ABSTRACT:
A generally ear-shaped ring traveler, designed for movement with minimized ring to traveler friction and aerodynamic resistance along the inside of a ring of a yarn twister or like machine, is disclosed. The cross-sectional configuration of the traveler at any given transverse plane is characterized by an oblong shape having a relatively wider or blunt leading edge and a relatively narrower or less blunt trailing edge, with the cross-section being airfoil-shaped in the main body section and in each of the upper and lower transverse arms so as to cause lift forces opposing the yarn forces and the centrifugal force to be generated, and generally drop-shaped in the transition regions between the arms and the main body section so as to provide a generally neutral streamlining effect. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.
