Abstract: A roll support apparatus suitable for use in a roll coating machine is described. The roll support apparatus includes a roll support frame for rotatably supporting a roll coating head roll associated with the roll support frame, the roll support frame adapted for pivoting movement relative to a roll support frame mounting base. Furthermore, a roll carriage suitable for use in a roll coating machine is described. The roll carriage includes a roll support frame for rotatably supporting a respective roll and further includes a roll support frame mounting means for movably mounting the roll support frame so that it moves between a coating position and an idle position, wherein the roll support frame mounting means in use is mounted substantially above the respective roll to inhibit contamination of the roll support frame mounting means.
