  • Patent number: 4164439
    Abstract: A process and apparatus for the continuous production of fiber reinforced plastic grating articles is provided wherein continuous strands of fibers are coated with a thermosetting plastic resin material and woven into a grate pattern defined by upper and lower molding teeth arranged on continuous upper and lower molding tracks. The molding tracks rotate and cause the molding teeth to mesh, forming a molding cavity, wherein heat is applied to set the plastic resin. The fiber reinforced plastic grating articles formed by this process and apparatus have a unique cross-sectional configuration and arrangement of fibers providing for increased strength and reduced resin usage.
