The continuous manufacture of pressed panels such as chipboard or fibreboard from loose material is effected on apparatus having a taut, endless belt passing sequentially around a portion of the periphery of each of a feed roll, a squeeze drum and a counter pressure roll, the loose material being loaded onto the belt and squeezed between the belt and the squeeze drum, the feed roll and counter pressure roll acting on an opposite face of the belt to that bearing the material, at least the feed roll and squeeze roll being heated, a line perpendicular to a line joining the axes of the squeeze drum and the feed roll forming an angle of between 0 DEG 40 DEG with the horizontal and the distance between the feed roll and the counter pressure roll being such that regression of the compressed loose material at the outlet from the counter pressure roll is avoided. |
