<P>PROBLEM TO BE SOLVED: To provide a method and a device for uniformly impregnating reinforcing fiber with a resin with time or uniformly in the cross-sectional direction with the use of the roll transfer method capable of producing a reinforcing fiber prepreg at a low cost. <P>SOLUTION: In impregnating reinforcing fiber with a resin by the roll transfer which brings an impregnation roll 3 having a predetermined thickness of a resin layer formed on its surface into contact with reinforcing fiber 5 to transfer the resin to the reinforcing fiber, a predetermined range of the resin on the impregnation roll at the sides of the reinforcing fiber is scraped and supplied to the surface of the reinforcing fiber not in contact with the impregnation roll. As the means to scrape the predetermined range of the resin to be supplied to the surface of the reinforcing fiber not in contact with the impregnation roll, a resin supply means 8 in which the gap to the reinforcing fiber is gradually narrowed is provided. <P>COPYRIGHT: (C)2013,JPO&INPIT |
