Abstract
An apparatus for processing a fabric has a drum with an elliptically-shaped cross-section having a pair of narrow sides and a pair of broad sides. Each of the narrow sides have an impact edge. Each of the pair of broad sides has a sliding surface. The drum has a differential helical expander formed on an outer surface thereof. A bearing and drive shaft set are affixed to the drum so as to impact rotational motion to the drum.
Claims3
