<p>The present invention relates to nozzle tip for use in a three-tube filling machine for the production of heating elements in an its enterity continuous concave shape, that increases the material flow per time unit and therewith increases the productivity rate in the production of tube-shaped heating elements. Closer determined, a nozzle tip, where the number of guide wings can be varied, where said guide wings lay between concave radii and where the free surface between the guide wing and the element tube, determinant for the flow of the filling media, is maximized for a maximum flow of filling media.</p> |
