<p>FLOW CONTROL VALVE A valve for regulating the flow of molten polymer to a number of extrusion dies connected to a common manifold. The manifold has a primary flow channel which has outlets at each end to secondary flow channels which lead to the extrusion dies. At least one intermediate secondary channel is also disposed between the ends of the manifold, leading to another extrusion die or dies. A flow restrictor is disposed in each of these secondary extrusion channels to control the flow of polymer. F-9592</p> |
