Corner rounders give print projects a polished finish with smooth, rounded corners. As print becomes more personalized, specialty finishing equipment is essential. Basic straight cutting is still common, but for a distinctive look, corner rounding stands out.
Corner-rounding cutters handle many paper stocks. For simple jobs, a manual desktop model can be ideal, while larger electric models support higher volumes. This article focuses on larger machines, which are often misused. Below are maintenance tips to keep your corner rounder performing its best.
The size and design of the corner-rounding die limit how many sheets you can cut at once. Overloading the die is a common mistake. Some heavy-duty electric models can handle large lifts (e.g., up to ~700 sheets of 20 lb paper), but always follow your machine’s specifications.
All corner rounders collect trim waste. If the tray isn’t cleared, debris can back up and damage blades and dies. Empty the tray after each run to protect the tooling and maintain cut quality.
Paper dies are for paper—don’t use them on metal or other hard substrates. For metal signs or tougher materials, use the proper machine and die set designed for that application. Misuse can chip or prematurely wear the die.
Dull blades slow production and degrade the finish. Professional sharpening requires removing blades from the machine, but sharp tooling ensures faster throughput and cleaner cuts.
Replacement can cost about the same as sharpening—without the downtime of sending blades out. Update Ltd stocks a range of replacement blades for popular round corner cutters.
