In the insizing apparatus 1, before the wood M is carried in, the distance between the pair of upper and lower rotary blades 6 and 6 and the left and right rotary blades 7 and 7 is determined according to the thickness and width of the wood. The rotary blades 6 and 6 and the rotary blades 7 and 7 are rotated as appropriate.
[0063]
When the wood M is carried into the insizing processing apparatus 1, the wood M is inserted between the rotary blades 6 and 6 and between the rotary blades 7 and 7, thereby forming the outer peripheral portions of the rotary blades 6 and 7. The pushing blades 8 that have been pushed in sequentially push the surface of the wood M, and the pushed-in pushing blades 8 are sequentially pulled out.
