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.
Claims8
A package of textile fibers comprising a continuous core of yarn, said yarn being compactly folded within convolutions of a uniform helically, compactly wound mass of yarn, said yarn compressed within a long tube of flexible material, said folded and helically wound mass of said yarn being compressed in said tube so that said mass of said yarn expands after removal of said tube from around said mass, said yarn being compressed with a compressive force that is entirely longitudinal along the axis of said long tube.
A package of fluid conveyable material comprising a continuous core of said fluid conveyable material compactly folded within convolutions of a uniform, helically compactly wound mass, said conveyable material compressed within a long tube of flexible material, said folded and helically wound mass of said conveyable material being compressed in said tubes so that said mass of said conveyable material expands after removal of said tube from around said mass, said yarn being compressed with a compressive force that is entirely longitudinal along the axis of said long tube.
