Glue the new shutter curtain onto the drums (rubber side to the metal). Use a glue that can glue rubber and metal together. I used classic Pattex. Apply the glue to the drum and place the drum onto the curtain, otherwise the curtain will roll itself.
When dried, put the new curtains in place, starting with the spring tensioned drums (I found no need and no way to disassemble these).
