Title (EN) VARYING TRANSITION ZONE MANIFOLD
(FR) COLLECTEUR À ZONE DE TRANSITION VARIABLE
Abstract:
(EN) The present invention provides an extrusion die that includes a manifold transition zone that comprises a varying included angle. The varying included angle provides unparalleled freedom of design to achieve diverse fluid dynamic objectives, such as reduced residence time across the manifold width, reduced transition stagnation, improved streamlining of the mass flowing through the manifold, and reduced differential clamshell deflection across the flow channel width. The manifold may be transformed from one cross-sectional shape to another cross-sectional shape beneficially related to the varying included angle, including change from a generally extended cross-sectional shape to a generally teardrop-shaped cross-section. The manifold may include a first transition zone portion that includes the varying included angle, and a second transition zone portion that includes a constant included angle, and that is particularly beneficial for receiving an internal deckle.
(FR) La présente invention concerne une filière d'extrusion qui comprend une zone de transition de collecteur qui comprend un angle inclus variable. L'angle inclus variable offre une liberté de conception inégalée pour atteindre différents objectifs de dynamique des fluides, tels qu'un temps de séjour réduit dans la largeur du collecteur, une stagnation de transition réduite, une rationalisation améliorée de la masse s'écoulant à travers le collecteur, et une déviation différentielle de clapet réduite sur la largeur du canal d'écoulement. Le collecteur peut être transformé d'une forme de section transversale à une autre forme de section transversale bénéfiquement associée à l'angle inclus variable, comprenant un changement d'une forme de section transversale généralement étendue à une section transversale généralement en forme de goutte d'eau. Le collecteur peut comprendre une première partie de zone de transition qui comprend l'angle inclus variable, et une deuxième partie de zone de transition qui comprend un angle inclus constant, et qui est particulièrement bénéfique pour recevoir un bord interne.
