ABSTRACT OF THE DISCLOSURE Apparatus for forming a tubular filter element comprising a cylindrical filter screen, and a central core centrally mounted in and spaced from the filter screen. An annular filter screen extends between the core and the cylindrical filter screen so as to provide a base of a container providing a moulding space otherwise defined by the core and the cylindrical filter screen. A duct for delivering a dispersion of fibres in liquid is provided peripherally around the top of the moulding space for accumulating a tubular mass of the fibres in the moulding space while the liquid is drained through; the screens. Means for applying pressure to the dispersion throughout its introduction into the moulding space is provided and a reciprocable imperforate screen is provided in sliding contact with the cylindrical filter screen for progressively uncovering the cylindrical filter screen as a mass of fibres builds upwards along the moulding space from the annular filter screen. The apparatus packs the fibres in circumferential direction more uniformly than is possible with prior techniques providing high filtering efficiency and a capacity to withstand high differential pressures.
