The invention relates to a method for producing a fitting (2,3) for the treatment of aqueously suspended fibrous material (1) in a treatment gap (4), consisting of a base body (5) with treatment elements (6) facing the gap (4). In this case, the expenditure on production shall be reduced by virtue of the fact that the treatment elements (6) are applied at least partly as a layered structure consisting of a liquid or solid material and are thereby subjected to a physical or chemical curing or melting process.
