We are working on a suction conveyor, becuase it can transport fragile things in stable state.
Here is a video to test transport of a piece of paper.
This air nozzle pushes air on this paper.
When it is not sucked, paper is blown.
Then it is sucked. It is not shaken and stays on the belts.
Suction transport is fine for thin and light material.
