Since 2018, the renowned Uster quality systems include fabric inspection – and ITMA 2019 has seen the launch of the first major innovation to be developed since the acquisition of automatic vision inspection company Elbit Visions Systems (EVS).

Fabrics makers will already be familiar with the successful, industry-proven solutions Uster EVS Q-Bar, Fabriq Vision and Fabriq Shade, which today are used worldwide to inspect upwards of 60 million metres of fabric per day. At ITMA in Barcelona, in June, Uster Q-Bar 2 and Uster Fabriq Expert have been launched and explained to show visitors.

For fabrics manufacturers, the competitive nature of the textiles market means that reliable quality is a requirement, and defects are unacceptable to their customers. Uster Fabriq Expert and Uster Q-Bar 2 aim to support textile mills in guaranteeing the delivery of the desired roll quality, using the best technology available for monitoring and improving production at the earliest-possible stage.

That includes locating any defects quickly, supporting identification of the root causes and initiating corrective action. The expertise of EVS technology – with intelligent visual detection and fault-recognition algorithms – is now enhanced by Uster’s overall experience in quality management systems for the wider textiles industry, the company explains.

Direct impact on business success

Uster Q-Bar 2 represents the next generation of the original on-loom monitoring and inspection system, offering user-friendly design and operational improvements for weaving. An inspiring Uster design built on years of EVS experience brings many advantages, including indication of the defect location, and better access to make maintenance tasks easier.

The Uster Q-Bar 2 is positioned immediately behind the reed on each machine. This means the operator can respond quickly to alarms and stop signals, to correct problems immediately and prevent quality issues from continuing, thus minimising material waste. A red LED guides the operator to the exact position of defects, and lights at the side of the unit show system status.

Fabric faults are categorised and saved, creating a defect map for each roll which can be recalled and reviewed later via the intuitive touchscreen.

Uster Q-Bar is already making a significant impact on the business success of users. In one example, a US technical textiles producer reports that it has increased sales volumes through the ability to guarantee seamless fabrics to its customers. This firm produces base-layer material for coating, an application in which defects larger than 9 inches are unacceptable, as they would require cutting and seaming.

Full on-loom quality transparency

“Uster Fabriq Expert is the key to early detection of quality issues, based on comprehensive quality data gathered during on-loom inspection of fabrics. It provides weavers with an overview of their entire installation, via Uster Q-Bar 2 systems fitted over each machine,” the company says.

The quality data can be used to compare the performance of the same styles on different machines, for example. Another benefit is an indication of when to replace spare parts, preventing faults which could occur with worn-out parts.

“Importantly, this knowledge is a considerable scale-up on the normal weaving operator’s ability to feedback observations over several looms,” Uster continues. The whole-mill picture from Uster Fabriq Expert makes the results more representative of the true picture in the mill.”

Quality partner

“Combining the industry-leading technology of automated vision-based inspection with Uster’s unrivalled stature in quality management systems and services creates the perfect dream team for fabric manufacturers,” the manufacturer reports.

“They can now have access to highly effective automated fault detection, as well as total transparency of weaving quality performance, provided during on-loom inspection. Uster Fabric Inspection offers real benefits for weavers in terms of both customer satisfaction and their own long-term business success.”
