Abstract
An apparatus for wave winding, forming and transferring a coil and for inserting the coil into the slots of a stator core. The coil is first wound on a coil form. After this, a pair of forming arms having wire formers mounted thereon to form a plurality of loops in the coil. Before the coil is stripped from the coil form, coil insertion tooling is moved relative to the coil form. The forming device includes apertures into which a pair of the insertion tooling blades are inserted whereby part of the wire formers will be located inside the insertion tooling blade array and part of the wire formers will be located outside of the blade array.
