Abstract
An aspirating cutter severs a traveling yarn and exhausts same to a remote location. The cutter comprises a housing and a hollow suction tube projecting forwardly from the housing. A rearward suction is generated in the suction tube. The suction tube includes first and second slots opening forwardly at the front end of the suction tube, which slots are arranged to receive a traveling yarn. The first slot includes a first cutting edge. An outer tube is rotatably mounted on the suction tube. The front end of the outer tube includes a recess and a projection. The recess is large enough to expose the first and second slots. The projection includes a second cutting edge. When the outer tube is rotated, the first and second cutting edges are moved into a yarn cutting mode to sever a downstream portion of the yarn such that the upstream portion of the severed yarn is sucked into the suction tube. One of the cutting edges is inclined, to produce a scissoring action urging the yarn toward the suction tube.
