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, such as a rotating roller having threads thereon for reciprocating the yarns from one side of the roller to the other.
