ABSTRACT:
A machine and method for cutting notches with rounded inner corners in wood pallets. The completed notches are made in one pass through the machine as the pallet passes over three successive stages of cutting. The first stage makes six vertical cuts for each notch, the inner four cuts to the depth of the notch and the outer cuts decreased in depth by the radius of the rounded corner and the outer cut being laterally separated from the adjacent deeper cut by a distance also equal to the radius of the rounded corner. The second stage, with a horizontal cut removes the wood between the inner four cuts and the third stage cuts out the rounded corner with a horizontally positioned radius cutter.
