Abstract
A rolling machine has pairs of rolls in a horizontal line of roll pair locations, with each pair including upper and lower rolls opposed across a vertical gap. A sliding frame is mounted on the rolling machine for movement alongside the rolling machine in a direction parallel to the line of roll pair locations. A lifting frame is mounted on the sliding frame for movement vertically relative to the sliding frame beside each of the roll pair locations. Other parts include a roll cassette and a load tray. The load tray is configured to carry the roll cassette, and is mounted on the lifting frame for movement relative to the lifting frame transversely into the vertical gap between the rolls at each roll pair location.
