WIPO Patent Application WO/2002/101129

Kind Code:

A1

Abstract:

A production device and production method for carbon fibers, capable of a continuous operation and lowering costs with an operability in a firing process enhanced by positively providing connection portions having a simple mechanism and a high process throughput. The production device comprises a pair of yarn gripping devices (12) that overlay precursor fiber yarns to be connected one upon another and grip the overlaid ends, and a fluid treating unit provided between the pair of gripping devices (12), for jetting a plurality of rows of fluid along a yarn length direction to bind the yarns. A plurality of discontinuous thread handling areas (11b) of the precursor fiber yarns in fluid jet areas, having fluid jet holes (11a), of the fluid treating unit are disposed at specified intervals (S).
