Abstract
An automated knife change adjustment on dual-gearbox paper cutting machines employs servo motors driving, with great gear reduction, turnbuckle nuts on a pair of pull arms. A graphic user interface automatically controls the knife adjustment on a replacement knife, the interface computer being connected to position sensors for the knife, to main motors driving gearboxes that cycle the knife down and up, to the servo motors and other sensors. The system avoids tedious manual steps typically in setting a replacement cutting knife to a correct cutting position.
