**Mattress Tape Edge Machine (BWB-4B Auto-Flip, 300U Chain Stitch)**
This advanced mattress tape edge machine is designed for high-efficiency sewing of mattress edges. Compared to traditional models, the BWB-4B offers a more automated and intelligent operation. It features adjustable sewing head elevation, adjustable lifting height, and variable sewing speed. The work table is movable and controlled by a PLC system, making it easy to operate with artificial intelligence support.
During operation, the machine can automatically move the mattress, turn corners, and flip it over, significantly increasing productivity. The sewing head can automatically lower, reduce speed when turning corners, and return to normal after completing the corner, which greatly improves the quality of the stitching and solves common issues found in traditional corner sewing methods.
This machine can sew all four edges of a mattress continuously, then automatically move it to a set position for flipping. The entire process can be managed by just one operator, reducing labor intensity while boosting efficiency. It’s ideal for production lines that require fast and precise mattress finishing.
