Abstract
A yarn producing apparatus is an apparatus for producing CNT (carbon nanotube) yarn from CNT fibers while causing the CNT fibers to run. The yarn producing apparatus includes an aggregating unit that aggregates the CNT fibers, and a twisting and winding device that twists the CNT fibers aggregated by the aggregating unit.
Claims19
A yarn producing apparatus for producing carbon nanotube yarn from carbon nanotube fibers while causing the carbon nanotube fibers to run, the yarn producing apparatus comprising:
- a preliminary aggregator that aggregates the carbon nanotube fibers while exerting a resistive force on the carbon nanotube fibers against a direction in which the carbon nanotube fibers run;
- a twister that twists the carbon nanotube fibers aggregated by the preliminary aggregator;
- and
- a tensioner that acts on the carbon nanotube fibers running between the preliminary aggregator and the twister and applies tension to the carbon nanotube fibers to be twisted by the twister.
