Abstract

A filter arrangement for a machine for manufacturing concrete slabs, said machine comprising a plurality of mould frames (4); lower and upper press plates (6, 17) which cooperate with the mould frames (4) to form mould cavities (9) for concrete compound that contains a surplus of water; and channel systems (20, 21, 22, 23) connecting the mould cavities (9) to a vacuum source for evacuation of said excess, said filter arrangement including a filter cloth (25) of a plastic material for abutment against the side of a press plate (6, 17) facing the mould cavity (9). According to the invention the filter arrangement also includes a frame (26) of a flexible plastic material for sealing cooperation with the mould frame and having a rear portion (27) forming an attachment means for cooperation with an attachment means (35) of the press plate (6, 17) for attachment of the filter arrangement to the press plate. <IMAGE>
