Abstract
A yarn producing apparatus produces 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. The aggregating unit includes an adjusting mechanism that adjusts the aggregation state of the CNT fibers.
Claims20
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:
- an aggregator that aggregates the carbon nanotube fibers such that the carbon nanotube fibers are in contact with each other;
- and
- a twister that twists the carbon nanotube fibers aggregated by the aggregator;
- wherein
- the aggregator includes a first plate provided with a first notch and a second plate provided with a second notch, the first notch and the second notch together defining a through hole;
- the aggregator includes a biasing member that adjusts an aggregation state of the carbon nanotube fibers by adjusting a positional relation between the first plate and the second plate to adjust an opening area of the through hole.
