    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.

    Abstract: An extrusion die includes a plurality of studs, a tuning assembly and a restrictor member. The tuning assembly comprises a wedge member, first and second adjustment members, and an adjustment control having a rotatable single point adjustment member. The wedge member is coupled to first ends of the studs and includes a first and second plurality of channels within. The first and second adjustment members have a plurality of protrusions, each of which is positioned within a respective one of the first and second plurality of channels. The restrictor member extends in the longitudinal direction and is coupled to second ends of the studs. Rotation of the single point adjustment causes each of the protrusions to move within each respective channel forcing the wedge member, the studs, and the restrictor member to move in a direction that is substantially perpendicular to the longitudinal direction.

    Abstract: A method for replacing one or more components of a lip adjustment assembly mounted to a die body of an extrusion die is disclosed. Initially, a translating unit of the lip adjustment assembly is accessed through an exposed end of the lip adjustment assembly. Then, an adjustment actuator is removed from a translator of the translating unit. The translator is decoupled from a rod of the translating unit so that the translator is removable from the lip adjustment assembly and with respect to the rod. Next, the translator is removed from the lip adjustment assembly and a first component of the translating unit is replaced with a second component of the translating unit.

    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.
