Zusammenfassung: | The electronic sewing machine in the invention comprises a low speed command switch and a control device. The operator only executes on operation to the low speed command switch at the parts of easy to roll up when sewing the fabrics. When the low speed command switch is on, the control device drives the sewing machine motor or sewing machine motor, X-axis drive mechanism and Y-axis drive mechanism at a second speed. The second speed is lower than the first speed of normal sewing; the needle, take-up-lever and shuttle driven by the sewing machine act by the speed lower than the normal sewing. The operator uses pressing piece to press the fabric, thereby continuing the sewing. The invention provides an electronic sewing machine preventing the rolling up of the fabric to improve the quality of the product and not reduce the efficiency of sewing work. |
