<p>To provide a method and device with which Alternate Twisted Yarn can be produced simply and inexpensively. An alternate twisted yarn is produced by alternately repeating with a neutral and tilt switching method and twisting yarn (1) in the reverse direction onboth sides of pulley (2) driven by yarn (1) that is inserted between the flanges of pulley (2), so that the yarn passage is bent or flexed. Shaft (3) of this pulley (2) is inclined to the yarn (1) passage plane to bring yarn (1) into contact with the flange section (2a's) internal surface of pulley (2), and in the neutral position under which yarn (1) is not twisted on both sides of pulley (2), with shaft (3) of pulley (2) being made perpendicular to the yarn (1) yarn passage plane to cut off its contact to the pulley (2) flange section (2a's) internal surface.</p> |
