Abstract
A sewing machine is disclosed which includes at least one regulatable operating instrumentality, such as, for example, an adjustable needle thread tensioner. Means are provided for generating signals indicative of different parameters which affect the ultimate overall stitch, such as, for example, fabric thickness at the seam, thread type, and pattern type. A central processor is provided with an algorithm for controlling the thread tension so as to maintain uniform stitch quality as a function of the different parameters.
