  • Patent number: 7060158
    Abstract: A process for the manufacture of a decorative boards, which boards includes a decorative layer, wherein a decor sheet is placed as a surface layer on a base layer and bonded thereto by pressing under elevated temperature and pressure. The decor sheet is cut to a predetermined format from a web, the cut being arranged on a fixed position related to possible repetition frequency of a decor pattern of the web. The decor sheet is then accurately placed on a base layer with a predetermined format. The decor sheet is spot welded to the base layer. A number of such base layers with attached decor sheets are then, one after the other, fed in between the belts of a continuous laminate press, optionally together with an uppermost wear layer. The base layers, the decor sheets and possibly the optional wear layer is then laminated together under heat and pressure in the laminate press.
