Abstract:
1. An embedment device for use in the production of cementitious panels wherein a hydraulic cement slurry is transported on a moving carrier relative to a support frame for the moving carrier, and chopped fibers are deposited upon the slurry, said device comprising; a wire grid structure having two side wall frames; a support structure; the wire grid structure with two side wall frames is mounted to the support structure, wherein the support structure is mounted on the support frame for the moving carrier so the wire grid structure is mounted transversely to the direction of travel of the moving carrier and slurry, and a means on the support structure for moving the wire grid structure up and down in a reciprocating motion for contact with the fiber and slurry layer on the carrier to penetrate the layer from a top surface of the slurry to a bottom surface of the slurry on the moveable carrier to press the fiber into the slurry; wherein the grid structure is attached to the side wall frames and comprises a number of cross members which intersect in a perpendicular angle to form a rectangular grid with rectangular openings, said number of cross members comprising a first plurality of cross members aligned in a first direction and extending within a perimeter of the grid structure as well as a second plurality of cross members aligned perpendicular to the first direction and extending within a perimeter of the grid structure.
