This Screen Cutter was built for a company that makes Vent Blocks. They are used between trusses on residential construction. It cuts the screen that they use to cover the holes or slots in the blocks.
It uses only compressed air for power and runs in two modes. The first mode is continuous, were it cuts one piece after another until it runs out of screen. In the second mode it will cut a new screen as soon as the last one is removed from the machine.
