Two cartoning lines, 14 years old, running three shifts. Holmgaard's lines were reliable enough to keep, but not reliable enough to plan around. Unplanned stops ate one shift in seven.
The drive trains were the weak point. Six gearboxes from three suppliers, no spare parts on the shelf, and no data on why they failed. "We were replacing parts after they broke, never before," says plant manager Jens Holmgaard.

Before touching hardware, our application engineers logged a week of machine states on Line 2. The filler wasn't the problem. The carton erector was: it stopped 23 times a shift, mostly for 2–4 minutes, and every stop starved the stations downstream.
