The fixed support rod is replaced by a friction roller with sanding function in the utility model, so that the filament fiber is sanded before winding to form broken fibers, and high-elastic broken fiber yarn is obtained. The high-elastic broken fiber yarn has a hand feeling like short fibers and physical property indexes better than short fiber yarn, and there is no lint and machine table pollution phenomenon in the production process, and the unwinding is normal, and there is no snarl caused by the appearance of fluff. Large package production can be realized.
