Abstract: The apparatus comprises a coiling spindle having an axial passageway for periodic movement therethrough of a filament containing a mandrel. The free end of a supply of support wire is temporarily clamped in a slot at the periphery of the spindle which has a die at its end face such that, upon rotation of the spindle, the wire is coiled first around the periphery thereof and then around a generally spiral track in said end face and then down between turns of the filament. A reversing finger member then urges the wire back in the opposite direction to form a locking overwind which is then severed from the supply of support wire. A pressure finger member is then pressed against the outer helical turns on the spindle to partially set the turns and minimize opening or offsetting thereof relative to the filament.
