PURPOSE:To obtain the titled spun yarns of stabilized quality without the limitation by the properties of a core yarn, by laying a roving of the core component on the central part of a sliver for forming the outer layer, bringing the outer layer side of the sliver into the full contact with a guide, twisting one end of the sliver in the width direction delayed a given angle, and wrapping the core yarn in the outer layer. CONSTITUTION:A sliver (B) forming the outer layer is passed through a guide (G1), held by back rollers 1 and l' and fed to the bottom of a two-stage guide (G2). A roving or sliver (A) constituting a core yarn part is simultaneously fed to the top of the two-stage guide (G2), laid on the central part of the sliver (B), passed through a collector (G3) and held by front rollers 3 and 3'. The outer layer of the sliver (B) is then brought into the full contact with a guide (G4) at an angle (beta) to the vertical face parallel to the shafts of the front rollers 3 and 3', and one end of the sliver (A) in the width direction is delayed at least 180 deg.C in the twisting direction compared with the other end and twisted to wrap the core yarn part. The twisted sliver is then passed through a flyer 4 and wound aroung a roving wooden bobbin 5. |
