A professionally refurbished Heidelberg Stitchmaster ST 450 with guaranteed spare parts and worldwide service — backed by the engineers who originally built it at Heidelberg.
The ST 450 is Heidelberg's final and most advanced Stitchmaster generation. Many features and components of today's Müller Martini Primera are based on Stitchmaster engineering.
With Allaoui, you can now configure a fully refurbished Heidelberg Stitchmaster line — a modern, globally serviced saddle stitching solution at a fraction of the cost of buying new. Expect six-figure savings compared to a new machine, with no compromise on performance or support.

Five reasons the ST 450 — Heidelberg's final and most advanced Stitchmaster generation — earns our recommendation for shops that need real production performance without the price of new.
01
Matching the top speed class of current-generation saddle stitchers. Servo-driven feeders deliver ~20% higher net performance than the previous Stitchmaster generation — the rated speed translates into actual throughput on the production floor.
02
Every module — feeders, stitcher, trimmer, stacker — is driven by its own servo motor, synchronized via electronic shaft. Format adjustment is automatic across the entire machine. Mobile feeders can be positioned anywhere on the gathering chain.
03
04
05
Individual servo drives for every module, electronically synchronized. Dynamic offset, on-the-fly corrections to feeder timing, stitch position, and wire length without stopping, staggered stitch at button press — a generation ahead of conventional mechanical drives.
This isn't "cleaned up and resold." Every ST 450 goes through a comprehensive, multi-stage process by the ex-Heidelberg engineers who originally built these machines.
Our technicians handle careful dismantling at origin to prevent damage.
Every aggregate cleaned — feeders, stitching unit, trimmer, stacker, electronics.
Every aggregate systematically inspected for wear, damage, and condition.
All parts showing any sign of wear are replaced — not just the obvious ones.
All functions and safety devices verified and documented.
All incorrect settings reset to original Heidelberg factory specifications.
Thorough paper test run — production-quality output verified before release.
Leaves the workshop ready for production — not "ready to be fixed on-site."
"Our engineers didn't just learn these machines — they built them."
Over 400 Stitchmasters are still running in 50+ countries worldwide.
With their network of engineers Allaoui secures worldwide availability of service and spare parts.
Comprehensive inventory through the ex-Heidelberg network.
Installation, commissioning, operator training.
Diagnostics and troubleshooting from Leipzig.
Ongoing preventive maintenance programs.
Europe, Americas, Asia, Middle East, Africa.
Critical wear and replacement parts available through the ex-Heidelberg network — supplied to original specification, fairly priced.

The most significant difference between these machines isn't technical — it's financial.
| Machine | Typical market price | Notes |
|---|---|---|
| Primera C130/C140 (used) | €200,000 – 250,000 | Conventional, no Amrys |
| Primera E140 (used) | €265,000 – 330,000 | With Amrys automation |
| Primera MC (used) | €475,000 – 550,000 | Full servo, rare on the market |
| Stitchmaster ST 450 (refurbished) | €240,000 – 300,000 | Fully refurbished · 6-month warranty · parts & service included |
If you're operating an ST 100, ST 250, ST 300, ST 350, or ST 400, you already know the platform. The jump from an ST 400 to a 450 is bigger than most people realize.
| Area | Older Stitchmasters (e.g. ST 400) | ST 450 |
|---|---|---|
| Feeders | TAL/TAS generation — more stops, more product movement | DVU2/DHU2/CHU — servo-driven, ~20% higher net performance |
| Stitching heads | Hohner heads — higher wear, shorter lifespan | Heidelberg 45-N14 (built in-house) — less wear, longer life |
| Electronics | Mixed Lenze + B&R — heat issues, fault-prone | Unified B&R platform — fewer faults, improved cooling |
| Quality control | Camera only; thickness control can mark products | Camera + barcode per feeder; marking-free thickness control |
| Stacker | Rima stacker — issues with small formats and landscape | Heidelberg CHA — full format range, reliable 2-up production |
| Max feeders | 16 | 24 |
| Trimmer | Requires accessories for extreme formats | Full range without accessories, plus 3-up (TRIO) option |

A high-volume US bindery chose the ST 450 — here's why.
When Taylor Corporation needed a saddle stitcher for its high-volume bindery, it specified a fully custom-configured Heidelberg Stitchmaster ST 450 — four vertical and four horizontal feeders, three cover feeders, and barcode plus image-recognition cameras for inline quality inspection. Allaoui overhauled and fully tested the machine in Germany before shipment, and guaranteed spare-parts availability — the condition that sealed the deal and turned a single purchase into a long-term partnership.

Allaoui Graphic Machinery is a specialist in used and refurbished print finishing equipment, based in Aachen, Germany, serving customers worldwide. For the ST 450 program we partner with ex-Heidelberg postpress engineers who built these machines at the original Leipzig factory.
No — Heidelberg stopped production when they exited the postpress market in 2014. But over 400 machines are still running worldwide, and every ST 450 from Allaoui is fully refurbished by the ex-Heidelberg engineers who built them.
Yes — comprehensive inventory available through the Allaoui network. View the spare parts catalog →
Yes, it's possible — but it usually comes at extra cost. Stitchmaster-compatible stream feeders have to be specially ordered in the required size from a specialist manufacturer that produces stream feeders compatible with the Stitchmaster. If stream feeders are essential for your application, we would normally recommend going for a Primera instead.
On many specs — feeder count, barcode capability, mobile feeders, stitching heads — the ST 450 matches or exceeds the Primera, at a significantly lower price point. See the full comparison →
Yes — on-site installation, commissioning, and operator training by ex-Heidelberg engineers, available worldwide.
