  • Method and device for pressure balancing of hoses at extruding of two components
    Patent number: 5286433
    Abstract: A method and apparatus for supplying two different components at two different flow rates to an extrusion head. A first component is delivered to an extrusion head through a first hose at a predetermined pressure. A second component is delivered to the extrusion head through a second hose at substantially the same predetermined pressure as the first component. The second hose extends partially through the first hose so that both components are delivered to the extrusion head at constant equal pressures.
