DIY Paper Tape Punch - Mechanism diagram?

I've had a paper tape reader for a while but never had a punch to make new
tapes, and the ones i've found are not only very large but also very
expensive. So I'm toying with the idea of making an open-source punch, but
I can't find any detailed diagrams of how the mechanism works.
I'm assuming (without any data to back it up) that there is a cam, an array
of spring-levered pins, and horizontal spacers controlled by solenoids that
bridge the gap between the cam and each punch pin when called for.
Does anyone have insight into how reliable/fast paper tape punches work?
