Abstract: A device for attaching a filter mesh to the drum of a rotary vacuum drum filter has a number of support elements uniformly disposed about the circumference of the drum and extending along the axial length thereof for carrying the filter mesh and forming individual cells beneath the mesh. At least one filter mesh clamping element is provided between adjacent support elements which includes a spacing body attached to the exterior drum wall and a strip disposed thereabove on the filter mesh and a retainer joining the strip and the spacing body. The spacing body has approximately the same height as the support elements so that the filter mesh is not deformed by the attachment.
