An apparatus for providing "long ends" on reels of wire is incorporated in a continuous wire spooler. In an illustrative embodiment, continuous spooling is achieved by alternately filling each of a pair of reels while the other, previously filled, reel is removed and replaced with an empty one. The reels are filled with the aid of a wire distributor which is periodically commuted between the two reel positions in order to guide wire from a source to the reel being filled. At each of the reel positions there is provided a reel-receiving arbor including a concentric dummy reel positioned to be axially aligned with and adjacent to a reel which is mounted on the arbor. A chain in a closed loop is movable in a plane perpendicular to the arbor. A portion of the loop is substantially aligned with a corresponding part of the perimeter of the aft flange of the dummy reel. As the chain moves around its track, a guide pin mounted on the chain intercepts wire positioned over the empty reel and moves the wire over the aft flange of the reel and the fore flange of the dummy. Thereafter, a cam striker mounted on the chain closes a relay as it moves along the chain path. The relay causes a throw pin, mounted proximate the arbor to engage the wire and move it into position for snagging. A snagger mounted to a rotatable snagger disc constituting the aft flange of the dummy reel engages the wire for winding onto the dummy reel. Thereafter a second guide pin mounted on the chain intercepts the wire from the distributor and moves it back over the fore flange of the dummy reel and the aft flange of the empty reel. The wire, which is to be spooled on the empty reel, is guided by a shield ring to mate with the empty reel in such a manner as to assure proper engagement therewith. Upon such engagement, a second cam striker on the chain closes a relay, thereby stopping the movement of the chain.
