What is more difficult to understand, is the distributor. The best that I can tell, mats are inserted at a single point, into the escapments at the top of the machine. Then, somehow the mats find their way to their respective slot in the magazine.
It is difficult to tell whether the machine was successful. I might have succeeded, but a world war completely devastated the German economy. Language barriers and time prevent our knowing much of anything about it. Perhaps our German friends can research this.
