Abstract
A crossed belt false twist device for texturing yarn which includes two belts supported by pulleys to provide two free runs crossing at a crossing region which is nearer to one pulley in each case than to the other pulley. Longer belts can be used than heretofore known without sacrificing stability and control, thereby also reducing wear and allowing cooler running.
