Abstract

PURPOSE:At the start of spinning operation in a spinning frame provided with air-jetting nozzles and flase-twisters, the bundle of fibers is passed through the nozzle and threaded around the flase twister, as the rotating air stream is allowed to act on the fiber bundle, to permit simple and steady threading operations. CONSTITUTION:In a spinning frame provided with air-jetting nozzle 6 for allowing a rotating air stream to act on a bundle of fibers S and a false twister 8 of a contact type such as a belt or friction type, the bundle of staple fibers is drafted in the drafting part 1, then treaded around the twisting part to start spinning where a suction gun 16 is provided so that it has the nozzle part 17 which allows the air to rotate in the reverse direction to that by the gun 16. The nozzle part 17 is set to the downstream immediately next to the nozzle 16 and the bundle S is allowed to pass through from the drafing part 1, then as it is held by sucking and introduced into the gap between a couple of belts 13 and 14, which are kept separated. Then, both belts are allowed to contact to the bundle S to start spinning operation and, when it becomes in the steady state, the yarn is transferred from the suction gun 16 to the winder B.

The above-mentioned false twisting device does not false-twist the yarn using compressed air, but refers to a device that twists the yarn by directly contacting the staple fiber bundle, such as the known belt type or friction type. This is called a false twisting device. It has been confirmed that when this contact-type false twisting device is applied to a spinning machine in combination with a nozzle, it may be possible to perform spinning at a much higher speed than a conventional pneumatic spinning machine.

First, all parts of the pneumatic spinning machine are driven simultaneously, and the belt-type false-twisting device (8) is operated to twist both false-twisting belts (11).
(12) are kept separated from each other. Next, the staple fiber bundle (S) is pulled out from a can or the like (not shown), introduced into the draft device (1) from behind the back roller (2), and then passed through the air injection nozzle (6). (16) to aspirate. The staple fiber bundle (S) is connected to the front roller (5) and the air injection nozzle (
By keeping the nozzles (6) and (6) close to each other, the nozzle (
6) The population (force) is easily introduced into the nozzle (
By ejecting the swirling air flow of 6) in a spiral manner toward the nozzle outlet (15), it easily passes through the air injection nozzle (6). The state at this time is shown in Figure 1,
Staple fiber bundle (S) is suction gun (16)
At the same time, the swirling air flow of the nozzle part (17) causes false twisting in the same direction as in the case of the false twisting device (8).

Next, the suction gun (16) is moved to pass the fiber bundle (S) onto the double plate twisting belt (
After being positioned between 11 and 12, the false twisting device (8) is operated to bring the two plate twisting belts (il) (12) into contact with each other at a constant pressure to start false twisting. From this moment on, the false twisting belts (11) and (12) strongly twist the staple fiber bundle (S), but the fiber bundle (S) is previously twisted in the same direction as the false twisting device (8) by a suction gun C16). After the nine-fold staple fiber bundle (S), which is false-twisted, does not cause sudden twist fluctuations and is not easily cut, is passed through the delivery roller (9) as shown in Fig. 2. By threading the yarn onto the empty bobbin CB), winding of the spun yarn (G) is started, and the normal operating state shown in FIG. 3 is established.

In addition, in carrying out this method, it is necessary to arrange the draft device (1), the air injection nozzle (6), the false twisting device (8), and the delivery roller (9) in a straight line with each other to ensure smooth propagation of the twist. This is preferable in order to speed up and obtain a high quality spun yarn, and it is also preferable to move the suction gun (16) along the above-mentioned straight line as much as possible when threading, in order to prevent the thread cutter from forming.
