My idea is:
We must apply electromagnetic for this system for hold masking plate in position as we need. And demagnetize when no use it.
1. Idea we need order electromagnetic setting use spray unit and masking plate it magnetic belt or rubber. For easy to control.
2. Order special electromagnetic belt by spec as we need to maker, trial and test.
For detail of this idea please see data as below link
