Valid Magnetics ETR2000 Tensioner for Masks Production, Label, Packing, Rolling Machines

详情

Description
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 *9.*9% pass rate for masks production and increase *0% speed of producing with the precise tenison control of non-woven fabric.
