Switzerland’s Uster fosters two-way track to optimum fibre cleaning

Uster has fostered a highly effective dialogue with its customers – so that spinning mills play a continuing role in the development of system improvements. Customer needs are fed back directly to R&D experts, leading to constant progress in fibre cleaning, with reductions in costs, less waste and a stress-free experience for the spinners.

The Uster Jossi Vision Shield illustrates this perfectly, with both the model T and model 2 well established in the market. Over 2,000 installations in spinning mill blowrooms around the globe testify to its success. But the Uster development teams continue to be driven by an ambition to explore still further improvements. Their work doesn’t necessarily result in a completely new fibre cleaning system, but it does make a valuable difference to spinners, which is well worth talking about, Uster said in a press release.

The unrivaled detection capabilities of the Uster Jossi Vision Shield come from the sensors and the powerful imaging recognition technology. This is a sophisticated image analysis technique perfected by Uster. The smallest particle of contaminant will be picked out, helped by unmatched image recognition. 

“Such great detection performance might make some spinners nervous that too much good cotton might be ejected with the contaminants. But they can relax with Uster Jossi Vision Shield! Its speed measurement feature even provides a notable reduction in waste. By continuously measuring the velocity of the passing cotton tufts, the system can adapt the duration of each ejection, so that a minimum of material is removed with the contaminant. Mill trials have proved that optimising ejection times in this way results in significantly less waste per ejection,” the release added.

The software built into Uster Jossi Vision Shield is under continuous improvement. Algorithms are adapted to take account of customer feedback, which is proactively requested and passed on via Uster Service to the research and development teams. This two-way connection between the mills and Uster R&D is the secret of success in developing exactly what customers need. The fact that the information passes different USTER experts makes it a sophisticated solution. Each of them – also from textile technology and product management department – adds knowledge and experience. Uster literally means it when saying “your feedback is important to us.”

Ongoing integration of practical experience in the software and continuous deployment has become standard for Uster fibre cleaning. “We consider the fact that inputs of customers are applied with each software update as part of our success model,” said Suresh Kris, vice-president global after sales and service. The information flow was maintained, even in pandemic times, as Kris and his teams stayed in contact with customers via digital communication.
