Apparatus for randomizing multiple yarn strands

In a winding apparatus including a plurality of yarn supply package stations for holding packages of multifilament yarn, a processing station for receiving moving yarns from the yarn supply packages and processing the yarn, and a take-up package station, the improvement which comprises randomizing means positioned downstream from the supply packages and upstream from the processing station, said randomizing means for intermixing filaments within a single yarn and among the plurality of yarns in a random and irregular manner in a continuous process while the yarn is in motion before delivery of the yarns to the processing station thereby preventing patterning in the processed yarn, said randomizing means comprising a tube for receiving the yarn therethruogh and an air inlet communicating with the interior of the tube through the side thereof for directing pressurized air onto the yarn as it passes through the tube, said randomizing means also including pulsing means for delivering air to said tube at varying intensities.
