Conventionally, when manufacturing scrim cloth bonded prepreg, as shown in Figure 1, reinforcing fibers 1
are fed parallel to each other in sheet form from rolls 2, and on the other hand, a lower resin-carrying sheet 3 is fed from roll 4, so that the resin surface of the lower resin-carrying sheet 3 is first superimposed on the lower surface of the reinforcing fibers 1.

ール１２，１３で加熱、押圧していた。 Next, the upper resin-supporting sheet 5 is supplied from the roll 6, and the resin surface of the upper resin-supporting sheet 5 is superimposed on the upper surface of the reinforcing fibers 1, resulting in a superimposed body 7.
is supplied to heating rolls 8, 8, heated and pressurized to transfer and impregnate the reinforcing fibers 1 with resin to produce a unidirectional prepreg 9, and from this prepreg 9, a sheet forming the upper resin supporting sheet 5 is produced. The sheet 5' was peeled off and wound onto a roll 10, and the scrim cloth 11 of the roll 14 was superimposed on the surface from which this sheet 5' was peeled, and then heated and pressed with scrim cloth laminating rolls 12 and 13. .
