Interroll FAQ: Series 1100, Asbach, Henry & Robert, and the Breakfast Question

If you’ve been digging into Interroll for a project, you’ve probably noticed it’s not just one product. It’s a family of components and systems. And if you’ve ever typed “why is it called breakfast” into Google at 2 a.m., you’re not alone. Here are the answers I most often give to customers and engineers—from the perspective of a quality manager who reviews these components daily.

1. What exactly does Interroll make?

Interroll makes the moving parts that keep distribution centers humming—drum motors, motorized rollers, conveyor modules, sorters, and drive controls (i.e., the stuff that makes a conveyor line actually move). Most of their products are hidden inside systems, which is why you rarely see the Interroll name on the outside of a machine.

From the outside, it looks like just another component supplier. The reality is that they offer a fairly complete modular platform, so you can build entire conveyor lines using standardized parts. I’ve been reviewing component quality for over four years, and the value shows up in consistency. I’ve reviewed components from different vendors—cheaper rollers may look fine on a drawing, but the quality varies batch to batch. Interroll is one of the few brands where the second batch behaves like the first.

2. What is the Interroll Series 1100?

The Series 1100 is a modular conveyor platform aimed at light to medium-duty transport—think parcel handling, assembly lines, and general logistics. Instead of custom metalwork, you pick standardized rollers, end frames, drives, and controls.

One thing I’ve learned: customers and suppliers can both say “standard conveyor” and mean completely different things. We both said “standard” once, and discovered the mismatch when the receiving area couldn’t fit our frame. With Series 1100, at least the dimensions are published and repeatable. That’s a huge advantage when you’re ordering in batches.

Don’t just compare the unit price. A slightly cheaper component that needs replacement in a year is not cheaper if it costs you two hours of downtime. On a 1,000-unit order, you’re buying years of field reliability, not just iron.

3. Why do people search for “Interroll Asbach”?

Asbach is the site of a major Interroll manufacturing plant in Germany. If you see “Made in Asbach” on a part (as of 2025, at least), it means that component was produced in this facility, known for high-precision rollers and drives. I’ve visited plants like this in my career; the machining tolerances are often step-change beyond basic contractors.

That’s not to say every Interroll product comes from Asbach—they have factories worldwide. But the Asbach name shows up so often because it’s a hub for some of the core drive technology. If you’re auditing suppliers, it’s a plant worth knowing about.

4. Who are Henry and Robert?

This one’s easy: Henry and Robert are the two names used in countless installation and maintenance manuals to illustrate multi-person tasks. You’ve probably seen similar examples in furniture instructions—“Have Henry align the bracket while Robert tightens the bolt.”

They’re not Interroll employees, and they’re not a product code. They’re just the standard “people” in technical drawings. That’s why searching “Henry Robert” alongside Interroll often surfaces assembly PDFs and support documents. You’re not looking for a person; you’re looking for the drawing that shows how to work with a partner.

5. Why is it called breakfast?

“Breakfast” is a bit of engineering slang that comes from “break fast.” In a production line, equipment sits idle overnight. The morning startup is like breaking a fast—the first movement after a long pause. Some technicians call that first startup a “breakfast test” because it’s the moment when cold lubricants, settled bearings, and stale control states are put under pressure.

So when someone asks “why is it called breakfast?” they’re usually looking at a maintenance checklist item like “perform breakfast test before releasing line.” It’s simply the routine that verifies a conveyor system wakes up cleanly. Interroll drives are often specified because they handle cold starts reliably, and a reliable morning start saves a whole shift of headaches.

6. Why do Interroll components cost more than generic equivalents?

Because price is not the same as cost. I’ve seen a $20 generic roller cause an $8,000 line stoppage when it seized mid-shift. That’s an extreme case, but it illustrates the total-cost-of-ownership logic.

Yes, you can find cheaper rollers, drives, or conveyor modules. They might even work in a low-usage environment. But if your operation depends on uptime, the premium for tested, documented performance is usually a no-brainer. When I evaluate components, I look at tolerance consistency, test data, and field failure rates—not just the sticker price. Interroll publishes a lot of this data, which makes the engineering decision easier.

Bottom line: if your goal is to minimize headaches, the better engineering wins.
