The mechanics has no adjustment or spring tension on
the pinch roller
positions. ... all the spring is in the rubber of the rollers.
But how much squish?
...
I'm hoping someone might have some knowledge of how much punch card
reader pinch rollers should press against capstans. Does 0.2mm squish
seem right
To produce a given force on the card, the dimensional amount of squish needed
would depend on the rigidity of the material, no? A stiff material would
need/want less than something soft, I would think.
