The PM-BNA Bonnell Spring Assembling Machine offers an efficient and reliable solution for producing mattress spring units. Designed with user-friendly controls, it requires only a single operator to manage material feeding and oversee the production process. This simplicity reduces labor costs while ensuring consistent output.
The machine supports adjustable spring diameters and heights within defined ranges, making it suitable for different mattress specifications. Its dual independent structure allows upper and lower rows to be assembled simultaneously, greatly improving productivity. Servo-driven wire feeding minimizes the risk of blockage, protects the cross wires, and extends the lifespan of pressure rollers.
A separate feeding unit controlled by variable frequency drives adapts speed to match spring shapes, ensuring smooth operation and improved machine stability. Automatic cross-wire cutting and in-line locking prevent wire displacement, maintaining the integrity of the spring unit during production.
To meet diverse customer needs, the PM-BNA can be equipped with different clamps and customized configurations, providing flexibility for manufacturers targeting various markets. Compact in design yet robust in performance, it delivers a reliable assembling solution for mattress manufacturers seeking higher efficiency and reduced downtime.
