Anyway, you don't need to form your garlic bread into a ring shape (which would have to be done by hand, and therefore is expensive) to have "endless" garlic bread. You could extrude kneaded dough under pressure through a nozzle onto a metal mesh conveyor belt; then pass it under infra-red lamps to bake it, so you end up with just one continuous very long baguette with just one stump-end at the beginning and another when the dough in the dough hopper runs out. In the meantime, your bread just keeps on growing at a fixed rate; it can be sprayed on the cut end with liquid garlic butter, and then sliced every couple of centimetres.
