) and final product (i.e.,

) along their entire manufacturing process. Most important process parameters a spinning mill has to control are: quality of the incoming fibers, yarn evenness, hairiness, tensile strength and elongation, contamination with disturbing materials, twist, friction, etc. By measuring these parameters, the instruments can be used as tools for a mill-wide quality assurance process. An overview of Uster products applied in the spinning mills: * The "Uster Tester", a laboratory system for the measurement of evenness, thick places, thin places, neps, hairiness, diameter, dust, trash, fineness of yarns * Yarn tensile testers - at conventional (5m/min) and high speeds (400m/min) * Yarn fineness tester * Yarn strength tester (Tensorapid) * Yarn twist tester * Yarn friction tester * Single fiber measuring system (AFIS = Advanced Fibre Investigation System) * Fiber bundle measuring system (HVI) *

(Uster Quantum), which is mounted in the automatic winding machine, i.e., "on-line" * Defect classification instrument (Classimat) * Cotton cleaning system (Vision Shield) While developing these different testing instruments, often the first of their kind, Uster also had to invent either the measuring method or the suitable measurement parameters. Some examples: For comparing such quality parameters in the spinning laboratory with those of other spinning mills worldwide, Uster established a number of benchmarks. The first so-called "Uster Statistics" were introduced in 1957 and have been periodically updated to account for the technical and regional changes in the industry. These statistics are an important element in the trading of yarns, as they allow yarns to be objectively specified and referred to a worldwide quality level. Uster Technologies also runs the Usterizing certification program for spinning mills.

History

* The roots of the company date back to 1875, when an aerial telegraphy workshop was established in Uster, Switzerland. * 1927, the production of weaving preparatory machines started under the brand Uster * 1944, the company started research and development for textile electronics, mainly for the Swiss spinning mills * 1948, the company launched the first ever yarn evenness tester under the name "Zellweger Uster". Being one of the first of its kind, this instrument and its following product generations became well known worldwide, which explains why the company was able to file "Uster" as a registered trademark, while being located in the city of the same name. * 1957, the company published the first set of quality standards for yarn evenness, called Uster Statistics * 1989, acquisition of Schaffner Technologies (USA) * 1990, acquisition of Spinlab (USA) * 1993, acquisition of Peyer (Switzerland) * 2003, buyout from Zellweger Luwa by Management and two private-equity investment companies * 2005, establishment of development and manufacturing site in
