A device for applying tension to wire, especially wire of fine diameter as it is unwound at high speeds over an axial end of a spool of wire. The tensioning device is effective to prevent curling and twisting of the wire as it is unwound. It is also useful in tensioning wire during high speed winding where the wire is rapidly accelerated and decelerated. The wire control device includes a disc having a plurality of radially extending filaments which protrude beyond the periphery of the axial end of the spool of wire and engage the wire as it is unwound over the axial end of the spool. A cylindrical shaped tubular member encircles the disc and engages the ends of the filaments to bend them so that they extend in a direction which is axially and outwardly of the spool in the direction of movement of the wire being uncoiled. The wire being uncoiled from the spool engages the bent ends of the filaments.
