This needle feed machine incorporates a link type needle feed mechanism, link tread take up and rotating hook to form a high quality lock stitch. The arm shaft and hook are driven by bevel gears. The dial adjusted stitch regulator together with the lever type reverse feeding mechanism and automatic lubrication ensure smooth sewing at any speed and in either direction. The needle feed mechanism allows for a more stable sewing environment thus preventing material layers from shifting or slipping on one another. It is used on such material as silk, nylon, light plastics, and all types of synthetic fabrics. Model GC0518-A-D is also available as an automatic underbedtrimming machine in which additional functions come as standard equipment.
