Used Leather Finishing Machines: A Buyer's Checklist
Finishing is where used tannery equipment gets expensive to get wrong.
A drum can be inspected in an hour and repaired almost anywhere; a roller coater with a worn engraved cylinder, or a spray line whose extraction no longer meets ATEX, is a machine you cannot legally or economically run until you have spent more than you saved. This is the machine-by-machine checklist.
Why is finishing machinery riskier to buy used than wet-end machinery?
Wet-end equipment — drums, fleshing, splitting, shaving — is mechanically brutal but conceptually simple. Finishing equipment is not. Three reasons it carries more hidden cost:
- The consumable is the expensive part. On a roller coater the engraved cylinder, on an embossing press the plate, on a spray line the guns and recirculation pumps. These wear items are frequently the majority of the machine's real value and are the first thing a seller quietly omits.
- Compliance travels with the installation, not the machine. A spray booth needs extraction, solvent handling and, in the EU, an ATEX assessment of the zone. Buying the machine does not buy you a compliant installation.
- Electronics age faster than steel. A 1998 hydraulic press with a mechanical control is fixable forever. A 2008 machine with an obsolete PLC and a discontinued HMI can be dead for want of a €400 board that no longer exists.
If you are earlier in the process, the general framework is in how to value used tannery machinery and the seller's side in selling with a guarantee.
What should you check, machine by machine?
| Machine | What it does | What actually fails | Inspect before paying |
|---|---|---|---|
| Roller coater | Applies finish by engraved cylinder | Cylinder engraving worn flat; doctor blade scored; feed belt stretched | Run a hide. Check coat weight uniformity edge to edge; ask the engraving depth vs original spec |
| Spray line / carousel | Sprays finish on a moving conveyor | Gun wear, clogged recirculation, extraction below spec, corroded booth panels | Spray water and look at the pattern from every gun; ask for the extraction airflow measurement |
| Embossing / plating press | Heat + pressure, grain or gloss | Platen flatness, heating zone dead spots, hydraulic seal creep, plate inventory | Thermal-map the platen; press a test panel and check corner-to-corner impression |
| Milling drum (dry drum) | Softens and breaks grain | Bearing wear, worn pegs, unbalanced rotation | Listen to it running empty; check the drum door seal |
| Staking machine | Mechanical softening | Worn pins, belt tracking, uneven pressure across width | Stake a hide and check across the full width, not the centre |
| Toggle dryer | Stretches and dries | Frame corrosion, clip inventory, heating uniformity | Count and price the toggles separately; they are a real cost |
| Measuring machine | Measures area for invoicing | Calibration drift, sensor bar faults | Measure three known hides; a 2 % drift on your invoicing is a permanent tax |
| Buffing machine | Sands the grain | Extraction, drum bearings, paper feed | Dust extraction condition is the tell for how the plant was run |
A practical note on the measuring machine: it is the cheapest machine on that list and the only one that touches every invoice you issue. Buying a poorly calibrated one is the rare case where used equipment loses money every single day it runs.
What are realistic price bands for used finishing equipment?
Treat these as orientation, not quotation. Condition, brand, working width and — above all — whether the wear parts are included move the number far more than age.
| Machine | Typical used range | Biggest swing factor |
|---|---|---|
| Roller coater, 1.8 m | €18,000 – €55,000 | Cylinder inventory and engraving condition |
| Spray line, 6–8 guns with dryer tunnel | €25,000 – €90,000 | Tunnel length, extraction, control generation |
| Embossing press, 1.400 t hydraulic | €20,000 – €70,000 | Plate inventory included or not |
| Milling drum, 3 m | €8,000 – €25,000 | Wood condition, motor and gearbox |
| Staking machine, 3.000 mm | €12,000 – €40,000 | Pin wear and control generation |
| Toggle dryer, 30 frames | €15,000 – €45,000 | Frame count and clip inventory |
| Measuring machine | €4,000 – €15,000 | Calibration certificate and sensor generation |
The rule that saves the most money: price the machine and the wear parts separately, in writing. A roller coater at €30,000 with two worn cylinders and one at €38,000 with six good ones are not close — the second is cheaper. Sellers know this; most buyers ask about hours instead.

What questions separate a real seller from a broker?
Ask these five. The answers, and how fast they arrive, tell you who you are dealing with.
- “Can I see it running, with material?” Not powered up — running, with a hide. A refusal is the answer.
- “What is the PLC and HMI model, and are spares still available?” A seller who has to look it up has never maintained it.
- “Which wear parts are included, itemised?” Cylinders, plates, guns, toggles, pins, blades. In writing.
- “Why is it being sold?” Capacity change, article change and closure are all fine and verifiable. Vagueness is not.
- “Who dismantles, and who signs the electrical and safety declaration on reinstallation?” In the EU, a machine placed back into service after substantial modification can trigger a new conformity assessment. This clause moves real money.
Add the boring logistics question that people forget: weight, footprint and whether it fits through your door. A 3 m staking machine that needs a wall removed is a different purchase.
Frequently asked questions
Is it worth buying finishing machinery older than 20 years?
Often yes for mechanically simple machines — milling drums, toggle dryers, hydraulic presses with mechanical controls. Rarely for anything whose value sits in electronics or in a coating head. The dividing line is not age, it is whether the expensive part is steel or software.
How much should I budget for reinstallation?
As a planning figure, 15–30 % of the purchase price for dismantling, transport, reinstallation, electrical connection and commissioning — higher for spray lines because of extraction and ducting. Machines bought cheap far from home routinely close that gap.
Do I need new CE marking on a used machine?
A used machine sold within the EU and put back into service unchanged generally keeps its original status. If it is substantially modified, or imported from outside the EU, the obligations change. Get this answered by your own safety consultant before the deposit, not after.
What is the single most common mistake?
Buying on hours and age instead of on wear parts and controls. Hours are unverifiable on most tannery equipment; the state of the cylinders, plates and guns is not.
Buying or selling finishing equipment? Post it on the open board. The TL San Martín Business Board is a free, open B2B board for the leather and footwear industry. Surplus & machinery is where plants list what they are releasing — a line being replaced, a press that no longer matches the article mix, spare cylinders and plates — and where buyers post what they are hunting.
