Abstract
Disclosed is a production system (1) for a carbon fiber thread (Z) by continuously subjecting a carbon fiber thread precursor (X) having a jointed portion (a) connecting respective ends of two carbon fiber thread precursors (X) to heat treatment, which contains an oxidization oven (10) for subjecting the carbon fiber thread precursor (X) to an oxidization treatment, a carbonization furnace (12) for subjecting a thus obtained oxidized fiber thread to a carbonization treatment, a winder (18) for winding the carbon fiber thread (Z) around a winding bobbin, a detection means (24) for detecting the jointed portion (a), a positional information-acquisition means (26) for acquiring positional information of the jointed portion (a), a control means (28) for controlling the winder (18) in such a way that a carbon fiber thread including the jointed portion (a) and a carbon fiber thread not including the jointed portion (a) are separately wound up around different winding bobbins based on the positional information. Also disclosed is a production method for a carbon fiber thread by use of the production system (1).
