<p>Method and device to pressure balance hoses at supply of two different components with substantially the same pressure to an extrusion head (13), where the flow of the second component is substantially below the flow of the first component, e.g. at thermosetting plastic extrusion. The first hose (10) for supply of the first component during at least a substantial part of the path to the extrusion head (13) is arranged to enclose the second hose (11) for supply of the second component.</p> |
