  • Apparatus for impregnating and coating paper
    Patent number: 6231670
    Abstract: A paper web impregnated with a liquid resin and following impregnation is coated with an abrasive particle containing coating mass or composition and then dried before a liquid resin is applied which does not contain the abrasive particles. The web is then finally dried and the resulting paper is particularly suitable as a cover sheet in the hot pressing of laminates since it minimizes wear of the laminate press.
