In several of their later projects, they actually
distributed
"Port-a-punch" cards, and had people slap a stamp onto them and MAIL THEM!
SOME had to be completely repunched, and some had to be duplicated one at
a time on an 029. ?BUT, MOST of them were readable! ?I heard that what
they did was use a simple hydraulic press on the decks, and then IBM
enlarged (opened to its maximum?) the gate of the card reader.
IBM had duplicating punches that could handle really mangled cards.
For example, the punch cards used by tube dealers back in the 1960s
(used for reordering) were typically folded in three inside a sleeve
of tubes.
