DIE FOR EXTRUDING A FLUID STREAM

摘要

A die useful in coating and extrusion processes has a housing and an insert removably received in a chamber of the housing. The insert controls to some extent the characteristics of fluid flow in the die as well as the fluid flow exiting the die. The insert is elongated and is round in sections perpendicular to its longitudinal axis, so that it may be inexpensively made by a lathe. As such, a number of inserts of varying configurations may be retained on hand and used as needed to vary the flow characteristics when desired.
