Method for producing structures or contours on a workpiece, and moulder

A moulder for performing a method for producing a structure or contour in a workpiece of wood or plastic material, in which in a moulder with at least one rotatably driven tool the structure or contour is produced on the workpiece by workpiece material removal, the method comprising defining tool positions of a tool along a length of the workpiece for generating a structure or contour, the tool positions being defined as a function of first data of the workpiece and second data of the tool;

• transmitting the first and second data to a machine controller of the moulder;
• executing a CNC (computer numerical control) program based on the first and second data during passage of the workpiece through the moulder;
• detecting workpiece positions upon passage of the workpiece through the moulder;
• and adjusting the tool into required positions by CNC (computer numerical control) drives as a function of the workpiece positions;
• the moulder comprising:
• a machine controller;
• at least one transport path for the workpieces along which the workpieces are transported in a feeding direction through the moulder for machining;
• rotatably driven tools including at least one structure-producing tool configured to produce a structure or contour in the workpiece;
• a measuring element arranged in front of said at least one structure-producing tool and a measuring element arranged behind said at least one structure-producing tool, wherein the measuring elements are configured to detect a workpiece position in the moulder;
• wherein the measuring elements are connected to the machine controller and supply signals, describing a feeding travel of the workpiece through the moulder, to the machine controller;
• wherein the machine controller, in accordance with the signals of the measuring elements, adjusts said at least one structure-producing tool into tool positions required for machining;
• wherein the measuring elements each are embodied as a measuring roller resting on the workpiece as the workpiece is fed through the moulder.
