Uster has introduced the new Quantum 4.0 yarn clearer and the Q-Bar 2 recently alongside the new Quality Expert software with latest Mill Dashboard feature. These major developments are ready to go live at ITMA ASIA + CITME in Shanghai.

Capacitive and optical sensors in one

The brand-new Uster Quantum 4.0 yarn clearer offers the advantages of both capacitive and optical sensor technologies for intelligent yarn quality control. It enables this through a simple capacitive/optical switch. This allows greater flexibility in the yarn types which can be produced, while also dealing with factors such as humidity variations.

Using its unique Smart Duo technology, the Quantum 4.0 operates both sensor channels intelligently in tandem, through an innovation known as Cross Clearing. This locates and eliminates hidden defects by means of a double check, in which the main sensor’s signal is supported by the assistance sensor.

In addition to identifying issues at winding, defect prevention at source is now possible. Thanks to many extra intelligent analytical features, the Uster Quantum Expert, included in the clearer’s product offering, enhances process control and prevention of defects, through Total Contamination Control, Ring Spinning Optimization and the RSO 3D Value Module.

Fabric inspection at the right position

Uster Q-Bar 2 is best described as a formation monitoring system, because of its ingenious positioning on the loom, directly at the interface of warp and weft threads. The monitoring at the earliest possible stage 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. Early detection reduces second quality and material loss, as well as minimizing the need for post-production checks.

Q-Bar 2 provides different algorithms to identify specific weaving defects and their causes. The detection position in the fabric formation zone means the warp is monitored even before it is traversed by the weft. It allows detection of incorrect warp positions, missing warp, loose warp ends and even pattern irregularities.

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.

Key people, key data

The introduction of the latest Mill Dashboard for the Uster Quality Expert can bring significant changes for operators in spinning mills. The new version of the Mill Dashboard presents key data directly to key individuals in the spinning mill, so they can react rapidly to any quality deviations. It also ensures greater transparency on the shop floor.

The latest release of Uster Quality Expert is available for connection, and all key quality parameters from laboratory and in-line instruments can be displayed, targeted to individual needs and preferences.
