Set to 45, 55, 60, 80 (mm), and for suction mechanism 5
When a compressed air of 10 kg / cm 2 was supplied and a polyester denier yarn of 1500 denier was run at 400 m / min or more and the yarn was cut and sucked, the yarns with the interval dimensions (L) and (H) Table 1 shows the relationship between the success rate of suction and the suction rate.

Table 1 shows the suction success rate when the distance (L) from the yarn running position to the compressed air jet nozzle hole 5b of the suction mechanism 5 is set to 25 (106 mm) at 0 (mm).

のが最も好ましいことがわかる。 As is clear from Table 1 above, the horizontal distance (L) from the yarn running position to the compressed air jet nozzle hole 5b of the suction mechanism 5 and the vertical distance (H) between the suction mechanism and the cutting mechanism. ) With H / L = 0.7, the yarn suction success rate becomes 74-98%, and it is understood that it is most preferable to set in the range of H / L = 0.7-10.

率が悪くなることがわかる。On the other hand, the relationship between the horizontal gap (L) from the yarn running position to the compressed air jet nozzle hole 5b of the suction mechanism 5 and the vertical gap (H) between the suction mechanism and the cutting mechanism is expressed as follows. When H / L <0.5, the yarn 10 sucked from the suction port 5a
Ends of the compressed air injection nozzle hole 5b does not reach the nozzle hole 5b
The delivery force due to the compressed air ejected from the chamber hardly acts, and the suction success rate is extremely low at 25% to 30%. On the contrary, the relationship between the horizontal distance (L) from the yarn running position to the compressed air jet nozzle hole 5b and the vertical distance (H) between the suction mechanism and the cutting mechanism is expressed as H / When L ≧ 11 or more, the length of the yarn to be sucked becomes long and the yarn 10 sucked from the suction port 5a is entangled and jammed while moving to the compressed air jet nozzle hole 5b portion. Similarly, it can be seen that the suction success rate deteriorates.

さらに、機台における設置スペースに制限があるため、
該吸引機構と切断機構までの寸法（Ｈ）を大きくするこ
とができない。Furthermore, due to the limited installation space on the machine base,
It is not possible to increase the dimension (H) between the suction mechanism and the cutting mechanism.

尚、糸条の走行速度が吸引機構の吸引能力以内であれば
各間隔寸法（Ｌ）、（Ｈ）の設定にほとんど影響しなか
った。If the traveling speed of the yarn is within the suction capacity of the suction mechanism, it has almost no effect on the setting of the interval dimensions (L) and (H).
