Woven Bags, Laminating Bags, Non-Woven Fabrics
As part of modern heavy-duty bag production lines, the bag-making sewing machine head is a powerhouse specialist.
Core Features: Built for Strength and Durability
1. Specialized Stitching Thread:
· Exceptional Strength: The stitching itself is highly resilient, withstanding the immense impact forces and continuous vibration generated during bag filling, hoisting, handling, and transportation.
· Flexible elasticity: The stitching possesses elasticity, allowing minor adjustments to accommodate bag deformation and preventing breakage due to lack of flexibility.
· Slip-resistant: When thread ends are properly secured, the entire chain stitch resists unraveling from the ends.
· High Efficiency: Sewing speed is typically faster than lockstitch methods.
2. Robust Power and Heavy-Duty Construction
Heavy-Duty Frame: The machine body is constructed from thick cast iron for exceptional stability. This provides solid support when sewing multiple layers of thick woven fabric, minimizing machine vibration and ensuring consistent stitching.
· High-Power Motor: Equipped with a robust servo motor delivering substantial penetration force, effortlessly driving the specialized needle through up to 8 or even 10 layers of woven fabric (e.g., overlapping sections at bag bottoms and openings).
3. Automation and Efficiency Enhancement Features
Typically integrates multiple automated functions:
· Automatic Thread Trimming: Automatically cuts both top and bobbin threads upon stitch completion.
· Automatic Thread Trimming: Automatically guides cut thread ends to a suitable position for subsequent processing or aesthetic purposes.
· Automatic Backstitching/Reinforcement: Automatically performs several backstitches at the start and end of sewing to reinforce the seam and prevent fraying.
· Synchronization with Conveyor Systems: On automatic bag-making machines, it seamlessly coordinates with fabric feeding, hemming, cutting, and other devices to achieve fully automated production.
