When a used folding machine arrives at our workshop, the real work begins.

At first glance, everything may look fine.
But once the machine is inspected more closely, typical issues often appear.

---

common issues with used folding machines

In many cases, it’s not one big problem, but several smaller ones.

Faulty sensors, unevenly worn folding rollers, or missing dampers are all common findings.
These are normal signs of wear and usage over time.

None of this is unusual.
In fact, it’s part of working with used machines.

---

why inspection matters

Every machine needs to be checked carefully before it is ready for production again.

Small issues can have a big impact on performance.
A faulty sensor can interrupt the workflow, worn rollers affect folding quality, and missing components make operation more difficult.

Identifying these points early ensures that the machine can run reliably later.

---

experience makes the difference

The key is not just finding problems, but knowing where to look.

With experience, typical issues can be identified quickly and solved efficiently.
This reduces downtime and ensures consistent performance.

---

preparing machines for their next job

Before a machine leaves our workshop, it is checked and evaluated.

Depending on the customer’s needs, machines can be delivered in their current condition or prepared further.

The goal is always the same:
a machine that fits the production and runs reliably.

---

conclusion

Used folding machines always come with a history.

Understanding that history and knowing what to check is essential to get the best performance out of them.

In the end, it’s not about avoiding wear –
it’s about handling it the right way.

Folding rollers are essential for achieving clean and precise folds.
The challenge is that wear is often not immediately visible.

In practice, a typical pattern appears. If the same format is used over a long period of time, the rollers do not wear evenly. The area where folding happens constantly is used much more, while other areas remain almost untouched.

One clear sign is the difference in material thickness towards the metal core. In heavily used areas, less material remains, which directly affects folding quality. Results become less consistent, and the machine is put under more stress.

Not every sign of wear requires immediate replacement. However, once quality starts to drop and consistent results are no longer possible, the rollers should be replaced.

New folding rollers are an investment, but they ensure that the machine runs smoothly and reliably again.

---

conclusion

Uneven wear on folding rollers is a common issue, especially when running the same formats continuously. Regular checks and timely action help avoid quality problems and unnecessary machine wear.

In daily production, small mechanical issues can quickly turn into real problems.

A typical example:
The arm of a folding machine becomes difficult to move.

At first glance, this might seem like wear, stiffness, or a general mechanical issue.
But in many cases, the cause is much simpler.

A Common Problem in Folding Machines

In our workshop, we recently had exactly this situation.

The arm of a folding machine could hardly be moved.
Operating it required much more force than usual.

This is not just inconvenient – it also slows down production and can lead to further wear over time.

The Cause: A Missing Damper

With experience, certain problems become very clear.

In this case, the issue was identified immediately:
A missing damper.

Dampers play an important role in many folding machines.
They ensure smooth and controlled movement of mechanical parts, such as arms or units.

If a damper is missing or defective, the movement becomes stiff, uncontrolled, or difficult.

The Solution

The fix was simple but effective.

A new damper was installed, and immediately the difference was noticeable.

The arm could be moved smoothly again, without force or resistance.
The machine was back to normal operation within a short time.

Why This Matters

Issues like this are more common than many operators think.

A missing or defective damper may seem like a small detail, but it has a direct impact on:

• ease of operation
• machine wear
• production efficiency

Ignoring such problems can lead to bigger mechanical issues over time.

The Value of Experience

What made the difference here was not a complex repair –
but knowing where to look.

Recognizing typical issues quickly saves time, reduces downtime, and keeps production running.

Conclusion

If a folding machine becomes difficult to operate,
it’s not always a major defect.

Sometimes, it’s just a small missing component like a damper.

Checking these details can make a big difference in performance and usability.

Practical Tip

If parts of your machine suddenly become hard to move,
always check for missing or worn mechanical components first.

Often, the solution is simpler than expected.

In perfect binding, the choice of adhesive has a major impact on quality, durability, and production efficiency.
The two most important systems are EVA (hotmelt) and PUR adhesive.

But what are the differences – and which one is the right choice for your production?

What is EVA Glue (Hotmelt)?

EVA is the traditional hotmelt adhesive used in print finishing.
The glue is heated, applied to the spine, and hardens as it cools down.

It is a well-established standard, especially in offset printing.

Key characteristics of EVA:

EVA is easy to handle and cost-effective.
The adhesive remains in the machine and can be continuously refilled.
In most cases, there is no need to dispose of it at the end of the day.

EVA works best with uncoated papers and standard production jobs.

What is PUR Adhesive?

PUR (polyurethane) is a reactive adhesive that cures through a chemical reaction with moisture in the air.

Unlike EVA, it does not simply harden by cooling, but by reacting chemically – which results in a much stronger bond.

Key characteristics of PUR:

PUR offers very high bonding strength and creates durable, flexible bindings.
It is especially suitable for coated, laminated, or glossy papers.

Special Considerations When Using PUR

In daily production, PUR requires a different approach than EVA.

Since PUR reacts with air, it cannot simply remain in the system.
Any remaining adhesive must be disposed of or the system must be properly sealed.

Components that come into contact with PUR are specially coated to prevent adhesion.

As a result, cleaning and maintenance requirements are higher compared to EVA.

The Key Differences

EVA is the simpler solution for everyday use.
It stays in the machine, is easy to refill, and requires minimal maintenance.

PUR, on the other hand, requires more attention.
It reacts with air, cannot be reused, and demands careful handling and cleaning.

However, PUR delivers significantly stronger bonding and performs reliably even with difficult materials.

When Should You Use EVA or PUR?

EVA is ideal for standard production, especially in offset printing and with uncoated papers.
If ease of use and cost-efficiency are priorities, EVA is the right choice.

PUR is the better option for more demanding applications.
It is the preferred solution for coated, laminated, or digitally printed materials where strong and durable binding is essential.

Conclusion: The Adhesive Makes the Difference

Both EVA and PUR have their place in perfect binding.

EVA stands for simplicity, reliability, and efficiency.
PUR delivers maximum performance and bonding strength – even under challenging conditions.

In practice, many binding issues are not caused by the machine itself,
but by choosing or handling the wrong adhesive.

Practical Tip

When working with PUR, proper cleaning and correct handling are essential.
With EVA, consistent temperature and stable processing are the key factors.
