Uster brought out new yarn clearer and monitoring system

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 were displayed at ITMA ASIA + CITME.

The brand-new Uster Quantum 4.0 yarn clearer offers very good 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.

The novel Uster Quantum 4.0 yarn clearer.

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.

Uster Q-Bar 2 is best described as a formation monitoring system, because of its 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.

Uster Q-BAR 2 monitors the fabric at the earliest point with automatic, in-line inspection.

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.

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.
