Gujarat web tech industries offers the most sophisticated auto web tension control system, gwt-710. This is based on microprocessor technology for controlling/maintaining constant tension on web of any machine of any converting industry.Some of the constructive Features are: it avoids telescopic winding to obtain tight and transportable rolls; in printing, it enables reduction in linear and side registration problem and web breakages; the material surface remains untouched; no separate load cell type sensor is required for tension control; there is considerable reduction in wastage of costly processing material; tension is controlled from zero to maximum at any speed. It has digital settings up to a resolution of better than 0.1% and digital taper version control. Digital presetting of tension avoids trial and error in setting tension every time. At starting/stopping of the machine, tension is controlled in such a way that there is no loose winding at winding/unwinding side. It has protection against jamming or overloads due to process material or any internal fault of the machinery. When the machine stops, torque on the motor goes in the sleep mode, which protects overheating of the motor. In auto web tension control system all the parameters are user-programmable.
