Products Descriptions
If you run a jumbo bag factory, you must be troubled by traditional lockstitch bag sewing machines. They only sew forward and backward zigzag seams to attach lifting loops. When making X-box cross stitches where two loops overlap, your people have to lift and flip the whole heavy bag back and forth constantly. This repetitive heavy work drains your staff's energy, slows down the whole production line and leads to low daily output.
Our GA4670D and GA4670D-7 high-speed direct-drive FIBC lifting loop sewing machine with oversized rotary hooks eliminate this production pain point. Hold the handle to lift the presser foot, then shift bag fabrics freely in any angle to finish X-box and zigzag stitches effortlessly. This free-form sewing feature boosts daily output greatly, even for novice operators on your production line.
Two different models match your automation demands:
- GA4670D: Basic direct-drive version with upper and lower needle position
- GA4670D-7: Full-automatic direct-driven version
Both 360 degree free movement jumbo bag stitching machines share heavy-duty core specs: 6 times extra-large rotary hook, maximum 14mm stitch length, 16mm high foot lift and self-protection against skipped hooks or broken threads. This free movement fabric sewing machine for lifting loops fits all types of industrial big bags for worldwide FIBC and jumbo bag manufacturers.
