PROBLEM TO BE SOLVED: To decide the correctional shape of a non-rectangular construction material and manufacture it at the molding time by compressing numerous wood chips to the specified crossectional shape using a roll molding device and joining a decorative board on the surface of a core part to be delivered continuously. SOLUTION: Plual wood chips 21 as a raw material are impregnated with a binder, then are dried and the dried wood chips 21 are loaded into a supply part 31 successively on a production line 30. Further, these wood chips are pressed between the rollers 35, 35 of a molding machine 33 into a specified correctional shape under compression and the compressed wood chips are heated using a heating device 37 to obtain a binding force between the wood chips 21. In addition, an adhesive is applied to the surface of core parts to be fed as a continuous material using an adhesive appellation device 40. After this process, a decorative board 12 sliced out of a decorative board supply device 45 is held between the rolls 51 of a molding device 50 while stacking the decorative board 12 on the surface of the core part. The joint between the decorative board 12 and the core part surface is secured by heat through their passage in a heating device 57, and this particle board is cut to the specified length as a raw material for a construction material or furniture using a cutter. Thus it is possible to mold the particle board with a variation-rich correctional shape. |
