Superior Precision and Intelligent Automation
The SP-F221 is an advanced automation system that combines speed, accuracy, and stability in sleeve hem and hem ribbing operations.
Thanks to its compact design, it takes up little space and operates with the same precision on thin, medium, or high-elastic fabrics.
Simple settings allow for easy switching between different fabric types, and production continues without the need for size adjustments when changing models.
Performance and Quality Advantages
The machine features three rib placement shelves. Each shelf can accommodate 60–80 ribs and, with its cyclical operation, ensures uninterrupted production.
The automatic rib insertion function, working in conjunction with the rib tension mechanism and adjustment system, automatically aligns and straightens the rib during feeding.
This ensures a smooth, constant, and error-free rib feed throughout the seam.
The automatic reverse stitch system maintains a consistent stitch direction, ensuring an aesthetic result with the same stitch direction across all pieces.
Once the seam is complete, the mechanical take-up arm automatically transfers the product to the receiving area.
Superior Productivity
The SP-F221 significantly reduces production time by performing automatic rib feeding, reverse sewing, and gathering steps in a single cycle.
Operator intervention is minimal; the system operates autonomously, saving time, labor, and costs on production lines.
One operator can manage two machines simultaneously—meaning twice the productivity.
Applications
The SP-F221 is designed for sleeve hem and hem ribbing on products such as t-shirts, sweatshirts, and thermal underwear.
With its structure that adapts to different fabric types and its fully automatic control system, it delivers high quality and speed in both small workshops and industrial production lines.
