  • Method and apparatus for producing sheet molding compound
    Patent number: 4219524
    Abstract: The invention relates to apparatus and method for forming a sheet molding compound. The sheet molding compound is linearly advanced. A moveable upper surface formed by a belt passing around a series of driven rollers is adapted to contact the upper surface of the sheet molding compound. The belt is held in biased relationship to the sheet molding compound. In one arrangement of the invention, the sheet molding compound is caused to undulate vertically while retained in compression to induce one form of shear effect. In still another embodiment, as the molding compound is passed in vertically undulating fashion between compressing mesh belts, one of the belts is driven at a fixed rate, while the opposite is driven at rates oscillating above and below the fixed rate.
