ABSTRACT:
A multifinger contact device is produced by a series of deforming stations which compress the fingers into die cavities decreasing the width of the fingers while severing the adjacent fingers from one another, by deforming the adjacent fingers first in one direction and then in the other to decrease the formation of burrs. A subsequent forming station may be utilized to confine the entire periphery of the finger so as to form opposing longitudinal edges on adjacent fingers into noncontacting curved surfaces.
