The adjustable grooved feed extruder developed at Rauwendaal Extrusion Engineering [246] uses a grooved feed section in which the depth of the grooves can be continuously adjusted while the extruder is in operation. Parallel developments have taken place in Poland at the Technical University of Lublin [244, 245). Earlier concepts have been developed [247], however, due to the complexity of the adjustment mechanism, these have not been applied on a wide scale.

Although extrusion is used commercially for rubbers, and for solid state forming of thermoplastic polymers, in the chapter only melt extrusion of thermoplastic blends will be covered. Interested readers will find in depth discussion on extrusion in recent monographs [Rauwendaal, 1986 White, 1992].

This chapter covers two main sections extruder hardware systems and extrusion functional zones. The first section identifies the primary components of the extruder and provides detail into their capabilities and size ranges. The second section describes how the hardware interacts with the material as it passes through the system. In other words, it provides a look at what is happening inside each zone of the extruder. The descriptions here are purposefully brief, serving as a foundation to support later discussions specific to blown film extrusion. If the reader is interested in pursuing this topic further, there are many books devoted entirely to the extruder and extrusion processes. For example. Polymer Extrusion by Rauwendaal [3] provides an excellent in-depth analysis. Other references are listed in the back of this book [4-6].

Many thanks go to another close friend and mentor, Chris Rauwendaal, for not only helping with the text of this book, but for teaching me so much about extrusion over the years. I am thankful for the text review and insight given to me by Robert Krycki.
