Jointer

A jointer or in some configurations, a jointer-planer is a woodworking machine used to produce a flat surface along a board's length. As a jointer, the machine operates on the narrow edge of boards, preparing them for use in a butt joint often used to glue boards into panels. A planer-jointer setup has the width that enables smoothing ('surface planing') and leveling the faces (widths) of boards small enough to fit the width of the tables and blades.
