Abstract
A sewing machine includes a plurality of needle bars for performing stitching with multiple needle threads. The needle threads have diameters, tenacity, and stretchability different from one another. Sewing parameters inherent to each of the needle threads are beforehand determined. The parameters are maximum sewing speed, thread breakage sensitivity, thread residual amount, needle-rotary hook meet angle, workpiece fabric feed timing, and feed pitch. A spindle motor, a thread cutting motor, a rotary hook drive motor, an X-axis motor, and a Y-axis motor are controlledly driven based on the selected parameters inherent to the just used needle thread.
