Abstract: An improved aspirator-shear unit for rapidly moving strand of yarn in which an aspirator nozzle is arranged with its axis in closely proximate more or less parallel relation to the yarn path, a fixed shear blade is situated laterally between the nozzle opening and the yarn, and a movable snubnosed shear blade is projected from an inoperative position on the opposite side of the yarn path from the aspirator nozzle and fixed blade across the yarn path into shearing relating with said fixed blade and finally to a deflecting position with its leading edge generally aligned with the nozzle opening. Preferably the aspirator nozzle axis is inclined at a small angle with respect to the yarn path to reduce the clearance from the yarn path required to physically accommodate the nozzle.
