To provide an accumulator for a filament body capable of increasing the feed speed of the filament body without causing the fluctuation of tension and ensuring the tension resistance of a device even to the tension increase of the filament body caused by high speed feed, without depending on the increase of mechanical strength.
This accumulator 21 for the filament body accumulates the filament body 23 by extending the fed filament body 23 between a fixed pulley 25 and a moving pulley 27 arranged on a feed line of the filament body 23. A first moving pulley 27a adjusted in the center distance to the fixed pulley 25 in order to mainly adjust tension applied to the fed filament body 23, and a second moving pulley 27b adjusted in the center distance to the fixed pulley 25 in order to mainly adjust the feed speed of the filament body 23, are equipped as the moving pulley 27. The feed speed and tension of the filament body 23 can thereby be individually adjusted.
