Binding machines for tree nurseries: rope, elastic or wire?

Introduction

In tree nurseries, binding plants and shrubs is a daily activity. From rose plants to ornamental shrubs — bundling is essential to transport, process or sell products properly. An efficient and reliable binding machine can save a lot of time and manual work.

In this article, we explain which types of binding machines exist, what the differences are between string, elastic and wire binders, and which type is most suitable for tree nurseries. We use the Rasspe binding machine as a practical example of a string binder, as it is widely used in many nurseries.

Why binding is so important in tree nurseries

Bundling plants may seem simple, but in practice it requires precision:

• The bundle must be strong enough not to loosen.
• The binding must not damage the product.
• The process must be fast and consistent.

A good binding machine helps strike the right balance between speed, strength and product protection.

Types of binding machines in practice

3.1 Elastic binding machines

Machines that work with elastic (such as many models from Cyklop, ARC and Bercomex) are widely used in the flower sector and for lighter products.

Advantages:

• Fast and easy to use.
• Elastic stretches, reducing the risk of damaging delicate stems.

Disadvantages:

• Less suitable for heavier or woody crops.
• Bundles may loosen over time.

3.2 Wire binding machines

Wire binders — using thin iron wire — are primarily used for heavier crops or technical applications.

Advantages:

• Extremely strong binding.
• Suitable for bundles that need long-term storage or transport.

Disadvantages:

• Higher risk of damaging plant material.
• Less flexible in settings and material choice.

3.3 String binding machines (such as Rasspe)

Binding machines that work with string combine the best of both worlds: they deliver a strong binding while still being gentle on the product.

A well-known example in the nursery industry is the Rasspe binding machine. These machines use a single-knot tying head, a technique also used in agricultural balers, so its reliability is well proven.

This creates a real knot instead of a loop, preventing bundles from shifting.

“The advantage of the Rasspe is that every knot is tied with the exact same tension. That makes the work not only faster, but also much neater.” — Technical Specialist, Duijndam Machines

The Rasspe RS 312D is now available new from us. Read everything about this binding machine here.

Advantages of string binders:

• Tight, durable bindings.
• Suitable for rose plants, ornamental shrubs and other woody crops.
• Adjustable tension: consistently tight bundles.
• Suitable for indoor and outdoor use, often with 3-point attachment for tractors.

In nurseries where sturdy products are processed, a string binder often offers the most reliable solution.

4. What to consider when choosing a binding machine?

a. Type of product

• Soft stems or flowers: elastic is often sufficient.
• Woody plants or shrubs: string or wire offers more strength.

b. Workplace and environment

• Indoors or in the shed: stationary binding machines are convenient.
• In the field: choose a mobile machine with 3-point attachment or a wheeled frame.

c. Maintenance and durability

Pay attention to the drive (e.g. V-belt drive for reduced noise) and the quality of the knotting head. A well-maintained knotting mechanism prevents irregular bindings and downtime.

5. Practical tips

• Adjust knot tension to the product: tight for shrubs, looser for softer plants.
• Use the correct string thickness and quality to prevent knotting issues.
• Regularly check the machine’s knives and guides — dirt and wear affect binding performance.
• Combine with a conveyor belt or collection table for an ergonomic workspace and higher processing capacity.

7. Conclusion

Binding machines are indispensable in modern tree nurseries. The choice between string, elastic or wire depends on the crop type, desired binding strength and working environment. String binders — such as Rasspe models — offer the best combination of strength, precision and durability for sturdy products.

By choosing the right machine and maintaining it properly, growers save time every day, improve bundle quality and extend the lifespan of their products.
