Inside the tongue guide 10, a mesh belt 8, which is moved by the driving pulley 24 and the interlocking pulley 23, is coupled, and the toe 25 in the hopper 9 is tongue guided. (10) It passes through the inside and serves to feed the upper and lower semicircular guides (4) and (7) inside the upper and lower molded pieces (2) and (5) in the rear part. The upper and lower molded pieces 2 and 5 form upper and lower semi-circle guides 4 and 7 through which the tow 25 and the mesh belt 8 pass, and the upper and lower semi-circle guides 4 The upper and lower steam supply holes 3 and 6 for supplying steam to the tow 25 are formed in the element element of 7), and the steam guide hole 6 is provided below the lower steam supply hole 6. ') Is formed so that the steam supplied to the external steam supply pipe 12 is supplied to the upper and lower steam supply hole (3) (6) along the steam passage 13, the upper and lower The steam supplied to the steam supply holes 3 and 6 is injected onto the surface of the tow 25 to melt the outer circumferential surface of the tow 25. In addition, an intermediate guide body 16 that forms an intermediate semicircular guide 16 'is installed at the rear side of the upper molded piece 2 to guide the movement of the tow 25, and the intermediate guide body 16 On the rear side, a ridge removal piece 18 for removing the ridge 25 'formed at the upper end of the toe 25 is fixed to the fixing piece 17 with a fixing pin 19. And the rear side of the ridge removal piece 18 is provided with a fixed body 20 that forms the cooling tube 21 to force the tow 25 passing through the semi-circular guide 20 'of the fixed body 20. The toe filter rod 22 was obtained by cooling. On the other hand, the condensate receiver 14 and the outlet 15 are provided in the base 1 in the lower part of the intermediate guide 16 and the fixed body 20.

Referring to the effects of the present invention as described above are as follows.

First, when the operation button is pressed, the mesh type belt 8 is moved while the driving pulley 24 and the interlocking pulley 23 are rotated by the rotation of the motor (not shown), and the mesh type belt 8 ) Passes through the tongue guide 10 and the upper and lower semicircle guides 4 and 7 formed on the upper and lower molded pieces 2 and 5, and then the middle semicircle guide 16 'of the intermediate guide body 16. And move through the semi-circular guide 20 'of the fixture 20. On the other hand, the tow 25 in the state in which the plasticizer is added in the previous step is introduced through the injection hopper 9 on one side of the gas 1, and is then guided into the tongue guide 10. At this time, since the tongue guide 10 is tapered, the toe 25 is compressed into a circular shape while passing through the end portion of the tongue guide 10, and the tongue guide is moved by the movement of the mesh belt 8. It exits from (10), and enters the upper and lower semicircle guides 4 and 7 formed in the upper and lower molding pieces 2 and 5. When the tow 25 enters the upper and lower half circle guides 4 and 7 together with the mesh belt 8, the steam supplied to the external steam supply pipe 12 passes through the steam passage 13. To the steam guide hole (6 '), and the steam is supplied to the lower steam supply hole (6) and the upper steam supply hole (3) as shown in Figure 3 tow 25 and the mesh type Steam comes into contact with the belt 8 in the 360-degree direction.
