Germany-based Schober Technologies has introduced a cutting pressure regulator. This electronically-controlled device allows for active pressure control which maximizes tool life and guarantees higher productivity.
With the new cutting pressure regulator, a diecutting head mounted onto a stepper unit is driven into position against an anvil cylinder by a servo motor and generates specific, pre-calculated cutting pressure. The cutting pressure between the cutting and anvil cylinder is constantly regulated so that the desired pressure is guaranteed during the non-stop operation.
Feedback signals from the servo motor are constantly monitored to ensure that the cutting force between the diecutting and anvil cylinder remains constant. This means that the cutting quality will not be affected by fluctuation in the speed of the web. Due to the precisely controlled cutting pressure, tool wear is reduced to a minimum thus increasing the life of the tooling. Additional advantages include: no scrap generated from bringing the machine down and back up, increased productivity, reproducible setting data and fast change-over.
