The DN-2 series represents the pinnacle of industrial sewing technology specifically engineered for the PP woven bag, paper bag, and jute bag manufacturing sectors. These high-performance sewing machine heads are meticulously designed to handle heavy-duty materials, providing seamless integration for seaming FIBC bag spout tubes and top skirt covers with unmatched precision and durability.
Offering a versatile range of configurations—including single needle, double needle, and specialized left-hand types—the DN-2 series ensures maximum flexibility for any production line. With the introduction of the U-type top and bottom feeding system and integrated pneumatic cutters for automated production lines, these machines deliver superior feeding performance and stable quality that meets the most demanding industrial standards.

For high-volume lines, we recommend the DN-2HSC or DN-2WC, which feature pneumatic cutters to automate the process and increase efficiency.
Yes, the DN-2 series is specifically designed for PP, paper, and jute. For extra-heavy materials, the U-type feeding (top and bottom) is highly recommended.
Yes, the original type is 100% exchangeable with Newlong machines, ensuring a hassle-free installation in your current production line.
The DN-2HS is a standard right-hand type sewing machine, whereas the DN-2LHS is the left-hand version to accommodate different factory workflow directions.
The DN-2W uses a 4-thread chain stitch, providing a much stronger and more reinforced seam, which is critical for heavy-duty jumbo bags (FIBC).
Auto-lubrication ensures that all critical moving parts are consistently oiled, reducing friction, preventing overheating, and significantly lowering maintenance costs.
