UNIVERSAL METHOD TO UNTWIST, UNRAVEL AND OPEN UP A TEXTILE YARN |
摘要 |
The method involves the use of two nozzles (5 and 6) which alternatively blow air jets against a yarn in the central portion of a channel (1), these nozzles being symmetrically placed in relation to a plane containing the channel axis. The jets blowing frequency is of several hundreds of Hz. A deflector (3) in the bottom of channel (1) can deviate the beating thread sidewise and consequently impart thereto alternate twisting and untwisting motion in order to unravel the thread.
