<p>The invention relates to a tray for the production of hardboards for doors, comprising cavities for panelling or glazing. According to the invention, the trays (1, 66, 102) are moved continuously and filled with wood particle board and binder in the form of a blanket (43, 85) that is supplied by formers. The base (16,32,103) of the tray is provided with a series of holes (10, 11; 73, 74; 104, 105) which correspond to the cavities in the doors that are intended to be panelled or glazed. The contour of the holes (10, 11; 73, 74; 104, 105) and at least the longitudinal walls of the tray (1, 66, 102) are equipped with a retractable casing (12-30; 84-86; 93-94-86; 110-115) which can absorb the difference in the thickness of the blanket (43, 85) before and after pressing. The front and rear ends of the trays (1, 66, 102) are equipped with means (50, 75, 77, 118, 121) that enable the trays (1, 66, 102) to be connected and to move through the press.</p> |
