METHOD AND APPARATUS FOR PRODUCING BOARD AND A BOARD PRODUCT |
摘要 |
<p>A method is disclosed for producing a multilayer paperboard product, as well as an assembly suited for implementing the method and a paperboard manufactured according to the method, whereby the paperboard is made from at least two, advantageously three layers (4, 5, 6) bonded to each other by gluing, and the material of the middle layer (5) is subjected to mechanical working in a dry state (8) so as to deform the material prior to gluing through pressing thereon desired pattern that is raised from the surface of the material (5). The layers (4, 5, 6) are bonded to each other in a single step (7). The method is capable of providing a strong paperboard that uses less fiber than prior-art paperboards of equal thickness and strength.</p> |
