  • the roving bobbins 3 are different from one another in the amount of rovings remaining thereon, and end portions of rovings are not present in certain positions, some hanging down. Therefore, it is necessary to search for and suck in a roving end while maintaining a spacing between the suction nose of each suction nozzle 10 and the corresponding roving bobbin 3 according to the amount of rovings remaining on each individual yarn. In the case where a roving end hangs down, it is necessary to once rotate the bobbin concerned in the winding direction.

Thereafter, the nozzles 10 are retreated to nearly central portions of the roving winding heights and the roving bobbins 3 are rotated in the rewinding direction at high speed, while the rovings are removed by suction. After the lapse of a certain time, the nozzles are again moved to the positions of the auxiliary winding members 3b and the rovings remaining thereon are removed by suction.

After the search and suction of roving ends, the box 11 is retreated, whereby the aforesaid holding of the positions is released.

  • a front-side annular seat 36 which supports the nozzle 10 slidably is inserted beforehand into the nozzle, and at the time of mounting to the nozzle holding box 11, a smaller outside diameter portion 36b of the annular seat 36 is fitted in a hole formed in the front wall side of the box 11 so that a circumferential groove 36d formed in the smaller outside diameter portion 36b is exposed to the exterior of the box 11. Then, a stop ring 37 is fitted in the circumferential groove 36d to retain the front-side annular seat 36.
  • the nozzle can retreat to the nozzle holding box 11 side while sliding on the annular seats 34 and 36 against the biasing force of the coil spring 35. Upon release of the pushing, the nozzle is projected by the biasing force of the coil spring 35.

Then, as shown in Fig. 11, the pressurized air thus introduced is stored in the concave portion 32b of the restriction cylinder 32, passes through the plural vent holes 32d and is jetted to the divergent, jet hole 31c. In this case, the inclination of the jet hole 31c causes the jet to form a rotating air current, which is jetted from the jet hole 31c of the support cylinder.
