Abstract
Producing wave winding wires for a coil winding of an electrical machine via flat winding. A row of shaping elements, each having a holder for a straight wire section of a wire and a bending mold for shaping a wave winding head region between the straight wire sections, are moved in a linear manner relative to one another on a linear guide mechanism and are rotated about a respective axis of rotation, in order to form a meandering wave winding wire with straight wire sections and chevron-shaped wave winding heads in between by rotating neighboring shaping elements in opposite directions with their axes of rotation converging. A change in spacing of the linear guides is converted in the rotational movement of the shaping elements. A bending of the wire ends of the wire is carried out before the meandering bending of the wave wire winding.
