6 is wound in an untreated white background state. Code 1
0 is drawn out at a constant speed by the first drive roll 17 having a speed control device, and is introduced into the pre-dip tank 18. , A roll 19 arranged in a pre-dip tank 18
The immersion treatment is performed by passing through the treatment liquid 20 while being wound around.

Further, the cord 10 enters the oven 7a,
The return rolls 12 and 13 disposed at both front and rear ends of the oven 7a are heated and dried by reciprocating several times, then cooled in the atmosphere outside the oven 7a, and transferred to the second drive roll 22 for pre-dip processing. Finish part 2. Second drive roll 2
Numeral 2 has a speed control function based on the first drive roll 17 and applies an optimal tension to the cord 10 in the pre-dip processing unit 2.

Hereinafter, similarly, the cord 10 is connected to the RFL tank 24.
Is heat-set in the oven 7b from the roll 25 disposed therein via the third drive roll 26. After the heat-set cord 10 is sent to the soaking tank 28 via the fourth drive roll 27, the rolls 28, 29,

Turning between

The running cord 10 is clamped below the shaft 45. The head of the revolving plate 43 is fitted with a bolt 48 having a knob 47 and fixed with a nut 49. In order to simultaneously rotate the pair of revolving plates 43, a pin 50 is inserted in parallel, and the pin 50 is vertically inserted. Are fixed by screws 51 inserted into the holes. Since the two revolving plates 43 are fastened to the bolts 48 at different screw pitches, the bolts 48 are rotated by rotating the knob 47, and the interval between the revolving plates 43 can be adjusted by the different screw pitches. it can.

A detecting member 55 composed of a proximity switch is fixed on the support 44 between the reinforcing member 56 and the turning plate 43, and detects the rotation of the turning plate 43. An elastic member 57 such as a coil spring is stretched between the screw 51 and the screw 58 disposed on the top of the reinforcing member 56, and constantly pulls the turning plate 43 toward the detecting member 55.
