ABSTRACT:
An arrangement whereby a plurality of coils may be simultaneously formed on a common coil form and thereafter that form sliced or sectioned to yield individual coils is disclosed employing an elongated hollow coil form of insulating material with a plurality of lateral surface openings spaced therealong and extending in the direction of elongation. A conductive strip extends along the surface of the coil form and has a plurality of conductive tabs extending from the strip and through corresponding coil form openings into the hollow interior of the form. A plurality of wire ends are attached to the conductive strip and the coil form rotated to generate the plurality of coils thereon. A second conductive strip may be placed along the formed coils for terminating the other coil lead so that when individual coils are severed from the form, convenient terminals connected to the beginning and terminus of the coil are available for connecting the coil in circuit with other components.
