A multiple stage wire drawing system with a plurality of pivotal dancer pulleys, each operable for maintaining wire stock tension between stages and for feeding wire stock downwardly along a generally helical path from an upper guide pulley receiving wire stock from a preceding draw block to a lower coaxial guide pulley aligned for guiding wire stock to a succeeding die block. Each pivotal dancer pulley is mounted via a support rotor on a relatively short pivot arm and for rotation about an axis inclined to its pivot axis, and a toggle type linkage is connected to the dancer pulley support rotor for controlling the angular relationship of the inclined dancer pulley to the coaxial guide pulleys.
