Abstract: A tenoner provided with two driven milling cutters positioned opposite each other on both sides of a traveling carrier for a workpiece. Each cutter is carried in a carriage mounted in a supporting element which comprises a base displaceable on the frame in two mutually perpendicular directions. The carriage is tiltable around two mutually perpendicular axes for setting the location and angular position of a tenon.These axes intersect each other at an imaginary point coinciding with the root of the tenon, which is i.e. the center of the common attachment plane of tenon and workpiece. The cutters each make a stepwise revolution and a rectilinear reciprocating motion around the root in producing a tenon. Because of this arrangement, the angular setting of the cutter can be quickly adjusted.

Abstract: A machine for milling a tenon to the straight end of wooden workpieces, like a strip or a beam, wherein two wooden workpieces disposed upon two sledges or tables moving in transverse position to and fro in between abutments, are milled one after another in one single pass through the machine by means of a driven cutter carried upon a support structure which periodically performs a revolving movement over 180.degree., each time said cutter reaches a side face of the tenon to be produced, said pivotal movement being initiated by a signal from a pulse transmitter cooperating with the sledge or table such that said signal is dependent upon the position of the relative sledge, and so that said cutter always cuts toward the tenon being cut.
