ULTIMA UL-0617DD-4 – single-needle lockstitch machine with triple feed and automatic functions for heavy-duty sewing

ULTIMA UL-0617DD-4 is an industrial single-needle lockstitch sewing machine with triple feed, designed for sewing medium and heavy materials. It is suitable for automotive and furniture upholstery, leather goods, bags, covers, tents, tarpaulins and other products made from thick or multi-layered materials.

The triple feeding system combines bottom feed, needle feed and a walking foot to provide smooth and consistent transport of all material layers. This helps prevent individual layers from shifting during sewing and makes it easier to handle thick, slippery and multi-layered materials. The machine is also equipped with a large hook, allowing the use of a larger bobbin and reducing the frequency of bobbin changes.

ULTIMA UL-0617DD-4 features an energy-efficient Direct Drive servo motor integrated into the machine head. The direct drive system provides quiet operation, fast response to pedal movement and precise sewing speed control. An integrated control panel provides convenient access to the machine's automatic functions.

Automatic thread trimming, presser foot lifting, backtacking and needle positioning reduce manual operations and improve productivity. The combination of a powerful feeding system and automatic functions makes the UL-0617DD-4 particularly suitable for production environments requiring efficient sewing of heavier materials.
