PURPOSE:To facilitate the ending operation in bind-spinning, by using a bind- spinning frame furnished with a mechanism for contacting and separating a pair of rollers of the front roller of the drafting means, and a mechanism for contacting and separating the means for sucking the end of the yarn at the inlet of the air false-twisting nozzle. CONSTITUTION:The objective bind-spinning frame has an air false-twisting nozzle 4 just after the drafting means 1-3. In the above frame, the top roller 3' is attached rotatably to one end of the arm 32 to enable the connection and separation of the top roller 3' of the last front rollers 3, 3' of the drafting means 1-3 and the bottom roller 3, and the other end of the arm 32 is attached swivellably to the frame. Furthermore, an inner tube 14 and the jacket tube 13 are connected slidably between the air suction tube 41 and the yarn end suction tube 15 to enable the connection and separation of the yarn end suction tube 15 and the inlet 4a of the air false-twisting nozzle 4, and the swivelling arm 18 is connected to the bracket 16 attached to the end of the inner tube 14. The arm 32 is made swivellable by the protrusion attached to the bracket 16. The air false- twisting nozzle is preferably made tiltable. |
