Reverse Dutch Weave Filter Belt

Automatic Screen Changer Belt · Dense Warp/Sparse Weft · For Plastic Extrusion

Stainless steel reverse dutch weave filter belt, also known as automatic filter belt or reverse dutch mesh, features dense warp and sparse weft. Produced by reverse dutch weaving process, it is the dedicated continuous filter medium for automatic screen changers in plastic extrusion. Thick weft wires provide structural support while fine warp wires deliver precision filtration, enabling non-stop continuous melt filtration.
