Abstract

The inner end of the cylindrical passage through the thread drawoff tube flares outwardly toward the fiber collection chamber. The flared portion includes a smooth margin adjacent to the inner tube end and a grooved region spaced from the inner tube end. The grooved region includes equidistantly spaced long longitudinal grooves in the passage surface and intermediate short longitudinal grooves between the divergent end portions of the long grooves. Circumferential grooves in the passage surface intersect the radial plane grooves. In cross section, the grooves have a depth equal to at least one-half of the full diameter of the thread being drawn off. The plane of at least one groove sidewall intersects the principal passage surface at an angle between 45 DEG and 90 DEG .
