Apparatus for forming wave windings for rotor and stator lamination packets of electrical machines
First Claim
1. An apparatus havinga forming device for forming a wave winding band anda device for introducing wave windings cut from this band into radially outwardly open slots of a cylinder member which is one of a rotor or stator lamination packet or a similar transfer tool,characterized in that the forming device for the wave winding band hasa rotatable device which is one of two rotatable disks or one rotatable roller andtwo rows of forming protrusions distributed uniformly over the circumference of the rotatable device and offset from one another relative to the respectively other row and protruding past the circumference of the rotatable device, anda wire guide guided in such a way that a winding wire can be placed in undulating fashion in alternation about outer side faces of the successive forming protrusions on the circumference, the outer side faces having a shape which corresponds to a shape to be generated of winding heads of the wave windings.

Abstract
An apparatus in which wave windings with a defined number of waves are cut from a continuously formed wave winding band. In forming with a wire guide, the wave winding band is laid in alternation around the outer side faces of forming protrusions, offset from one another on the circumference of two disks. The two disks can be driven to rotate. In the angular range in which the wave winding band is driven on the circumference of the disks or roller, the spacing between one forming protrusion of one row and the next forming protrusion in the other row is increased by such an amount that the outer side faces of the forming protrusions form the winding heads of the wave windings. The wave windings cut from the wave winding band are introduced into radially outwardly open slots of a lamination packet or a rotorlike transfer tool.
