PURPOSE:To prevent the turbulent air flow in the spinning region, and to enable smooth spinning, by attaching an outer wall capable of stopping the air stream accompanying to a porous moving body to a duct to supply opened fibers to the surface of the porous moving body. CONSTITUTION:The objective suction twist spinning frame is composed of a porous moving body 1, the opening apparatuses 11-14 and the duct to supply opened short fibers to the surface of the moving body 1, the air suction duct 3 placed opposite to the duct 4 at the rear part of the porous moving body 1, and the silver-delivery apparatus 5, 6 to take out the yarn (twisted yarn) formed between the duct 4 and the porous moving body 1. In the outer walls of the fiber-feeding duct 4, the wall at the upstream-side of the moving body 1 is furnished with the accompanying flow-stopping material 16 close to the moving body 1. The upstream-side edge of the stopping material 16a has a sharp angle. |
