<p>PURPOSE: To achieve an increase in strength, environment protection and a reduction in a manufacturing cost by constituting a fiber plate of a mat comprising binder-added pulp and reinforcing sheet bodies, whose tensile strength is larger than that of mats, which are laminated on the above described mat. CONSTITUTION: For a fiber plate M9, a binder B is added into fiber-dissolved pulp, wherein a small piece of a fiber obtained by cutting waste paper into a specified size is dissolved, the pulp is compressed and formed into a mat shape, and a mat M5 is obtained. Reinforcing sheets S, whose tensile strength is larger than that of the mat M5, are laminated. The binder B is sprayed, compression is performed under the heated state and cutting is performed. Thus, the fiber plate M9 is obtained. The mat M5 is made to form the unitary body under the state, wherein the mat M5 is held between a pair of the reinforcing sheet bodies S by the adhesion and solidification of the binder B, which is uniformly mixed in the fiber-dissolved pulp, the binder B, which is applied on the surface of the mat M5, and the binder B, which is sprayed on the surface of the reinforcing sheet bodies S. The solidified mat M5 is covered with the reinforcing sheet bodies 3 having a large tensile strength. Therefore, the strength of the surface of the fiber plate M9 becomes especially large.</p> |
