Title:
THREAD PRODUCTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/011770
Kind Code:
A1
Abstract:
A thread production device (1) produces a carbon nanotube (CNT) thread (Y) from a CNT fiber group (F) while running same, the device being provided with: a winding drive mechanism (50) for rotating a winding shaft (53), on which a winding tube (T) is attached, about the winding central line of the winding shaft (53); a twisting drive mechanism (60) for rotating the winding tube (T) about a rotation central line which is a predetermined line (L) along the running path of the CNT fiber group (F) and the CNT thread (Y) guided to the winding tube (T) by means of a guide part (63); and a traverse drive mechanism (70) for moving the winding tube (T) back and forth relative to the guide part (63) along the winding central line of the winding shaft (53). A winding drive motor (51), a twisting drive motor (61) and a traverse drive motor (71) are secured to a frame (6a) which supports the winding drive mechanism (50), the twisting drive mechanism (60) and the traverse drive mechanism (70).
