ABSTRACT:
A system for cutting a profile along a linear edge of a wooden workpiece utilizes two spaced-apart rotatable cutting tools which are mounted for rotation in opposite rotational directions and a support surface for supporting the workpiece for movement along each of the two cutting tools. By positioning the workpiece upon the support surface so that the linear edge thereof extends between the two cutting tools, the workpiece can be moved into cutting engagement with a first of the cutting tools and subsequently into cutting engagement with the second of the cutting tools. By subsequently reversing the movement of the workpiece along the first cutting tool before the cutting edges thereof exit a trailing (side) edge of the workpiece, the likelihood that the workpiece will be damaged from the profile-forming process is reduced.
