<p>A flexible membrane is attached to a holder for controlling flow in an extrusion die. The membrane includes a horizontal portion, first and second curved portions adjacent the horizontal portion, first and second offset portions adjacent the first and second curved portions, and first and second edges adjacent the first and second offset portions. The membrane is formed of a single piece of material. The flow control device including the flexible membrane may be produced by fabricating a membrane holder from a material, fabricating a flexible membrane from the same material, joining the flexible membrane to the membrane holder, and hardening the membrane holder and membrane.</p> |
