Product Description

The Web Tech Tension Control System automatically controls tension during manufacturing and various treatment processes of paper, foil, film, rubber, fabric and so on. When a web of these materials is unwound or rewound the web tension varies as the roll diameter of the material changes. Web tension must be maintained at a constant level to prevent wrinkles, sags, and changes in width or thickness or breakage of the web. In printing processes variable tension causes a paper web to stretch or shrink, causing sudden register errors. This problem necessitates tension control.
