Title: Automatic gate loading control for stuffer box texturing machine

Abstract: In stuffer box crimping of yarn, yarn is forced into a crimping chamber to form a wad and discharged with a discharge control being varied in response to sensing the position of the wad at the exit of the crimping chamber. The improvement of this invention comprises sensing the position of the yarn wad in the crimping chamber by issuing at least one jet of a fluid aligned to issue across the exit of crimping chamber and receiving the jet in an enlarged orifice communicating with a pressure sensor controller so the yarn wad unfolding point is sensed by interrupting the jet of fluid to thereby regulate the discharge controller with the pressure sensor controller.
