Abstract

PURPOSE:To improve the performances and efficiency of a speaker by intermittently feeding bobbines so that self-fusible wires are wound on the bobbines and then cut and by bringing the terminals into contact and then bending the same so that the coil terminals may be automatically shaped without any irregularity in the winding number.
