Abstract: An extrusion die is provided with an adjustable end seal assembly. The extrusion die includes a die body, and the adjustable end seal assembly includes an end seal device and a wedge mechanism. The adjustable end seal assembly has an engaged configuration and a disengaged configuration. When in the engaged configuration, the adjustable end seal assembly is held forcibly against the die body. When in the disengaged configuration, the adjustable end seal assembly is either spaced apart from the die body or held against the die body with less force than when in the engaged configuration. Methods of operating such an extrusion die are also provided.

Abstract: An extrusion die includes a first die body having a first lip, and a second die body having a second lip. A lip adjustment assembly is mounted to the first die body and configured to adjust the position of the first lip relative to the second lip to thereby adjust a thickness of the extrudate that exits the gap. The lip adjustment has translating unit that includes translator, a mounting member coupled to the translator, and a rod coupled to the mounting member so that the translator is fixed with respect to the rod. The mounting member is configured to be accessible from the exposed end to decouple the translator from the rod so as to remove the translator from the lip adjustment assembly.
