[0004]

In the above-mentioned conventional air processing machine 101, the first feed roller 103, the second feed roller 105, the stretching pin 107,
109, the third feed roller 111, the fourth feed roller 113, the preheater 115, and the air processing section 117 are arranged in order from the top to the bottom, so that the height of the machine is inevitably increased, and the threading operation is troublesome. And the workability is poor.

Further, during high-speed yarn processing, the yarns Y1 and Y2 are formed by the preheater entrance guide G1 and the preheater exit guide G.
2 and the air resistance between the pre-heater 115 and the air processing portion 117 easily vibrate between the third feed roller 111 and the fourth feed roller 113 and the air processing portion 117, and uniformly contact the pre-heater 115. Without this, there is a problem that uniform presetting is not performed.
Further, since the pre-set by bringing the pre-heater 115 into contact with the pre-heater 115, when POY (partially drawn yarn) is used as the yarn to be processed, there is a problem that only a low shrinkage yarn of up to 8% can be formed.

In the latter air processing machine 127, four hot rollers 129 are used as feed rollers.
Since 133, 137 and 141 are used, there is a problem that the manufacturing cost is high. In addition, since the thread is wound around the hot rollers 129, 133, 137, and 141 at least several to ten and several times, there is a problem that the threading operation is troublesome. Since the set heater 151 is arranged vertically, there is a problem that the height of the machine is high and the workability of thread hooking is poor.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and has as its object the advantage that the threading operation does not take much trouble and effort as compared with the prior art, and that the height of the machine is not so high. Another object of the present invention is to provide an air processing machine capable of performing any processing.
