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.
