The Bank Note Machine

When a blank piece of paper is put between the rollers,  it comes out the other side printed like a $1 note. A black cloth "blind" goes twice round top roller and is then run twice round lower roller in opposite direction.
The $1 note is rolled onto bottom roller before you start the trick.
$1 note comes from under blind on lower roller. Blank slip goes under blind on top roller. Enlarged end view of rollers, showing the “blind” that goes round each roller.
