<p>PURPOSE:To provide a draw false-twister capable of sensitively detecting the variation of tension and having a margin in evaluation period. CONSTITUTION:This draw false-twister is provided with a sampling means 15 for sampling measured tension data at a prescribed time interval (t), a memory 20 for holding the sampled tension data for the latest prescribed time Ts (min) and an evaluation means 17 for evaluating the tension data of the memory 20 at a prescribed interval T longer than Ts and generating an alarm data when the evaluation result is out of a control limit.</p> |
