Abstract (en)
A multilayer-structured filter assembly (9) for press mould (1) for manufacturing cementitious products comprising a perforated plate (10), a first layer-structure (11) attached to the perforated plate (10) and a second textile layer-structure (12) attached on top of the first layer-structure (11). The provided filter assembly (9) allows dehydrating a concrete slurry mix without passing particulate material and ensures smooth surfaces or defined dimple effects on the manufactured product without producing shadow marks or high pressure stress to the filter-assembly. The provided filter assembly is intended to be used as face and/or back filters in press moulds (1).
