method for stamping multiple coil sides (96) for a stator winding (18), characterized in that the multiple coil sides (96) are arranged in a grooved row (90), the shaping process taking place at a force (F), the direction of which runs at an angle (α) greater than zero relative to the grooved row (90).
