Pneumatic threader for twisting apparatus |
摘要 |
A pneumatic threader for a twisting apparatus has a nozzle formed with a counterbore so that the nozzle can be fitted over the end of the inlet tube of the twisting apparatus. In addition this nozzle is formed with a slot opening toward the tube and extending beyond the counterbore so that a filament engaged in this slot can freely pass into the tube. The slot may extend helically up around the tube so that automatic clamping of the filament is effected when it reaches the end of the helix. It is also possible to form the slot parallel to the air passage in the nozzle and to provide a clamping member for holding the filament end in the upper portion of this slot. To this end a lost-motion coupling may be provided between the valve-operating trigger of the pneumatic threading apparatus and the operating lever for opening of the clamp shortly after air flow has been started.
