ABSTRACT:
A woodworking machine for cutting tenons and mortises in woods, especially window woods, and comprising at least one tenoning-and-mortising unit and at least one lengthwise profiling unit, where a length-cutting device and a roller table are associated with the tenoning-and-mortising unit, where further a transverse conveyor is provided to move the window wood into an operational position wherein the second end of the window wood shall be provided with tenon and mortise and also comprising a transfer system to transfer the window wood equipped at both ends with tenons and mortises to the lengthwise profiling equipment, said machine being designed in such a manner that its manufacture is economical and its construction is compact.
For that purpose the invention provides a single tenoning-and-mortising unit which together with its associated length-cutting device, its bearing, its hood and the like can be entirely lowered below the surfaces of the work and roller table, where the tenoning-and-mortising unit below the work and roller table can be moved from a first position wherein the first end of the window wood is processed into a second position where the second end is processed, this window wood in order to be processed at its second end being moved oppositely to the previous direction of advance along the offset tenoning-and-mortising unit of which the processing wides face each other in the two said positions, the window wood being cut to length following the processing of the first end and then being displaced.
