IIRC. the Documation readers (and perhaps others) read the card from the end
rather than from the side. They were typically lower speed, 200-1000 CPM,
maybe less. They picked the card with a vacuum I think, rather than pushing
it with a knife edge (if that's the right term). Thus they could easily
handle cards of any length.
