    I've never met a rolling mill that doesn't have adjustment knobs.
    Most have two knobs at the top and to either side of the handle that
    adjusts the rollers to thin or thick. 

    Get a feeler gauge from a hardware store or auto parts supplier to
    help you determine the correct adjustment, as it will save lots of
    trial and error. Insert the thickest gauge in between the two rollers
    until it just catches on one side of the rollers or the other. On the
    side that's high, adjust the top knob in a counterclockwise motion
    until the roller also touches the feeler gauge on that side. Then
    tighten down the rollers to catch a feeler about half way in the set
    of feeler gauges, and adjust the knobs again. Keep doing these two
    steps until you're down to the thinnest feeler. 

    Keep the feeler gauge. In the future, you may find a need to roll
    wire to a wedge shape or to introduce a curve to sheet, and so you
    would open up one side of the rollers higher. It's also useful for
    doing certain types of fold forming when in this position. But of
    course you'll want to be able to put it back to the level position
    for most rolling.
