Abstract
In a process for the winding of coils into axial slots disposed on the outer perimeter of rotationally symmetric bodies of electrical devices, at least one wire, guided by a winding arm movable about an axis of rotation perpendicular to the axis of rotation of the body, is laid into the slots via a winding form. The body is turned about its axis of rotation by the space of at least one slot after each laying of the wire into an initial slot, accomplished by an initial swinging motion of the winding arm about its axis of rotation, with the wire being laid into a second slot by a second swinging motion opposite to the first and guided back to the start of the first slot after the laying into the second slot for the formation of a coil winding by additional turning. A suitable winding form has a wire-guiding slit that ends in an undercut slot whose undercut surfaces fix the wire on the base of the slot until the completion of the following swinging motion of the winding arm.
