PURPOSE:To improve conveying property and a molding property, by forming a mat molding body wherein wooden fiber including a synthetic resin is deposited, into a concave and convex plate shape wherein concave bent parts and convex bent parts are alternately arranged, and providing a semihardened state on the upper surface or both upper and back surfaces of the plate. CONSTITUTION:Wooden fiber (a) is sent by air and inputted in a hopper 1. In the hopper 1, 5-30pts.wt. of powder (b) of thermosetting synthetic resin such as phenol resin and urea resin are inputted with respect to 100pts.wt. of the wooden fiber (a). The wooden fiber (a) and the resin powder (b) are mixed and a raw material (c) is obtained. Said raw material (c) is sprayed and deposited on a conveying body 2. Then the material is compressed by compressing rollers 3 of network rollers, and a mat molding body (d) is obtained through squeezing rollers 4. Then the molding body (d) is thermally compressed by heating rollers 5, which are a pair of upper and lower embossing rollers. A concave bent parts (f) and convex bent parts (g) are alternately arranged, and a concave and convex plate shaped molding mat (e), whose upper and back surfaces are under the semihardened state, is obtained. |
