from The Century Dictionary.

  • noun One who or that which adjusts the opening between the rolls in the roll-train of a rolling-mill, so that thicker or thinner material shall result from the rolling process. This adjustment of the bearings of the rolls is effected by screws which have a graduated scale and pointer by which the opening is indicated. In early forms of mill this adjustment and screwing was done by a workman; in modem mills it is done by power, either through belt-driven shafts or by an electric motor under the control of the man.
