Quelles sont les différences entre les machines à ressorts Bonnell, à poche et continues ?

Mattress spring machines may look similar on the surface, but the types of springs they produce—Bonnell, pocket, or continuous—are very different in function, structure, and performance.

The main differences lie in spring shape, motion isolation, machine complexity, and cost efficiency. Each machine type serves a different market need.

Understanding these differences helps buyers select the right machinery for their target customers and production goals.

What Does Each Machine Type Actually Produce?

Each type of spring system delivers a unique sleeping experience and manufacturing process.

Here’s a side-by-side comparison:

Each machine type is designed specifically to produce one of the above structures with precision and efficiency.

Bonnell spring machines produce hourglass-shaped coils that are then connected together using spiral wires. This design is traditional and still popular in emerging markets.

Key machine features:

• High-speed coiling and knotting
• Spiral wire insertion system
• Robust mechanical construction

Advantages:

• Lower machine cost
• High output speed
• Simple to maintain

Disadvantages:

• Poor motion isolation
• Shorter product life
• Louder in use

Bonnell spring units are ideal for entry-level mattresses or for use in commercial/hospitality projects where price and firmness matter most.

Your choice depends on your production goals. If you’re focusing on budget markets, Bonnell or continuous machines are efficient. For premium mattress brands, pocket spring lines are essential.

What Type of Comfort Does Each Machine Enable?

Comfort is the ultimate customer goal, and the spring structure plays a big role.

Bonnell Springs

• Feel: Firm and uniform
• cURL Too many subrequests. Back sleepers, budget buyers
• Weakness: Poor pressure relief and motion isolation

Ressorts à poche

• Feel: Responsive and contouring
• cURL Too many subrequests. Side sleepers, couples
• Weakness: Higher cost per unit

Continuous Springs

• Feel: Uniform and supportive
• cURL Too many subrequests. Children’s beds, basic hotel use
• Weakness: Lacks adaptive feel of pocket coils

How Does Maintenance Compare?

• Bonnell machines: Easy to maintain with basic mechanical knowledge. Less electronic dependence.
• Pocket machines: Require regular ultrasonic module cleaning and fabric tension checks. More moving parts.
• Continuous machines: Moderate maintenance; mostly focused on wire feeding and cutting wear.

Conclusion

Bonnell, pocket, and continuous spring machines each have unique production goals. If you want to compete in mid- to high-end mattress markets, pocket spring machines are a must. If you serve bulk or entry-level needs, Bonnell and continuous machines offer speed and simplicity.

Choosing the right machine means balancing product quality, production cost, and market demand.
