ABSTRACT:
A new method of automatically positioning opposite ends of a wire is provided. The leading end portion of the wire is clamped to place the wire in a hair-pin configuration and gripped and cut off with the opposite ends aligned correctly. Then, the cut-off wire is moved laterally in a stepwise manner. Between two successive movements the wire ends can be subjected to insulative cover removing process or terminal attaching processes selectively. There is also provided an apparatus for putting the above method into practice. The apparatus comprises means for repeatedly paying out wire from a wire source, a wire reversing body which clamps a wire end portion and reversing the wire end by 180 degrees, means for gripping the wire, and a cutter for cutting off, from the wire, a wire in a hair-pin configuration. The gripping means is moved laterally. Along its movement, a plurality of wire end processing units are aligned.
