What Is Changeover Time on a Folder Gluer?
Technical explanation of folder-gluer changeover time for carton buyers: what it includes, what drives it, how to measure it, and how to write changeover targets into machinery RFQs.
Quick answer
Changeover time on a folder gluer is the elapsed time from the last good blank of one job to the first sustained good blanks of the next. It usually includes belt moves, glue settings, feed adjustments, and quality checks—not only “how fast the machine can run.”
Why buyers should measure it
Plants with many SKUs lose more capacity to make-ready than to top mechanical speed. A high-speed claim with slow changeovers underperforms on short-run cartons.
What drives changeover
Blank size jumps, lock-bottom vs straight-line, coated vs uncoated stock, glue pattern changes, and operator skill. Crash-lock or multi-corner jobs often take longer than simple side seams.
How to specify it
Define start/stop points, which tooling changes are included, target minutes for named job pairs, and acceptable first-piece waste. Ask for a timed demo on your blanks at FAT.
Validate with real work
Do not accept a changeover number measured only on similar stock sizes. Trial the hardest adjacent SKUs in your mix.
