It all comes down to two simple gestures: placing the paper right, and getting the amount right. The Roller does the rest — a perfectly even cone, every time.
From the small size to the large King Size Batte, 5 reference sizes pre-calculated — plus the full range in between. A consistency you won't find anywhere else.
We keep only what's needed — for a finer cone and a cleaner finish. The elegance of a mastered gesture, French and Dutch style, made effortless by the Sizing Gauge.
The example below: a King Size Batte. The method is the same for all 5 sizes.
From opening the Roller to the finished cone put away: follow the full film with "⏯ All", or move scene by scene, at your own pace.
Every part is clickable — its info sheet opens, you close it, you pick up where you left off. And two see-through views show you the inside.
The King Size format is the size of the Batte I made by hand, one Christmas evening, and one I make again whenever it’s time to share with a partner, family, or friends. In fact, the machine was sized around a photo of it.
Three variables define it — the first two are set with the Sizing Gauge, the accessory included with your box, which acts as a template for both the paper length and the tip width:

As seen in the animation, here are the two rules for placing the paper — plus the one tip you pick up with practice. Master these points: an even cone, guaranteed.
Lay the paper flat, sticky edge parallel to the lines, sticky side up. Once aligned, the roll comes out perfect.
Only the corner opposite the sticky edge goes under the tip — no more, no less. A few tries, and the gesture becomes second nature.
The amount isn’t a rule, but a habit — just like by hand. The simulator gives you the right guide for every format.
To invent this machine, I started with my own gesture, repeated for almost twenty years. Filmed, observed, broken down, then recreated part by part. Four parts, four roles, one single mechanism — 12 months to make them fit together perfectly.
It all starts with a photographed and modeled cone: the shape, size, and layout of the rods are all calculated to match its curve exactly.
Hundreds of tests later, the result is a grip as steady as a thumb — one that never shakes. 3D note: printed vertically to come out perfectly round.
Without it, the rods would splay apart under pressure. Its spacing, calculated with precision, ensures even support — and lets you vary the amount of material for a slightly more generous cone.
It sets the angle — the one I used to apply by hand without realizing it. With its guide marks, the paper lands exactly under the sticky strip: a perfect cone, no creases.
It synchronizes all the rods: same speed, same pressure, even tightening. It's this combination of the four parts that delivers a finish impossible by hand — and found nowhere else, especially above 13 cm.
The "French-style" gesture adds a touch of elegance: you trim the excess before rolling, keeping only the right amount of paper. Result — a finer cone, a cleaner finish. The signature of connoisseurs, French and Dutch style.

And this is only the beginning: an even more complete technical Sizing Gauge is coming soon — find out more on the What's Next page.
The 3D animations show the principle. Here's my Roller filmed in the workshop — every technical gesture in close-up, with no material being rolled, to keep the focus on the tool.
To go further, I send out, on individual request, a full demonstration of about 12 minutes, showing the box unboxing followed by three consecutive builds (a classic cone, a King Size cone, and a King Size cone with a French-style trim) for each of my rollers. The ~12 minutes cover the unboxing and the 3 builds — making a single Batte is much faster.

Originally designed for people with a limited wrist or a disability, but also for the style.
I wanted you to be able to hold it in your hands, or close to it — so I modeled it all in 3D. Just below, the Original and the Premium: open them, turn them around, zoom in, and discover the accessories and features built into each.
The first one truly finished — the day every part finally came together. Patented internal geometry, with the Humidifier and the Large Tamper I wanted from the very start. Comes in the complete Original Box, always black.

The same invention, refined by my testers: three additions built for comfort — the Pusher, the Support Clamp, the magnets. You'll see them in action in the "Making a Batte" animation. Comes in 2 premium boxes, across four collections.
