ABSTRACT:
Yarn from a rotatable package of the type comprising a cylindrical support upon which the yarn is packaged by winding, is fed in a precise and certain manner to a source of utilization of the yarn. A drive roll is positioned in proximity to, but spaced from the yarn package, and is mounted for rotation about its longitudinal axis, the longitudinal axis of the drive roll being substantially parallel to the longitudinal axis of the yarn package. A resilient circular band having an annular cross-section is stretched over the package and the drive roll so that the band is urged against the exterior surface of both. A means is provided for driving the drive roll at a rotational velocity corresponding to the rate of consumption of the yarn, and guide means directs the yarn to the source of its utilization.
