Abstract
A winding apparatus which includes a plurality of yarn supply package stations for holding a plurality of packages of multifilament yarn, a processing station for receiving yarns from the yarn supply packages and processing the yarn, and a take-up package. The improvement comprises a yarn randomizing device positioned downstream from the supply packages and upstream from the processing station for intermixing filaments within a single yarn and among the plurality of yarns in a random and irregular manner before delivery of the yarns to the processing station thereby preventing patterning in the processed yarn. In one embodiment the randomizing device comprises a air vortex and in another, a rotating beater.
