A textile machine having suction apparatus for processing yarns continuously running at high speed to permit threading up, doffing and the like without stopping the machine, the apparatus comprising main yarn conveying ducts extending along opposite sides of the machine, each duct having a series of small diameter straight unobstructed passages of predetermined length spaced along and opening into the duct, the axis of each passage being of predetermined related length and diameter and being inclined at an acute angle with respect to the longitudinal axis of the duct. A suction fan draws air in through said passages for tensioning the yarn passing through the passages and establishing a column of yarn conveying air along the duct.
