    摘要： Scarf faces 92a, 92b are machined at a heeling angle θ 2 on a veneer 90 by adjusting the heeling angle θ 2 for a desired camber h using the following Equation (1): h = R 2 • sin θ 2 − sin 2 θ 2 • R 2 − t 2 ( 1 + i 2 ) 4
    With the configuration, double cutting of the veneer 90 by a circular saw 20 can be effectively prevented. Since the camber h is set desirably, the risk can be reduced that the scarf faces 92a, 92b only partially join each other, and a space can be secured to retain an adhesive Ad between arc concavities 91, 91. Thus, when the veneers 90 are joined together at the scarf faces 92a, 92b, the adhesive Ad is unlikely to seep out onto the surfaces of the veneers 90. As a result, the scarf faces 92a, 92b can be properly joined together.
