Abstract of the Disclosure Apparatus is described for continuously pro- ducing finger jointed lumber from individual elongated boards. Each board includes opposed end faces with elon- gated parallel fingers that will mate with complementary fingers of a following board to form end-jointed lumber. A reciprocating ram engages one end of successive indi- vidual boards, pushing the board longitudinally along a path to a confining box. The ram retracts to engage a successive board along its end face to push it longitudi- nally into engagement with the board held by the confin- ing box. The fingers of the engaging board ends mate within the confining box and are pressed together to com- plete a joint. The ram includes a ram face that is com- plementary to the finger configuration of the board ends to mate intimately with the board end. The ram face may be heated to apply heat to the successive board ends for glue curing purposes. The successively engaged boards are pressed firmly together to complete the joint by op- eration of the ram or by auxiliary moving clamp assem- blies along the framework of the apparatus.
