Abstract

The tool is applied with pressure against the side and is moved with the part in relation to one another. The tool and/or the part are heated. The cut parts of the fibre plates are e.g. tracks and edges. The tool and parts are heated to such a temp. that the fibre plate in the area of the parts is compressed by a determined pressure. The tool is vibrated. - The device comprises a non-cutting tool with one side formed to correspond to the part complete final profile or part of it. The tool and/or the part are arranged to be heated and the tool can have a pressure applied against the part in order to compress the material in the area of the part, the part and the tool being movable in relation to one another.
