  • High voltage coil winding machine
    Patent number: 4901773
    Abstract: The coil winding machine (10) winds a series of interconnected coil bundles within winding forms (28). The winding forms are transferred from a coil winding station (29), at which the coil is wound in the pie-shaped cavity of the winding form, to a coil removal station (237,293,61), at which the winding form is separated and the coil is removed and placed on a storage arbor (54) in the proper order for later assembly in a transformer, and finally, after reassembly of the winding form, back to the winding station.
