Abstract
The present invention provides a novel extrusion apparatus including a flow channel having a modified preland channel that functions as a flow transition zone. The flow transition zone changes the widthwise flow volume of a stream passing therethrough so as to provide for substantially equal flow volume of the stream across the flow channel width as the stream exits from the transition zone.
