The gesture of the hand.
Only better, every time.
It all comes down to two simple moves: place the paper well, dose the material well. The Roller does the rest — a regular cone, guaranteed.
From the small format to the large King Size Batte, 5 reference formats are pre-calculated — plus everything in between. A consistency you'll find nowhere else.
Keep only what's needed — for a purer taste and a smoother draw. The elegance of a mastered gesture, French and Dutch style, made easy by the Sizing Gauge.
The example below: a King Size Batte. The method is the same for all 5 formats.
Making a Batte, step by step
From opening the Roller to the finished cone put away: watch the full film with “⏯ All”, or move scene by scene, at your own pace.
Every part is clickable — its info opens, you close it, you carry on. And two see-through views show you the inside.
All about the King Size format
The King Size is the format of the Batte I made by hand one Christmas evening — a story I tell on the (French) history page — and the one I make again whenever I share with a partner, family or friends. The machine was actually sized around a photo of it.
Three variables define it — the first two are set with the Sizing Gauge, the accessory included in your box, which acts as a template for both the paper length and the tip width:
- Its length: 13.23 cm (the maximum of the Sizing Gauge)
- Its tip width: 6 mm (Size 1 on the Sizing Gauge)
- Its amount of material: volume 1.75 ≈ 1.16 g — indicative, to fine-tune with the simulator depending on your material
The 2 rules + one tip.
Seen in the animation, here are the two rules for placing the paper — and the one tip that comes with practice. Master these and a regular cone is guaranteed.
The sticky edge, parallel to the lines.
Lay the paper flat, sticky edge parallel to the lines, sticky side up. Aligned properly, the roll is perfect.


Only the corner under the tip.
Only the corner opposite the sticky edge goes under the tip — no more, no less. A few tries and the move is yours.



Take your time.
The amount of material isn't a rule but a habit — just like by hand. The simulator gives you the right reference for each format.

How I designed these parts
To invent this machine, I started from 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 from a cone photographed then modelled: the shape, size and layout of the rods are all calculated to hug its curve exactly.
Hundreds of trials later, the result is a grip as sure as a thumb — one that never trembles. 3D note: printed vertically to come out perfectly round.
Without it, the rods would spread apart under pressure. Their spacing, calculated to the millimetre, ensures an even hold — and lets you vary the material for a slightly fuller cone.
It sets the angle — the one I used to apply by hand without knowing it. With its markers, the paper presents itself right under the sticky strip: a perfect cone, no crease.
It synchronises 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 beyond 13 cm.
Keep only what's needed.
Before, not after.
The “French method” adds a touch of elegance: you remove the excess before rolling, to keep only the right paper. The result — a purer taste, a smoother draw. The connoisseurs' signature, French and Dutch.
And this is only the beginning: a technical ruler, more complete still, is coming soon.
La Batte in real conditions
The 3D animations show the principle. Here is my Roller filmed in the workshop — every technical move close-up, without material to roll, to stay focused on the tool.
Request a full walkthrough
To go further, on individual request I send a full walkthrough of about 12 minutes: the unboxing, then three cones made in a row (classic, King Size, and King Size with the French-method trim) for each of my rollers. The ~12 minutes cover the unboxing and the 3 cones — making a single Batte is much quicker.
