Abstract

A filter for use in a concrete press mould (10), the filter (19) comprising a fabric being knit or woven at least in part from heat meltable yarns and having a fabric density which permits the passage of water therethrough but prohibits the passage of particulate material (17), the filter being bounded around its periphery with at least one continuous imperforate band (32) integrally formed with the fabric by fusion of said heat meltable yarns.
