Harris Tweed Hebrides praises SL smart weft-straightener for precision and efficiency

David Stewart, Harris Tweed Hebrides Ltd is very satisfied and states: „The SL smart weft-straightener performs very well with our product. The traversing camera is exceptionally accurate and automatically adapts to a wide range of weaves. The system of skew and bow rollers allow precise alteration of the weft without the possibility of damage to the fabric. It requires very little input from the operator and minimal maintenance, resulting in increased productive times. The addition of the touch screen control panel allows the operator to view the current weft position in real-time, ensuring that the fabric is within the accepted parameters. Excellent support from PLEVA team.”

Besides those advantages, also a positive ecological impact is achieved: Due to the first-time-right-principle, only one round through the production line with the fabric is needed to produce directly the aimed result. This saves energy and valuable resources. In addition, due to the higher quality of the goods, there are no more costly readjustments or wasted fabrics and complaints can be reduced drastically. This is not only good for textile finishing companies and customers, but also for the environment.
