Abstract
A method and apparatus in which wave windings, cut from a continuously formed wave winding band, are brought with a defined number of waves essentially tangentially to a rotor or stator lamination packet or a rotorlike transfer tool having radially outwardly open slots. During a rotary motion of the lamination packet or transfer tool and a substantially tangential relative motion, at a speed corresponding to the circumferential speed of the rotary motion, the straight portions of the bandlike wave windings are pressed into the slots.
