Abstract
An extrusion die is provided with an external deckle assembly, an internal deckle assembly, or both. One embodiment provides an extrusion die having a wedge-actuated external deckle assembly. A seal member of the external deckle assembly moves to a sealed position in response to movement of the wedge in a first direction. Another embodiment provides an extrusion die with an internal deckle assembly having a deckle rod support system. The internal deckle assembly includes a deckle rod and a transversely elongated support engaged with the deckle rod to restrain the deckle rod against bending.
