Abstract: A needle thread feeding assembly in which the thread is positively fed at a desired stitch pitch while being clamped in between a presser roller and a drive roller, whose rotation is frictionally transmitted from a drive source. An encoder detects a predetermined amount of rotation and signals to restrict the drive roller, while allowing the drive shaft to continue rotating. A main-shaft-angle-detector detects predetermined angles adapted to operate the required stitch pitch and to start counting of pulses at the encoder. When a required number of pulses corresponding to the stitch-pitch is counted, the encoder signals to restrict the drive roller. Thus, the needle thread is positively and intermittently fed according to the stitch pitch.
