Abstract: A dry lubricated wire drawing and cooling apparatus comprising a die holder supporting a pair of dies in coaxially aligned and axially spaced relation. The die holder and dies cooperate to define a cooling chamber through which cooling liquid is circulated and drawn wire is constrained to pass. A sensing device detects approach of a wire end and operates mechanism to shutdown the apparatus and expel cooling liquid from the cooling chamber before the wire end reaches the first one of the dies.

Abstract: A multiple stage wire drawing machine having a final stage draw block and a plurality of multiple step draw capstan assemblies each having a plurality of coaxial draw capstans of increasing diameter rotatably mounted on a drive spindle, driven at a fixed angular rate relative to the final stage draw block, and independently driven by the spindle through friction disc slip couplings at substantially the same slip drive torque.

Abstract: 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.
