PURPOSE:To prevent the turbulent air flow in a wedge-shaped space for spinning and to enable smooth spinning, by attaching an outer wall capable of stopping the air stream flowing into the wedge-shaped space to a duct to supply opened fibers to the wedge-shaped space. CONSTITUTION:The objective suction twist spinning frame is composed of a pair of members 1, 2 arranged adjacently in parallel and rotating of the same direction, the opening apparatus and feeding duct to open and supply short fibers to the wedge-shaped space R formed at the outer surface of the rotary members 1, 2, the apparatus to such the air in the wedge-shaped space R into at least one of the rotary members, and the sliver-delivery apparatus to take out the yarn (twisted yarn) formed in the wedge-shaped space R along the axial direction of the rotary members 1, 2. In the outer walls of the duct 5 of the above apparatus, the wall opposite to the rotary members 2 rotating along the direction toward the wedge-shaped space R is placed close to the rotary member 2, and the edge 12 of the outer wall is sharpened. |
