The invention relates to a method and a device for manufacturing a multi-layer compression moulded element and to a compression moulded element which is embodied as a multi-layer carbon brush and has at least a first and a second moulding layer, in which, in order to carry out the method, a multi-component mould which comprises a moulding element and a mould slide arrangement interacts with a moulding die, and in which a mould which is defined by the selected configuration of the moulding slide arrangement in the moulding element is filled by filling moulding segments which are formed one next to the other with moulding material in chronological succession in a transverse direction with respect to the axis of the moulding die, and by the compression moulded element being subsequently formed by moving the moulding die and moulding slide arrangement relative to one another in the mould.

Method for manufacturing a multilayer compression moulded element

A method for production of a multi-layer carbon brush including at least two electrically-conducting functional layers made from carbon material and at least one insulation layer made from an electrically-insulating material, running between consecutive functional layers. According to the invention, the corresponding multi-layer carbon brushes and the layers with desired thickness can be produced by applying the carbon material and the electrically-insulating material in a mold in a sequence corresponding to the layer sequence of the multi-layer carbon brush for production in powder form, then pressed and finally heat-treated.

Method for production of a multi-layer carbon brush

A resin bonded graphite material which is especially suitable for use as an electric contact, and a method for the production of this resin bonded graphite material. According to the invention, the resin-bonded graphite material if formed from a mixture of carbon black containing electro-graphite with a unburned graphite content of Rwherein R&#x2267;30 percent by weight, electro-graphite free of carbon black as well as binding agents. The material has a specific electrical resistance Wwherein W&#x2267;3500 &#x3bc;&#x3a9;m, and use of the resin bonded graphite material as an electrical contact makes possible substantial exclusion of radio interference.
