ABSTRACT:
A cutting head for forming finger joints in the ends of successively presented boards moved into engagement therewith, is slidably mounted for vertical reciprocation between two preselected cutting positions. The movement is imparted by a pressure fluid actuator which is cyclically actuated to urge the cutting head alternately into the preselected positions after each cutting operation. The apparatus facilitates shaping consecutive work pieces respectively into left and right hand mating finger joints with a single cutting head, requiring no manual effort or set-up between pieces.
