PURPOSE: To facilitate manufacture of a prepreg which is uniform in resin distribution on both front and rear surfaces by stabilizing viscosity by a method wherein a resin feeder for supplementation of resin varnish a temperature and a viscosity of which are controlled is annexed to a position where the resin is difficult to be circulated and apt to stay since a base material becomes a baffle. CONSTITUTION: A supplementary resin varnish feeder 10 is provided on an upper surface of an impregnation bath 1. Resin varnish 3 a temperature and a viscosity of which are controlled in the same way as for the resin varnish feeder 2 is supplementarily constituted in a part 8 enclosed by a base material 6 on a side in contact with a roll 4 in the bath on the upper surface side of the impregnation bath 1. Since the part 8 is a position where the resin varnish 3 is difficult to be circulated and apt to stay in the impregnation bath 1, a difference in viscosity of the resin varnish 3 is generated between a non-contact side part 9 of the roll 4 in the bath and that position. However, since the resin varnish 3 the temperature and viscosity of which are controlled is compulsorily fed from the supplementary resin feeder 10, stabilization of the viacosity of the resin varnish 3 in the impregnation bath 1 can be achieved. |
