Abstract: A system and method for manufacturing erosion control filter socks consists of a mass of filtering material, a material supply assembly, an assembly section, and a packaging section. Switchgrass is used as the filtering material. Upon receiving the mass of filtering material, the material supply assembly appropriately transfers the filtering material to the assembly section. The filtering material is loaded into a receiving sock with the use of a sizing funnel in the assembly section to create a filter sock. The density of the filtering material within the filter sock varies. When loading is complete, the packaging section sizes the filter sock accordingly. When sizing the filter sock is complete, the filter sock is wrapped in a plastic cover so that the filter sock can be conveniently transported and installed.
