Abstract
A process for converting a continuous multifilamentary yarn into a staple-like yarn involves continuously conveying continuous multifilamentary yarn onto a rotatable wheel having a peripheral yarn receiving groove and at least one radially disposed needle within the wheel and in registry with the groove. The needles are in various stages of retraction and extension depending upon the relative rotational position of the wheel. By laterally contacting the multifilamentary yarn in the groove, the barbs of the needles catch and break a fraction of the filemants from the side of the yarn so that the yarn is not forced upward out of its grooved path.
