FIELD: machine building.SUBSTANCE: device to produce pneumatically twisted carbon fibre comprises a body with a shaft of air supply, at the bottom of which at the angle 45±10° there is a guide nozzle of carbon fibre supply, and at the end of the air shaft with the help of a yoke there is a corrugate sleeve fixed, the length of which exceeds its distance from the cut of the guide nozzle more than twice, the cut of which is made at the angle ±15° to the longitudinal axis of the shaft, besides, height of the guide nozzle inside the shaft makes 0.1-03 of the shaft diameter. On the guide nozzle there are feed rollers and a rotary knife.EFFECT: increased efficiency of a device for preparation of carbon fibre and intensity of its pneumatic twisting.4 dwg |
