Product Description

Web tech multi drive synchronised 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 multi drive synchronised control system.
