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.

Roll change apparatus

A first valve member has an axis and a first seat surface with a tapered contour facing axially downstream. A second valve member has a second seat surface with a tapered contour facing axially upstream. The second valve member has a closed position in which the second seat surface abuts the first seat surface, and has an open position in which the second seat surface is spaced axially downstream from the first seat surface. The second valve member further has a terminal end portion configured as a nose cone. The nose cone may be located entirely downstream of the second seat surface, and may have a cavity with a drain opening.
