Capstan draw apparatus for periodically gripping and drawing an elongated member

A capstan draw apparatus for periodically gripping and drawing an elongated member in a longitudinal path, comprising:

• a plurality of split clamps each including a pair of oppositely disposed, clamping elements for transversely closing and engaging and then transversely opening and disengaging the longitudinally drawn, elongated member;
• a plurality of support carriages each having one of said split clamps positioned thereon;
• an endless capstan chain drive means for longitudinally pulling each of said support carriages in an endless path of rotation, said drive means including first and second endless capstan chains spatially positioned parallel to each other, each of said plurality of support carriages being connected to said pair of capstan chains at different fixed positions along their respective endless lengths;
• an elongated frame means positioned along and on opposite sides of a straight path for successively engaging each of said split clamps for successively closing said split clamps about the elongated member for longitudinally drawing same, and then successively opening and disengaging each of said split clamps from the longitudinally drawn, elongated member;
• and
• an endless lateral guide frame means including first and second oppositely disposed, parallel endless lateral guide frames that are spatially positioned parallel to said endless capstan chains and extend on opposite sides of said plurality of support carriages for continuously supporting each of said support carriages in a positively guided manner for uniform movement thereof throughout their entire endless paths of rotation.
