Abstract
A method of mending a veneer sheet having a defective portions is provided. An imcomplete veneer sheet and a sheet of mending material is laid one on top of the other. They are cut through by a single stroke of a annular cutting tool such that the defective portion of the veneer sheet is cut off whereas a plug having a same size and shape as the cut-off defective portion is cut out. They are retained in the annular cutting tool until the plug is shifted into a plane in which the veneer sheet extends. At the same time, the cut-off defective portion is removed from the veneer sheet. Then, when the cutting tool is removed from the sheets, a mended veneer sheet results. Another method is also provided. A plurality of plugs are cut out from a sheet of mending material by repeatedly cutting through it by a single annular cutting tool. The cut-out plugs are retained in the annular tool. Then, an incomplete veneer sheet is cut through by the tool to cut off a defective portion from the veneer sheet while the plugs retained in the tool pushed farther into it. However, a plug in contact with the cut-off defective portion is pushed toward the plane in which the veneer sheet extends. As a result, the defective portion is routed out. When the annular cutting tool is removed from the sheet, the mended veneer sheet results. This can be repeated until the plugs run out.
