Uster has launched Uster Q-Bar 2, a unique formation monitoring system for fabrics inspection. The system monitors the fabric additionally at the earliest point, the critical stage in fabric formation, with automatic, in-line inspection. Uster is the world’s leading provider of quality management solutions from fibre to fabric, headquartered in Switzerland.
Q-Bar 2 is best described as a formation monitoring system, because of its ingenious positioning directly at the interface of warp and weft threads. That allows rapid response as soon as a defect appears, avoiding long-running or repeating faults. Alarm and stop signals alert the operator to correct problems immediately, and early detection reduces second quality and material loss, as well as minimising the need for post-production checks, according to a media statement by Uster.Uster has launched Uster Q-Bar 2, a unique formation monitoring system for fabrics inspection.

For weavers, these advantages represent genuine and long-awaited innovations with a positive impact on both productivity and quality. Weaving defects can have various root causes, so Uster Q-Bar 2 provides different algorithms to identify specific defects and their causes. This inbuilt knowledge can prevent defects within the weft insertion cycle. Its enhanced detection position in the fabric formation zone means the warp is monitored even before it is traversed by the weft, a truly unique benefit. It allows detection of incorrect warp positions, missing warp, loose warp ends, and even pattern irregularities, Uster said.
Another important innovation is the control of weft irregularities. By monitoring each inserted weft in the formation area, Q-Bar 2 primes users to react to weft irregularities at the earliest possible stage. At this point, it can detect weft-related defects such as double picks, broken weft or slubs and loops, according to Uster.
Defects that become visible only in the woven fabric are the nastiest threat. Often, it’s too late when defects such as reed marks, dirty yarns or floats are spotted – but it can’t happen with Uster Q-Bar 2. Its fabric inspection algorithms detect even ‘invisible’ defects in the fabric. It’s the simple solution to improving fabric yield by automated formation monitoring. Q-Bar 2 also monitors critical machine units in the formation zone. If there is a problem here, the system makes it easy to identify and eliminate it, preventing further defects and again maximising fabric yield.
Another element of the total supervision provided by the formation monitoring system is its special focus on the selvedge area. This is not only critical for an efficient weaving process, it is also important in further process steps. Specific algorithms detect irregularities in the selvedge, as well as broken leno, but also identify any pattern defects. Continuous pattern monitoring flags up incorrect patterns at the earliest stage, so the loom can be stopped and the problem fixed before many meters of fabric are wasted.
The system has a permanent eye on the fabric width, an essential factor for further processing. For this reason, Q-Bar 2 provides continuous width measurement of the woven fabric, from loom setup to full roll. The technology in this new formation monitoring system is impressive, but Q-Bar 2 is highly developed in many other aspects too. Its attractive industrial design is also ergonomic, so users have easy access to all important parts. Weavers appreciate its simple installation on existing weaving machines.
“Formation monitoring is the answer to market requests. Weavers demand zero defect standards, increased sustainability by waste reduction and they want to produce the fabric meeting specific quality requirements. Independent of the fabric application, Uster Q-Bar 2 is a game-changer. For the first time, weavers can actually prevent weaving defects instead of only reacting to them,” Michelle Salg, product manager for fabric inspection at Uster said in a statement.
