PURPOSE:To provide possibility of changing the amount of yarn supply in an any and great scale, by controlling the injection direction and the rate of injection of a compressed fluid at discretion, and by changing the number of revolutions of a feed roller. CONSTITUTION:Compressed fluid is led from a compressed fluid generator 7 to a nozzle 6 and injected to an impeller 5 to cause rotation of a yarn feed roller 4 mounted coaxially with said impeller 5 solidly as in a single piece, and then the yarn 2 is supplied. At this time, the orientation of said nozzle 6 is controlled at discretion by a link mechanism in compliance with a command given by a random signal generator 8, so as to change the injecting direction of compressed fluid and also the number of revolutions of feed roller 4. Thus the amount of yarn supply can be changed in an any and great scale. |
