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.
