Abstract

PURPOSE:A drafting device in which a middle top roller that positively revolves under synchronization with a middle bottom roller is fitted between the back roller and the front roller, thus removing the fluctuation in drafting. CONSTITUTION:Sliver S is drafted with back roller 2, middle roller 4 and front roller 9, twisted with the first nozzle 10 and the second nozzle 11 and the resultant spun yarn Y is wound up on bobbin 15 wherein a middle top roller 7 that positively revolves under the synchronization with a middle bottom roller 5 in the middle roller 4 is equipped. Thus, slipping between upper and lower aprons 8 and 6 is prevented and flying fibers are surely sent to cause reduced yarn unevenness and produce spun yarns with uniform qualities.
