ABSTRACT:
High speed bonding of wound electric components, and particularly armatures, having coils wound from bondable wire is obtained by providing a component support table having equally-spaced component-receiving stations and repeatedly indexing the table in a predetermined direction through predetermined increments. Plural wound and unbonded electric components are loaded in plural, mutually-adjacent stations on the table. After loading a first predetermined number of wound electric components, and while continuing to index the support table, an electric current is applied to the coils thereof to cause the coils of the first set of components to be heated and bonded while a second set of components is being loaded into successive stations. The application of electric current is accomplished by the use of a bonding head plate that is movable toward and away from the support table and rotates with the support table while electric current is supplied to the coils being bonded. An armature orienting mechanism is provided if needed to ensure proper electrical connection of the bonding heads to commutator bars.
