BED PLATE FOR GAME MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a bed plate for a game machine by which productivity is improved by dispensing with work for straightening warpage. SOLUTION: The bed plate C for the game machine is obtained by sticking a surface layer B consisting of a timber veneer to at least one of the surfaces of a fiber layer A produced by sticking kenaf fibers obtained by splitting the kenaf with a thermosetting adhesive. The kenaf fibers having an average length of 10 to 200 mm and an average diameter of 10 to 300μm are used. By impregnating a fiber mat obtained by aggregating the kenaf fibers with the thermosetting adhesive, the density of the fiber layer A is made to be 600 to 900 kg/m3. The fiber layer A whose dimensional change due to temperature variation is smaller than that of the veneer is used. COPYRIGHT: (C)2005,JPO&NCIPI
