ABSTRACT:
The invention comprises apparatus for forming nelical coils from conductive strip metal, counting the turns and cutting them to separate the turns into coils of desired numbers of turns, annealing the coils, tabbing the ends thereof, coating the coils with insulative coating and curing the coating by baking; compressing the so-insulated coils under extreme pressure to comprise a helical coil product, per se, or to fit conventional cores to comprise an inductor product.
