PURPOSE: A two sided sheet treating system is provided to coat one side of the laminate material with one substance and the second side with a similar or different substance, thereby eliminating the need to use release sheets in the manufacture of laminates. CONSTITUTION: A system for coating two sides of a laminate material is provided 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. A method for coating two sides of a laminate material 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. 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.
