  • Apparatus for producing slub effects in yarn strands
    Patent number: 5317791
    Abstract: An apparatus for air jet processing of threads of yarn to create fancy effects in yarn. The apparatus comprises at least one pair of reciprocally moving triangular profiles which move across the paths of moving yarn strands. Each triangular profile is separately mounted on a driving shaft and each moves opposite the other in order to create slack portions in the moving strand that are then taken up by an air jet to create slub lengths. The overall yarn processing system contemplates at least one pair of first and second feed rolls that feed lengths of yarn to air jet machines.
