    摘要： A mitered corner for a strip of molding in which the edges of the said corner closely abut each other. A strip of L-shaped molding, as is used for example in covering the edge of a table or counter top, is notched so that it can be bent at the corners of said top, and the notched faces are undercut to cause said edges to closely abut each other at their upper surfaces. In the method of making said mitered corner, the normally vertical leg of the molding is held in a vertical plane, with the other leg projecting therefrom at an angle of about 120*. The miter cut is then made in said other leg in the vertical direction to yield a notch which is effectively undercut when the legs of the molding are bent from their included angle of 120* to an included angle of 90*.
