Woven fabrics are frequently displaced when feeding into the machine to cause failure in production and the waste of materials.

With our unique and own developed correction device which is specialized for mask production machines, the pass rate and efficiency are greatly improved!

Features:
- Rapid response by high speed CPU
- Support Ultrasonic sensors, opto sensors to deal with different materials
- Top quality of bearing with high precision (+/- 1mm) and low noise
- Durable and long working life
- Easy to be installed

Traditional unwinding tensioners are mainly mechanical, using physical contact to generate a friction force to control the tension.

However, the tension keeps increasing when the unwinding diameter is getting smaller so that frequent manual adjustment on the tensioner is required. ETR series tensioners are able to reduce the output tension values gradually depending on the
unwinding diameters to keep the tension constant during the process.

Simply setting the initial tension value required and no more adjustment is needed, which is convenient and stable to be used.

To meet 99.99% pass rate for masks production and increase 30% speed of producing with the precise tenison control of non-woven fabric.
