Roving Frame FL200

A test run is normally required when roving new yarn types and yarn counts to determine the amount of increase in the bobbin diameter and input to the roving frame. The FL200 has completely eliminated this troublesome operation: in addition to an automatic calculation function for bobbin diameter increase based on the database inherited from the FL100, we have added a new control feature that successively predicts and corrects the actual amount of increase in bobbin diameter based on continuously accumulated operational data. As a result, actual conditions can be determined with greater accuracy, consistently providing the optimum package size with the optimal tension without the need to do a roving test. In addition, the database itself is automatically updated based on actual.
