Abstract
A method to produce rotors or stators of electric machines having radial grooves into which webs of flat windings having parallel webs and winding heads connecting said webs being pulled, wherein a winding is produced on a rotating, strip-shaped flat former shorter than the winding such that windings are pulled off the former and transferred into a linear transfer device, which transports the windings to a removal position at which the windings are transferred into radial grooves of a rotor or of the transfer tool for transfer into radial grooves of a stator, wherein the former, the transfer device, and the rotor or the transfer tool being jointly rotated about an axis of rotation of the former when rotated to form windings.

A method for producing rotors or stators of electric machines, wherein the rotors or stators have radial grooves into which webs of flat windings with parallel webs and winding heads connecting the webs are inserted, the method comprising:
- inserting windings prefabricated on a former and being initially flat into radial grooves of a rotor or a transposing tool configured for passing on the windings into grooves of a stator, the former being a rotating, strip-shaped, flat former shorter than the windings such that first turns of the windings generated are removed from the former before production of the windings is complete;
- transposing turns of the windings removed from the former into a linear transfer device configured for transporting the turns to a removal position;
- and transposing the turns from the removal position into the radial grooves of the rotor or into the radial grooves of the transposing tool for transposition of the winding into the radial grooves of the stator, wherein the former, the transfer device and the rotor or the transposing tool are jointly rotated about an axis of rotation of the former whenever the former is rotated in order to form turns.
