<p>The present invention provides an automatic sewing machine which freely adjusts a wire tension in sewing. The automatic sewing machine (100) comprises the following components: a vertical movement mechanism of sewing needle; a feeding mechanism; a sewing wire adjusting device; an action control unit (1000) which performs positioning, wire tension exertion and sewing speed control based on the sewing data; and a temporarily stopping unit which temporarily stops the sewing action during a pattern sewing process. The invention is characterized in that: the automatic sewing machine is provided with a wire tension adjusting unit (74) which receives the input of related correction data of all needles for sewing a pattern for the thread tension defined in the sewing data while the sewing based on the sewing data (71a) is executed or is temporarily stopped. The action control unit performs action control with a following mode, namely the tension correction is not performed along with a tangential line or in the temporary stop; and the tension correction is started from a stitch after inputting the correction data with the wire tension which is corresponding with the correction data.</p> |
