Abstract
A system for processing plant material is provided which separates plant fibers from the woody portions of the material to produce a commercially desirable length of fiber and to grind the shorter woody portions that have been separated from the longer fibers to a desirable size which has found use in certain commercial applications. The current system is well suited to process the tough fibers of the North American strain of flax straw, and will also find utility in processing other bast fibers, such as jute, hemp, ramie, and kenaf.
