Abstract: Described is a self-cleaning extrusion orifice assembly including an enclosure, a cylindrical body inserted into the enclosure and terminated by an extrusion orifice. The self-cleaning extrusion orifice assembly is operated by a pressurized air flow. The pressurized air flow flushes surfaces of some elements of self-cleaning extrusion orifice assembly removing debris that could be deposited on these surfaces. In addition, some elements of self-cleaning extrusion orifice assembly are configured to scrape extrusion process debris from the same surfaces.
