Abstract
An apparatus for shaping a wooden workpiece according to a template configuration has a carriage displaceable on a track parallel to a guide edge of a template clamped on a table to one side of the track. A workpiece is clamped to a table to the opposite side of the track. A slide is displaceable on the carriage transverse to the track and carries on one end a roller engaging the guide edge of the template and on its other end a driven tool for cutting the shape of the template into the workpiece. The slide is urged toward the workpiece so that virtually no lateral force is exerted against the workpiece, the guide edge acting as a stop positively determining the transverse position of the slide. Another template can support a second feeler roller which is connected via a chain or the like to the tool to raise and lower this tool according to the guide edge on the second template for two-sided cutting of the workpiece.
