  • Patent number: 5477901
    Abstract: For the manufacture of high pressure laminates, the pressed laminate (4) consisting of a stack of artificial resin impregnated paper sheets is fed into a single daylight hot press. The pressed laminate is held and guided along both longitudinal edges (6) by transfer clamps (7), which are connected to an endless rotating chain (8) and are conveyed on guide tracks (15). The transfer clamps (7) remain closed during the transfer into the single daylight hot press, during the pressing process and during a following cooling process in a cold press.

  • Patent number: 5229217
    Abstract: The invention concerns the production of a decorative high-pressure laminate with a surface layer (3) on the surface of which an adhesive primer layer (4) of polyvinyl butyral is applied. The adhesive primer layer (4) enables a lacquer coating to be applied subsequently, so that a lacquer layer optimally suited to the particular application for which the laminate is eventually used can be chosen. The adhesive primer layer (4) can be applied by impregnating a web of paper with melamine resin, dusting the impregnated web with polyvinyl butyral powder while the resin is still wet and then drying. Another way of producing the coat is to apply polyvinyl butyral in alcoholic solution to a web of paper which has been impregnated with melamine resin and dried, and subsequently drying.
