    摘要： A production method of a long member including a large number of carbon nanotubes includes the steps of: (1) drawing the carbon nanotubes gradually from a first array to obtain a first web 10a; (2) bringing the first web 10a partially into contact with a first holder 12a to hold the first web 10a on the first holder 12a; (3) drawing the carbon nanotubes gradually from a second array to obtain a second web 10b; (4) bringing the second web 10b partially into contact with a second holder 12b to hold the second web 10b on the second holder 12b; and (5) placing a portion of the first web 10a and a portion of the second web 10b on each other to form a joint, the portions of the first and second webs 10a and 10b being in the vicinity of the first and second holders 12a and 12b, respectively, and being placed on each other such that width directions of the first and second webs 10a and 10b are substantially the same.

    摘要： A yarn producing apparatus is provided that produces carbon nanotube yarn at high speed. The yarn producing apparatus 1 includes a yarn producing unit 5 that aggregates running carbon nanotube fibers F. The yarn producing unit 5 includes a nozzle body 10, a first nozzle 20 provided in the nozzle body 10 to generate a first swirl flow, with compressed air, in a direction orthogonal to the direction of the carbon nanotube fibers F running, and a second nozzle 30 provided in the nozzle body 10 to generate a second swirl flow, with compressed air, in a direction orthogonal to the direction of the carbon nanotube fibers F running and opposite to the direction of the first swirl flow. The first nozzle 20 and the second nozzle 30 are provided at positions different in the direction of the carbon nanotube fibers F running in the nozzle body 10.

    摘要： A yarn producing apparatus 1 is an apparatus for producing carbon nanotube (CNT) yarn Y by aggregating CNT fibers F and includes a front roller 3 configured to continuously draw the CNT fibers F from at least one CNT forming substrate S, a yarn producing unit 4 configured to aggregate the CNT fibers F drawn by the front roller 3, and a status monitor (yarn thickness detecting sensor 6) configured to monitor a state of the CNT fibers F drawn from the CNT forming substrate S, or the CNT yarn Y
