A yarn producing apparatus includes front rollers movable while carbon nanotube (CNT) fibers are running and aggregates the CNT fibers. Each of the front rollers includes a groove provided on an outer circumference thereof to aggregate 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 aggregating unit that is movable with the carbon nanotube fibers running and aggregates the carbon nanotube fibers into a bundle;
- and
- a support that supports a carbon nanotube assembly from which the carbon nanotube fibers are drawn;
- wherein
- the aggregating unit includes a groove provided at a portion thereof to aggregate the carbon nanotube fibers;
- and
- the aggregating unit is located such that the carbon nanotube fibers first contact the aggregating unit in a direction of the carbon nanotube fibers running after the carbon nanotube fibers are drawn from the carbon nanotube assembly supported on the support.
