Machine and method for machining, in particular planing, conical workpieces of wood, plastics, and the like

A method for machining boards of wood or plastics, the method comprising:

• feeding boards in a transport direction through a machine comprising two or more rotatably driven tools, wherein a length direction of the boards extends in the transport direction and the boards are transported horizontally on a flat bottom side thereof through the machine;
• machining boards on at least one of a right longitudinal side and a left longitudinal side of the boards extending in the transport direction of the boards and adjoining the flat bottom side by:
• a) measuring the boards prior to or during feeding at least in regard to a conicity to be machined;
• b) producing at the boards at least one form-fit element configured to interact with at least one counter form-fit element during feeding of the boards and linearly guiding the boards in the transport direction through the machine;
• c) continuously adjusting at least one of the two or more rotatably driven tools in relation to at least one of the right longitudinal side and the left longitudinal side of the boards transverse to the transport direction during feeding of the boards through the two or more rotatably driven tools to machine at least one of the right longitudinal side and the left longitudinal side of the boards to produce at least one conically tapering straight longitudinal side based on the conicity measured in the step a);
• d) joining two of the boards to each other by placing the respective at least one conically tapering straight longitudinal side against each other to form a board pair comprising approximately parallel longitudinal sides and an approximately rectangular contour and, prior to joining, rotating a first one of the two boards about an axis perpendicular to the bottom side of the first board.

• d) transversely cutting a respective board into two board parts about an axis transverse to the length direction of the respective board so that each of the two board parts comprises a conically tapering section of the at least one conically tapering straight longitudinal side;
• e) rotating one of the board parts by 180° about an axis perpendicular to the bottom side and joining the two board parts by placing the conically tapering sections against each other to form a board pair comprising approximately parallel longitudinal sides and an approximately rectangular contour.
