Abstract: A material extrusion and patterning machine for a workpiece having an irregularly curved edge and a method of manufacturing the same. In one embodiment, the machine includes: (1) a frame, (2) a fixture coupled to the frame for rotation relative thereto and having a clamp adapted to hold the workpiece, (3) an extrusion head, coupled to the frame for translation relative thereto and adapted to move relative to the axis of rotation to follow the edge and (4) a mold mount, coupled to the frame for translation relative thereto and adapted to move relative to the axis of rotation to follow the edge, the extrusion head and mold mount cooperating to deposit the material on the edge and allow a mount to place a pattern on the material as the workpiece rotates relative to the frame.

Abstract: The present invention provides a dovetailing and assembly machine that forms a groove on the planar surface of a first workpiece and inserts a preformed tenon on one end of a second workpiece into the groove. In one embodiment the groove is dovetail-shaped. The present invention also provides for a method to manufacture a dovetailing and assembly machine. In one embodiment the machine comprises: (1) a frame, (2) a jig coupled to the frame and adapted to hold a first workpiece, (3) a router coupled to the frame and adapted to move relative to a planar surface on the first workpiece and to cut a groove thereon, (4) a mount coupled to the frame to hold the tenon in substantial alignment with the groove and (5) a press coupled to the frame adapted to press the tenon into the groove.

Abstract: An embosser and a method of manufacturing the same. In one embodiment, the embosser has a frame, a hammer and an anvil and includes: (1) a ram coupled to the frame and oriented to apply a force in a given direction and (2) force translators, coupled to the ram and the hammer, that reorient the force in a direction substantially normal to a plane of a face of the hammer and limit a cant of the hammer with respect to the anvil.
