PFIS — Pharma Folding Inspection System
The module order is Hugger Module, then the patented Curing Module, then the Inspection Control Unit (ICU). The inspection uses a bottom belt only, with two AI cameras and no top belt. The cameras check for unglued leaflets, skewed folds, and overlap or underlap at the top and bottom of the booklet. Sold whole or as separate modules.

Process
Hugger Module → Curing Module → Inspection Control Unit
Hugger Module
Squares the leaflet after the knife folder applies glue, while the glue is still wet. The Hugger can run independently of the inspection system.
Curing Module (patented)
Holds outserts under pressure for several minutes so the pressure-sensitive fold glue fully sets before anything is inspected.
Inspection Control Unit (ICU)
Bottom belt only, with two AI cameras and no top belt. The cameras check every piece for unglued leaflets, a skewed fold, and overlap or underlap at the top and bottom of the folded booklet. The fold stays visible, so a failed glue bond shows itself.

The key difference
If the glue didn't hold, the outsert tells on itself.
Because only the bottom belt holds the piece, the fold remains visible to the cameras. An outsert whose glue did not hold physically springs open and sits taller on the belt — and that physical signal is what triggers automatic rejection.
Competing systems transport the piece between a top and bottom belt. That clamping blocks camera access to the fold, so those systems can only confirm that glue was injected — never whether it actually holds the fold shut.
Side by side
MJR vs. a typical top-and-bottom-belt system
| MJR Literature Inspection | Typical top-and-bottom-belt system | |
|---|---|---|
| Transport | Bottom belt only — fold stays exposed | Top and bottom belts clamp the piece |
| Camera access to the fold | Unobstructed, two AI cameras | Blocked by the top belt |
| What is actually verified | Whether the fold is holding shut | Only that glue was injected |
| Reject mechanism | A failed outsert springs open, sits taller on the belt, and is automatically rejected | No physical signal available — a failed bond can pass |
| Glue set before inspection | Patented curing module holds pieces under pressure for several minutes first | Inspection without a dedicated curing stage |
| Barcode print & verify | Integrated single-pen inkjet barcode print, with a third camera that verifies the printed barcode quality | Typically a separate add-on |
Barcode reading & print verification
Add the MJR Z-Camera System.
PFIS’s third camera verifies the quality of the barcode printed by its single-pen inkjet. For more, add the MJR Z-Camera System, the highest-capability of our three Pharma Retrofit Tiers. In this application it reads the barcode and detects print by counting pixels, with dual live views on a PC-based touchscreen monitor, and it can be configured for much more.
