Abstract

An apparatus for producing a fiber reinforced synthetic resin provides a fiber feed passage through an outer chamber to which the synthetic resin for feed. A feed passage for the fiber extends concentrically in this chamber and has a tubular formation of a diameter less than that of a cleaning piston which is displaceable in the annular space between this tubular formation and the inner wall of the chamber.
