SINGLE IMPINGEMENT BULKING JET

The present invention is directed to a non-interlacing expirating yarn bulker comprising a body having an enclosed yarn passage extending therethrough. The yarn passage includes an inlet region, a throat region and an expanding region; a replaceable wear member is insertable into a body of the jet having a yarn passage with an inlet region and a throat region. When inserted into the body the channel defines at least a portion of the inlet region of the yarn passage; a yarn bulker that includes a stuffer chamber section communicating with the yarn passage for forming a wad of yarn, and, a yarn transport section. The yarn transport section is formed by a tubular member having a first and a second end and an axial bore extending therethrough. Its first end communicates with the stuffer chamber and adjacent to its second end, it has a passage which communicates with the axial bore. A deflector plate attached to the tubular member adjacent to the second end thereof is inclined to the axis of the bore and toward the passage in the tubular wall member at an angle of thirty (30) to about sixty (60) degrees. The deflector plate is perforated by a plurality of slots defining a plurality of tines.
