About this product

Product information from the supplier.

The GSC2602 series is a high-performance lockstitch sewing machine specifically engineered for the demanding requirements of FIBC (Flexible Intermediate Bulk Container), Jumbo Bag, and Bulk Bag manufacturing. Designed to replace traditional shuttle hook machines, this series integrates advanced engineering to handle heavy-duty materials with unmatched precision and stability, making it the industry standard for top and bottom feeding applications.

By incorporating a massive rotary hook—five times larger than standard versions—the GSC2602 significantly boosts bobbin capacity and reduces downtime. Whether you require a basic configuration, a pneumatic efficiency boost with the TD model, or an extended reach with the L25 long-arm version, this series provides a scalable solution for producing lifting belts, sports gear, safety belts, and heavy-duty tents.

Frequently Asked Questions

Q: What makes the GSC2602 better than a shuttle hook machine?

The GSC2602 features a rotary hook five times larger than standard shuttle hooks, increasing speed from 800 to 1200rpm and significantly reducing the frequency of bobbin changes.

Q: What is the difference between GSC2602 and GSC2602TD?

The GSC2602 is the basic function type. The GSC2602TD adds pneumatic presser foot lift and pneumatic reverse sewing to highly increase working efficiency.

Q: When should I choose the GSC2602-L25 model?

Choose the L25 model when you require a long arm (25 inches / 635mm) for special production items that require a larger working space.

Q: Can this machine sew materials other than FIBC bags?

Yes, it is widely used for sewing lifting belts, sports products, safety belts, tents, and other heavy-duty textile materials.

Q: What motor options are available for the GSC2602 series?

We offer 380V 3-phase clutch motors for basic models and high-efficiency servo motors (with needle position fixed-up function) for TD models.

Q: How does the feeding mechanism ensure stitch quality?

The precise top and bottom feeding design ensures that the upper and lower layers of heavy material do not shift, resulting in beautiful, professional stitches.
