Beschreibung
Zusammenfassung:	The present invention provides a method and apparatus for uniformly spreading and converging, that is, altering the width of a band of fibers or threads arranged in parallel, while the band travels in a lengthwise direction, into a predetermined width and thickness with the least amount of uneveness. The fibers are spread and converged by placing the band of fibers on a rotating conveyor in which the forward path of travel widens and the return path narrows. The resulting fibers are well adapted for subsequent textile processing.
