ABSTRACT:
An apparatus and method for melt spinning a plurality of downwardly advancing multifilament polymeric yarns, and winding the advancing yarns into respective packages. Each of the advancing yarns is brought into contact with a separate yarn delivery mechanism which acts to control the yarn tension before the yarn is wound into a package. Thus, the yarn tension of all of the yarns can be made substantially the same when they are wound into packages, which permits all of the packages to have the same winding structure and the same packing density.
