Method for machining conical wooden workpieces, device for carrying out such a method and planing machine with such a device

A method for machining a conical wooden workpiece (1), the conical wooden workpiece (1) having long sides (2, 3) lying at an angle to one another and running curved over their length, the method comprising:

• planing a first long side (2) of the long sides (2,3) with a first planing tool (29) along a first curvature of the first long side (2);
• and
• planing an opposite second long side (3) of the long sides (2,3) with a second planing tool (34) along the first curvature of the first long side (2) superimposed with a desired conicity;
• and
• adjusting the second planing tool (34) relative to the first planing tool (29) transversely to a transport direction (13) of the conical wooden workpiece (1) during planing.

A device, comprising:

• two planing tools (29, 34) for machining long sides (2, 3) of a wooden workpiece (1),
• wherein each of the two planing tools (29, 34) sits on a slider (19, 20), and both sliders (19, 20) can be adjusted transversely to a transport direction (13) of the wooden workpiece (1),
• wherein the sliders (19, 20) are coupled by a drive unit (23) and can be displaced relative to each other in a controlled manner by the drive unit (23), and
• wherein the device is configured to perform the following steps:
• planing a first long side (2) of the long sides (2,3) with a first planing tool (29) of the two planing tools (29, 34) along a first curvature of the first long side (2);
• and
• planing an opposite second long side (3) of the long sides (2,3) with a second planing tool (34) of the two planing tools (29, 34) along the first curvature of the first long side (2) superimposed with a desired conicity;
• and
• adjusting the second planing tool (34) relative to the first planing tool (29) transversely to the transport direction (13) of the wooden workpiece (1) during planing.
