Abstract
A fiber reinforced inorganic hardened body is manufactured from raw material including of a mixture of reinforcing fiber such as bamboo fiber, water-hardening inorganic binder and water by a manufacturing apparatus for stirring and mixing such raw material and forming it into a mat configuration laminated with the thin layers of fine fibers on the both front and rear sides of the thick layer of the normal raw material. The fine fiber material adhered with the water-hardening binder is partially separated from the main raw material at both the material supply side and material discharge side of a pin-type roll set. The portion of the fine fiber separated from the main raw material is first supplied to the upstream side of of the forming conveyor to form a first layer of fine fiber. The remaining raw material is supplied onto this first layer of fine fiber on the forming conveyor to form a second layer of main raw material, and the other part of the fine fiber separated from the raw material at the material supply side is dropped onto the second main layer of the raw material to form a third layer of fine fiber, to thereby form a mat of raw material of the first and third layers of f…
