PURPOSE:To improve the accuracy of the integrated motion of a means for pressing and releasing a pair of aprons and a means for opening and closing a suction pipe in the air jet twisting spinning apparatus, by connecting both means with an elastic connector. CONSTITUTION:The air jet spinning apparatus is furnished with the apron apparatus 20 wherein the upstream rollers 22, 28 of a pair of aprons 28, 30 are nipped and the downstream rollers 23, 29 are able to be pressed and released, and an air action apparatus 21 furnished with a guide tube 21a having the side suction pipe 40 and a fluid twisting nozzle 21b. In the above spinning apparatus, the parts 24-26 to press or release the apron roller 23 and another apron roller 29 are connected with the elastic connector 31 to the parts 33-38 to block the suction tube 40. The downstream side of the aprons 27, 30 are opened, the suction pipe 40 is opened, and the fiber is allowed to be sucked toward the suction pipe 40 at the start of the spinning, and when the spinning becomes stationary state, the downstream side of the aprons is pressed together, the suction pipe is closed, and the spun yarn is guided toward the twisting nozzle 5b. |
