KARL MAYER Technical Textiles presented an extraordinary upgrade to their highly sought-after weft insertion machine, the WEFTTRONIC® II G, at ITMA 2023 in Milan. The remarkable enhancements showcased their deep market understanding and received an overwhelming response.
The machine's innovative features, including the VARIO WEFT laying system, edge stabilization solution, weft tension monitoring, and central suctioning device, captivated the attention of visitors. The WEFTTRONIC® II G was displayed in the popular 213" working width, ideal for geogrid production.
The highlight of the upgrades was the VARIO WEFT, which revolutionized weft patterning and delighted customers. This electronic solution allowed for effortless, rapid, and flexible changes in weft patterns without any mechanical interventions during threading. It offered unparalleled freedom in repeat length, significantly reduced selvedge waste, and introduced a novel threading principle.
By employing a stop-and-go operation of the transport chain and a new movement curve of the supporting sinker, the yarn was fed into the fabric according to the desired pattern. Spaces within the fabric were created by pausing the transport chain and dipping the supporting sinker under the weft yarn.
The flexibility of VARIO WEFT in weft patterning sparked discussions and inspired new product ideas among customers during ITMA. Moreover, the elimination of vacant positions in the transport chain led to a reduction in waste, positively impacting costs and the environment.
In the conventional process, the empty positions resulted in discarded yarn sections, escalating both expenses and environmental consequences. By considering the absolute savings potential and the count of weft yarns in the fabric, the overall benefits of the upgrade became apparent.
With the WEFTTRONIC® II G featuring the groundbreaking VARIO WEFT, KARL MAYER Technical Textiles not only redefined weft insertion but also offered their customers unmatched profitability, increased flexibility, and environmentally conscious production.
