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.

Abstract: A press tool for forming a compressible mass into an annulus of given inner and outer diameters and axial length, the tool having radially movable outer and inner tool parts adapted to expand and contract, respectively, to form the mass to the desired inner and outer diameters. An axially movable annular member includes a working face for forming the compressible mass to the desired axial length. Each of the tool parts include a first array of radially movable members, each formed with a head having a working face curved to the desired diameter and a second interposed array of radially movable members also having a head having a working face. A central portion of the working face is curved to the desired diameter and opposed sloping outer portions are shaped for sliding against rear-faces of the heads of respective adjacent members of the first array.
