<p>One disclosed method includes positioning an end of a wire strand adjacent to a propelling mechanism and near a contorted guide tube entry and then propelling the lead end of the wire through the contorted tube. An air passage block and air supply means may be used to established a venturi type effect at the end of the tube. With the wire end positioned adjacent the tube entry, with or without wadding, air injected into the air passage propels the wire. Also disclosed is a method of damping oscillations of wire segments that are being dispensed in a winding plane and the disclosed apparatus includes an oscillation damping plate mounted substantially along winding plane. Another method includes moving a wire clamp adjacent to, and then into the plane; clamping a wire segment; concurrently moving the clamp and a developed coil predetermined amounts, and pulling an extra segment of wire from a wire supply. This is followed by holding the clamp closely adjacent to the winding plane until initial turns for a next coil have been generated. The apparatus includes a clamp assembly characterized by at least six, and preferably eight, distinct movements (or increments of travel) which may be initiated independently, or selectively in combination with each other. In one illustrated form, a clamp jaw moves in forward and reverse modes to open or closed positions; is carried on a first member movable into and out of the winding plane; and the first member is carried by swing mechanism that is movable in forward and reverse modes or direction in at least two different substantially mutually perpendicular planes.</p> |
