How Are Pre-Roll Cones Made?
Empty cones start as paper bobbins. The plant cuts a trapezoid, inserts a tip, wraps and seals the leaf, dries the gum, then counts them into a carton. Ace does that converting in Dongguan. The empty unit is about USD $0.04–$0.06, MOQ applicable.
I keep flower out of this sentence. Fill is another factory.
Why Is YouTube the First Result?
I searched “how are pre roll cones made.” The first organic result is a YouTube process video. Google’s next text page is Roll Your Own Papers: how to start a profitable pre-roll cone factory, using India as the example—bobbins, guillotine, 3D-printed rolling tool, hand rollers, overnight dry.
That article is a starter-kit pitch ($30 bobbin talk, INR day rates). It is useful for the step list. It is not Ace Rolling, and it is not a filled-joint line.
How are empty pre-roll cones made in a factory that already exists? Same skeleton: bobbin → cut → tip → wrap → dry → pack. Different plant, different quote.
| Étape | Ce qui se passe | What it is not |
|---|---|---|
| Bobbin | Jumbo paper unwind | Flower grind |
| Cut | Trapezoid / size | “King” with no mm |
| Conseil | Paper (or spec’d glass/wood) | A cigarette filter unless asked |
| Form + gum | Wrap, seal, dry | A filled pre-roll |
| EMBALLAGE | Bulk, jar, or box | A dispensary tube of flower |
What Does Ace Actually Convert?
Ace Rolling (Guangdong Ace Rolling New Material Technology Co., Ltd., Dongguan) converts Hengfeng-backed base paper under ISO 9001:2015. FSC is an option, not a default. Gum is food-grade arabic gum—a material note, not a health claim.
Common empty lengths: 84 mm, 98 mm, 109 mm, plus custom. Paper routes include white, unbleached, hemp, flax, bamboo, wood pulp, color, and print.
I’ve watched briefs that attach a Knockbox video and ask Ace to “make the pre-roll.” That video is fill. This page is paper.
How Is This Different From Making a Booklet?
A booklet is cut, gummed, interleaved, and boxed as flat leaves. It skips the mandrel and the tip. That is why booklet converting is cheaper and why Ace’s booklet band sits about USD $0.07–$0.30 per booklet, MOQ applicable.
How are empty pre-roll cones made in a factory that also makes booklets? On a second line. Do not expect one machine setting to jump from 32 leaves to a 109 mm cone.
What Should You Not Copy From a “Start a Factory” Post?
Do not copy wage math, headcount, or “45,000 cones per bobbin” as Ace facts. Those numbers are that author’s India example. Ace does not publish capacity slogans, and we will not invent them.
Do not treat IndiaMart machine ads as Ace equipment. Do not treat a filled pre-roll masterclass as cone converting.
Ask Ace for a sample in your millimeters instead of building a cottage line from a blog.
What Goes on the RFQ After You Understand the Steps?
I’ll quote empties, booklets, tips, packs, and jumbo rolls if you convert yourself. Ace does not fill tobacco or cannabis. MOQ from about 2,000+, moving with print, tip, and pack.
In my experience the “how is it made” call gets short when the buyer wants a carton, not a plant.

FAQ
How are empty pre-roll cones made in a factory?
Bobbin, cut, tip, wrap, dry, pack. How are empty pre-roll cones made in a factory at Ace? That converting happens in Dongguan on Hengfeng-backed paper. The empty unit is about USD $0.04–$0.06 with MOQ. Flower is never in the room.
Is the YouTube “pre-roll” video the same process?
Usually not. How are empty pre-roll cones made in a factory if the video shows people filling joints? That is a licensed fill line. Ace’s process stops at empty paper. Watch for grinders and trays—those are the giveaway.
Can I start my own cone plant from a blog?
You can try. How are empty pre-roll cones made in a factory versus a cottage setup in that India guide? Same step names, different risk. Ace already runs the converting. I would buy empties first and only then decide you need your own mandrels.
Do booklets use the same machines?
No. How are empty pre-roll cones made in a factory that also prints booklets? They run on a forming line with tips already inserted. Booklets stay flat and skip the mandrel entirely. Quote the two converting jobs as two SKUs and two price bands.
What sizes can that process make?
Ace commonly quotes 84 mm, 98 mm, and 109 mm, plus custom. How are empty pre-roll cones made in a factory if you only write “king”? The cut and the tray still need millimeters. Changing length later is often a tooling change, not a setting.
