  • Apparatus for wet manufacturing fiber reinforced thermoplastic resin sheet
    Patent number: 5888352
    Abstract: The present invention provides an apparatus for wet manufacturing a fiber reinforced thermoplastic resin sheet, having a manifold capable of uniformly distributing the solid concentrations without being affected by inertia force caused by the difference in shape between solids. The invention further provides an apparatus for wet manufacturing a fiber reinforced resin sheet having a buffer inlet or reservoir headbox capable of permitting inhibition of variations of the unit weight distribution under the effect of the dynamic pressure of the raw material dispersing liquid and the resultant fluctuations.
