Equipped with a differential feed to permit the gathering of fabrics for creating ruffles, for example, and for sewing knits without them stretching, this two-needle machine sews six kinds of stitches with three or four threads and permits quick, easy stitching, trimming, and overcasting in a single operation. It provides convenience, speed (up to 1,300 stitches per minute), and the reliability of the Singer name. Available stitch functions include the three-thread overlock; the three-thread, wrapped-edge overlock; the four-thread mock-safety stitch; flatlock; blind hem; and rolled hem. Conversion from normal overedging to rolled hemming can be accomplished without changing the throat plate.
Color-coded threading, adjustable stitch width (ranging from 3 to 6.7 mm), adjustable stitch length (from 2 to 4 mm), a stitch-length control dial, adjustable differential feed, presser-foot adjustment, and tension-adjustment dials for all four threads offer exceptional flexibility and control. Simply removing the cloth plate converts the machine for free-arm work. Singer's illustrated, step-by-step instruction booklet that accompanies the machine is invaluable. The machine comes with a 25-year warranty against defects on the sewing machine head; a five-year warranty on electrical and electronic components; and a one-year warranty against defects on parts and adjustments. --Fred Brack
