A device for moulding 'green' blocks or electrodes for the manufacture of anode and cathode carbons for the smelting industries, with particular reference to the electrolytic smelting of aluminium, utilizing a vibratory or shaking motion, in which the paste which is to form the blocks or electrodes is filled into a mould. The mould comprises a plane, horizontal base or table, vertical walls or sides of which at least one is removable to facilitate the ejection or discharging of the finished block, and a pressure weight slidable in vertical guides, the downward-facing surface of which weight covering essentially the whole of the cross section of the mould. On the weight, and only on the weight, there is disposed at least one vibration generator. The base of the mould is stationary, and the walls or sides of the mould are so arranged as to be firmly fixed to the base during the moulding process.
