Thin materials with fragile edges cannot be edge guided, they need to be actively aligned using an edge detector that feeds back position measurements to the PLC.

Steering rollers can be used or the entire roll can be shifted with a servo slide to keep the edge precision aligned to the die set

Prismatic batteries use thin coated electrode materials that need to be actively aligned

Tension control is very important. We have some “Innovative” techniques for light tension control for membrane and fragile materials

This example punched membrane disks from a sheet of membrane material. The system adjusted the punch pattern to maximize the material use.

Zero-Clearance punch and dies, active edge guiding and precision tension were needed for this application
