If you’ve never seen a Heidelberg Windmill in operation, you’re missing one of the most remarkable machines ever built for the printing industry. Although its official name is the Heidelberg Original Platen Press, printers around the world simply call it the Heidelberg Windmill because of its unique rotating arms that feed and deliver each sheet of paper. As the gripper arms spin, they resemble the blades of a windmill, giving the press its famous nickname.
At Classic Impressions, our Heidelberg wasn’t just an interesting piece of machinery—it helped us improve turnaround times, bring finishing work in-house, and better serve our customers.
Watch Our Heidelberg Windmill Press Running a Numbering Job
Before the Heidelberg
Long before we owned a Heidelberg, we relied on a Chandler & Price hand-fed letterpress for numbering, perforating, scoring, and the occasional die-cutting job.
I learned to operate a Chandler & Price while working after school as a teenager for Philip and Vera Page at Page Printing, later known as Creative Imprint. Those years taught me the fundamentals of traditional letterpress printing and gave me an appreciation for the craftsmanship required to produce quality work.
When Jill and I started our own business, we purchased a used Chandler & Price from an old Atlanta letterpress shop. At the time we were working out of our garage, and the press became an important part of our growing business. Most of the work consisted of numbering carbonless forms, adding perforations, scoring fold lines, and occasionally doing simple die-cutting.
Outgrowing the Hand Press
Around 2005, we moved from our Canton Road location to our Bells Ferry Road shop. Unfortunately, there wasn’t enough room to move the Chandler & Price with us.
By then, customer demand for numbering, perforating, and scoring had grown so much that we were outsourcing those jobs to a local bindery. Looking back, I regret scrapping the Chandler & Price because of its historical value, but at the time we were focused on keeping our business moving forward.
As our workload continued to increase, it became clear that bringing those services back in-house would improve both productivity and customer turnaround times.
Finding Our Heidelberg Windmill
Around 2011 or 2012, we had the opportunity to purchase a Heidelberg 10×15 Windmill from one of our vendors. He had an extra machine sitting unused in his warehouse.
Ironically, by selling us the press, he was giving up some of the finishing work we had been sending him. Instead of protecting his own business, he chose to help ours grow. I’ve never forgotten that generosity.
The press was in excellent condition. After moving it into our shop and running the electrical service, it was ready to work. I hired professionals to move it because a Heidelberg weighs several thousand pounds, and I wasn’t about to risk damaging either the machine or the building.
Why It’s Called the Windmill
People often ask why these presses are called “Windmills.”
The answer is simple. Two rotating gripper arms continuously pick up each sheet, carry it into the press, and deliver the finished sheet to the output pile. Watching those arms rotate is like watching the blades of a windmill turn.
The motion is smooth, precise, and surprisingly mesmerizing.
Learning the Heidelberg
Although I had never owned a Heidelberg Windmill before, I had previously operated a Heidelberg KORD offset press, which used a similar sheet-feeding system. Because I’m fairly mechanical by nature, learning the Windmill wasn’t particularly difficult.
One thing I’ll never forget is its sound.
The best way I can describe it is like someone taking a deep breath and letting it out with a powerful swooshing sound. Every Heidelberg has its own rhythm, and once you’ve heard one run, it’s a sound you’ll recognize forever.
I never bolted ours to the floor, so I couldn’t run it at maximum speed. If I pushed it too hard, the machine would actually begin rocking back and forth. That was enough to convince me to slow it down!
How Mechanical Numbering Worked
One of the primary reasons we purchased the Heidelberg was for sequential numbering.
Before today’s digital technology, forms were numbered using mechanical numbering heads. These small devices automatically advanced to the next number every time the press cycled.
Setting up a numbering job required careful planning.
First, I measured exactly where the number needed to appear on the printed form. Then I built the chase using furniture and quoins to position the numbering head correctly before locking everything securely into place.
Sometimes I ran two numbering heads on the same job. That required a little math to make sure both heads advanced in the correct sequence. Another interesting detail was that all of the numbers had to be set in reverse so they printed correctly on the paper.
Like many printers, I learned a few lessons the hard way.
One day I failed to lock the chase securely. During the press run, everything shifted, and one of my numbering heads was crushed beyond repair. I kept that damaged numbering head for years as a reminder to always double-check the lockup before starting the press.
A Better Way to Work
Compared to the old hand-fed Chandler & Price, the Heidelberg dramatically improved our efficiency.
Once the machine was properly set up, it could run automatically while I worked on other projects around the shop. If it ran out of paper, it stopped. Misfeeds were uncommon once everything was adjusted correctly.
The Heidelberg allowed us to produce numbering, perforating, and scoring jobs faster while giving our customers shorter turnaround times.
Looking back, purchasing that machine was absolutely the right decision for our business.
From Mechanical Numbering to Digital Printing
Today, we accomplish the same task using variable-data printing.
Instead of mechanical numbering heads, we generate sequential numbers directly from a CSV database. Whether we’re producing single-sheet forms or multi-part carbonless forms, every number is created digitally using our production printing equipment.
Modern digital printing eliminates liquid numbering ink, reduces setup time, and provides tremendous flexibility for short-run work.
While mechanical numbering still has a place in certain long-run applications, digital variable-data printing has become the preferred solution for most of our customers.
Saying Goodbye
Our Heidelberg served Classic Impressions well for several years.
When we relocated to our embroidery facility, the press went into storage and was never put back into production. Eventually, when we moved again in 2026, it became clear that it was time for the machine to find a new home.
Rather than see it scrapped, I gave it to a gentleman who collects and preserves vintage letterpress equipment for educational purposes. The last time I saw it, it was waiting alongside several other historic presses for restoration.
I like to think it’s still helping people appreciate the craftsmanship and engineering that made these machines legendary.
Looking Back
Do I miss the Heidelberg?
In some ways, yes.
It was an enjoyable machine to operate, and watching it run was always satisfying.
But printing technology continues to evolve.
The Heidelberg taught me that every generation builds on the innovations of the people who came before. The engineers who designed these presses pushed mechanical engineering to remarkable levels of precision, and many of their machines are still operating more than seventy years later.
Today’s equipment is faster, cleaner, and far more versatile. Yet the Heidelberg Windmill represents an era when mechanical ingenuity solved problems that today are handled by software and computers.
The technology has changed.
The commitment to quality craftsmanship has not.
At Classic Impressions, that commitment continues today—whether we’re numbering forms with modern variable-data printing or producing the next generation of printed products for our customers.
