Patent

CA 2295416

A system and a method for coating two sides of a laminate material is disclosed in which one side of the laminate material is coated with one substance and the second side is coated with a similar or different substance. Reverse roll coating may be used to coat the two surfaces of the sheet of laminate material. The method described is particularly suited for applying a substance providing characteristics desirable in the manufacturing process to one side of the laminate material and applying a substance providing characteristics desirable in the end product to the other side of the laminate material. For example, a release agent may be applied on one side of a kraft paper sheet and phenolic resin on the other side, thereby eliminating the need to use release sheets in the manufacture of laminates. The kraft sheet thus coated may be used in a decorative layer or a backing layer to form a laminate panel that may be applied on an exterior wall, an interior wall, siding, a roof top, a facade boarding, a counter top, a table top or a work top.
