Abstract: A device for making patches, especially of wood, and for patching resin galls on pieces of wood, comprising a rotatably drivable milling tool, which is rotatably driveable by means of a first driving unit and is held on a supporting frame. Also disposed on the supporting frame is a clamping device, which is rotatable about a rotational axis. A remnant of the workpiece to be patched can be clamped in this clamping device and, by means of rotation about the rotational axis, can be led past the milling tool during which the lateral surface of the remnant is milled. Afterwards the clamping device can be lifted, the remnant being again led past the milling tool, the lateral surface being milled. Afterwards the patch made in this way can be detached.
