<p>In the manufacture of chip-board and boards of similar materials in a double band press, where the board is to have a width (38) less than the nominal working width (34), the moulding bands (1, 2) are held on the support structure (17, 18) in a position enduring the transfer of heat to the marginal zone (35) extending from beyond the edge of the material which forms the boards to within a short distance of the edge (31) of the moulding zone. At this point marginal material (36) consisting of binder-free particles is incorporated by pressing, or a compressible band is set into motion therewith.</p> |
