Tension automatic adjustment device for synthetic fiber stretcher

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an automatic tension adjusting device provided on a cryler of a synthetic fiber stretching machine.;It was invented to minimize the fluctuation of the marine tension by preventing the tangling caused by the yarn flowing down at the start of the yarn lowering operation or the starting operation after the replacement operation when the yarn threading occurs in the operation of the synthetic fiber stretching machine. So as to provide tension to the yarn along the center of gravity of the acrylic round bar 43 and prevent the yarn from falling down by engaging the yarn in the recess 42 ' It is possible to maintain quality and improve quality.
