You should use a steam iron.
You mean on all 30,000 of them? :)
Hi Sellam
Maybe one of those industrial steam irons used at the
commercial laundries. I was thinking that you were dealing
with them one at a time. For bulk, you might look into how
the banks iron bills. They have some method that means they
have some kind of machine to handle the problem. These
machine must be making it to scrap dealers.
Now that brings back a flash from the past. I can't remember if the context
was bank checks or punched cards, (probably the latter), but way back in the
past I remember seeing a machine that would slowly feed such a document
between a pair of rollers. The rollers had a pattern in them not unlike a
cutter that would be used to produce a crosshatched knurling pattern on a
tool handle, but the pattern was not as deep. They used substantial pressure
and would straighten the subject document right smartly. Fingers too, no
doubt.
