A machine for washing scraps of fibrous material where the fibrous material has been impregnated with resin, and the machine extracts the resin via the use of appropriate solvents. The machine includes a closed, hollow container having an inlet and an outlet. The container encloses at least one conveyor belt. At least one overhead spraying device is situated over the conveyor belt. The overhead spraying device delivers solvent which is contained in at least one solvent tank. A drying device is installed at the finishing end of the conveyor belt so as to be upstream of the outlet of the container. A process is also provided for washing scraps of fibrous material impregnated with resin. The process includes the steps of feeding the scraps into a closed, hollow container, washing the scraps with at least one solvent spray, and drying the washed scraps inside of the container.
