The upstream section (2) has means (8) (e.g. steam chests) for heating the board (4) during its passage through the upstream section (2). The downstream section (3) has first and second endless belts (12, 13) which do not extend into the heating section (2). The belts (12, 13) have facing runs between which the board (4) may be held and the downstream section (3) has means (12a, 13a) (e.g. air plenums) for pressing the facing runs of the first and second belts (12, 13) towards each other to hold the board therebetween.
