Computerized 4 Thread Overlock Machine (BK Back Reverse System)

As a new generation of intelligent four-thread backstitching machine, it is specially designed for sewing underwear to ensure that the thread wrapping head is stable, effectively prevent sewing from cracking, and improve wearing comfort. Its core highlight is the use of step motor to accurately control trimming and presser foot lifting movements. It uses a one-for-two design and abandons the traditional electromagnet structure, which not only greatly reduces operating noise, but also significantly extends the service life of the machine. Equipped with a high-performance servo motor, the maximum speed can reach 7,000 rpm, achieving a double leap in speed and energy saving. Built-in 3 highly sensitive photoelectric sensors ensure that the thread trimming accuracy is controlled within 5 mm. This model uses innovative air suction technology to directly complete the wire wrapping head operation, completely bidding farewell to the traditional inefficient process of manual wire wrapping, and greatly improving production efficiency.
