PROBLEM TO BE SOLVED: To improve surface quality including cracks and smoothness by installing a device for preventing the inversion of a carbon fiber bundle between a part in which numbers of carbon fibers are arranged at prescribed intervals and a part to be impregnated with a resin. SOLUTION: A winding package 1 of a carbon fiber bundle Y, the carbon fiber bundle Y is arranged by a draw free rotation roller 2. Next, the bundle Y is arranged through a separation comb 3 and supplied to an inversion preventing device 5. A heating means 4 is installed upstream from the device 5, and the bundle Y is heated. After that, the bundle Y is passed through the device 5 consisting of a roller having projections on its surface and a free rotation roller 6 to prevent inversion. Subsequently, then bundle Y is passed through an opening apparatus 7 and introduced into an impregnation apparatus 11. The opening apparatus 7 is constituted so that the carbon fiber bundle Y supplied through an introduction free rotation roller 7a passes on a group of rollers while being bent at a prescribed angle to be opened and discharged through an opening apparatus exit free rotation roller 7d. |
