ABSTRACT:
In the manufacture of a fiber tow, particularly cellulose acetate tow, a stuffer box crimper has one roller adapted to induce crimp into the tow. This roller induces crimp by preferentially weakening a portion of the tow. This roller has an axially grooved surface. This roller may be located in the stuffer box crimper or before the stuffer box crimper.
