DS-9CW 2-Needle 4-Thead Bag Closing Machine Head

Look for a heavy-duty bag closing solution that delivers unbeatable sealing firmness, prevents material leakage, and keeps up with high-volume production? The DS-9CW 2-needle 4-thread bag closing machine is a professional 2-needle 4-thread high-speed model, engineered with automatic thread cutting-perfect for sealing thick, heavy-duty bags across industries that demand reliability and efficiency.​

Crafted with a dual-needle and dual-looper design, this machine creates two independent, parallel rows of stitches. With a fixed 6mm distance between the two needles, the dual-stitch structure forms a reinforced seal that drastically enhances packaging firmness-ideal for heavy, bulky bags or materials prone to leakage. Running at an impressive working speed, it outperforms standard single-needle models, ensuring your production line stays productive even during peak hours.​

Built for long-term, continuous use, the DS-9CW features an advanced oil bath lubrication system that evenly coats all internal moving parts. This not only reduces friction and minimizes operating noise (creating a quieter workshop environment) but also significantly extends the machine's service life-cutting down on maintenance frequency and replacement costs over time. The integrated automatic thread cutter adds convenience: after sewing the each bag, it trims threads cleanly in one step, eliminating extra manual work and streamlining your packaging workflow.​

Equivalent to the trusted Newlong DS-9CW, this automatic thread cutter bag closing machine is designed for seamless integration into automatic bagging lines. It can be unit with sewing pedestals and conveyors of various lengths to match your production setup, adapting to different bag sizes and processing needs. Versatile and robust, it excels at stitching filled paper bags, PP woven bags, cloth bags, jute sacks, and other heavy-duty packaging-making it a go-to choice for industries like agriculture, construction, chemical, and bulk material handling.​

Whether you're packaging granular fertilizers, heavy construction materials, or bulk agricultural products, the DS-9CW PP woven bag heavy-duty closing machine delivers the leak-proof, durable seals you need. Its combination of high speed, reinforced stitching, low maintenance, and compatibility with automatic lines makes it an indispensable asset for boosting efficiency and ensuring product integrity during storage and transportation.

1. What stitch types do PACKSTAR bag closing machines adopt for bag sealing?
A: Our bag closing machines mainly use durable chain stitch, including single-thread, double-thread and four-thread styles. The chain stitch features high tensile strength, not easy to unravel even under heavy load, perfectly suited for long-term stacking and transportation of filled industrial bags.
2. What kinds of packaging bags can PACKSTAR full-series bag closing machines sew?
A: All models adapt to PP woven bags, plastic sacks, paper bags, jute bags and composite lined bags. High-speed and double/four-thread models can handle thickened multi-layer bags, while standard single needle models meet the sealing demands of conventional light and medium packaging bags.
3. How to improve the overall efficiency of the bag closing production line?
A: Match high-speed bag closing machines with synchronous-speed bag infeed devices. Regularly maintain the equipment to reduce downtime. Set reasonable stitch length and running speed according to bag materials to avoid repeated rework caused by unqualified sealing.

4. How about the packaging and transportation of that machine?
A: All the machines are packed in standard export cartons or wooden packaging boxes to prevent damage during transportation.
