The vest bag bag-making machine belongs to the category of fully automatic non-woven fabric bag-making machines. It is mainly used for producing non-woven fabric packaging products such as vest bags, handbags, and edge-inserted bags, and is compatible with non-woven fabric materials ranging from 30 to 120 g/m². The common models of this equipment include NK-GW2012, WZDJ-B, etc. They are produced by manufacturers such as Zhejiang Wenzhou Ruizhi and Zhengwei Machinery. The core components adopt an L-shaped structural design, and the overall size of the machine is approximately 5.5×3.5×1.6 meters.

The equipment is equipped with five sets of ultrasonic bonding systems, integrating PLC program control, stepless variable frequency speed regulation and touch screen operating system. It supports stepwise fixed-length and photoelectric tracking technology to control the cutting accuracy, and the production speed can reach 50-70 pieces per minute. The modular design simplifies the process of replacing the pressing wheels, and it can adapt to different bag types by adjusting the cutting edge and sewing effect. It is equipped with material shortage protection, deviation correction system and leftover material recovery device. The automated process covers folding, punching, counting and other procedures, and only requires 1-2 people to operate.

The patented technology features a folding mechanism that employs multiple cylinder linkage locking plates and buffer springs, which helps prevent damage to the bag body. Some models adopt a waste-free heat sealing and edge insertion device, reducing material waste through layer-by-layer edge pressing technology. The equipment is also equipped with a compression-type debris collection system and anti-sticking panels, enhancing cleaning efficiency.
