Abstract

An extrusion die with fastener tension adjustment assembly can be formed of a die body that includes a first die body portion and a second die body portion. The extrusion die can have a lip body connected to one of the die body portions using the plurality of fasteners. In one configuration, the fastener tension adjustment assembly has an elongated body operatively connected to each of said plurality of fasteners. The fastener tension adjustment assembly is movable towards and away from the lip body, thereby simultaneously adjusting an amount of force applied to each of said plurality of fasteners. Because the fastener tension adjustment assembly can simultaneously adjust the amount of force on each of the plurality of fasteners, it can eliminate time consuming fastener-by-fastener adjustments on the extrusion die.

First claim

The invention claimed is:

1. An extrusion die, comprising:
a die body,
a lip body,
a plurality of fasteners,
a fastener tension adjustment assembly comprising an elongated body operatively connected to each of said plurality of fasteners, and
a flow channel terminating in an outlet orifice,
said die body including a first die body portion and a second die body portion forming the flow channel therebetween;
said lip body being connected to one of said first die body por…
