Main motor drives flyers Draft motor drives bottom rollers Winding motor drives bobbins Lifting motor drives bobbin rail A 10.4-inch, 2-language color function panel equipped with a Web browser improves interface ability. Connection to an internal or external network is possible for exchange of information or data, thereby expanding the capability of today’s spinning mills.

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 operation. The more this learning function is used, the greater the consistency in the roving packages. Learning function eliminates roving test runs and ensures consistent roving packages.
