Abstract
Abstract This high speed yarn take-up system consists of a pneumatic injector nozzle rotatably mounted off-center of a single flighted rotating screw. Yarn is injected into the area exposed at the trailing edge of the screw and compressed and moved forward in a compression chamber by the feeding of the screw. A plastic tube is continuously formed around the compression chamber to receive the yarn mass as it discharges, thus forming a tube of indefinite unlimited length and from 1/4 to 4 inches or larger in diameter. The tube may contain a single end or multiple ends of yarn. The yarn can be removed from the tube at high speeds by simply slitting the plastic as the yarn is pulled from the package.
