Zellweger Uster, Inc is to join forces with Fruit of the Loom in the renovation of Leesburg Yarn Mills in Leesburg, Alabama. Uster quality systems will measure and control the quality at spinning and drawing, which will be complemented by the extensive Uster yarn-testing laboratory. The Uster Quantum Yarn Clearers will be installed on all Rieter R20 open end spinning machines making this the largest single installation of its type in the world. In addition, Uster SliverGuard will be installed at the drawing process to assure consistent quality sliver will be available for spinning.
