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. Owing to the small dimensions and the light weight of this device for making patches, it can be used by the craftsman at the work location, it being then possible to make the patch directly from a remnant of the piece of wood to be patched, ensuring that the patch and the piece of wood to be patched correspond in quality.
