Abstract:
A lamination process for orienting and conforming a film or a sheet material to a substrate surface having a surface feature in a manner effective to conform the film or sheet material to reflect said surface feature, comprising the steps of:interposing an adhesive between the film or the sheet material and said substrate surface and opposing the film or the sheet material and the substrate surface the one to the other under conditions suitable for adhesion;providing at least two pressurized manifolds, each said manifold providing a plurality of flow streams of a pressurized liquid delivered from their respective manifold, said flow streams being oriented to provide a clear but minimally overlapped resulting flow stream from each manifold;directing the resulting flow streams of a pressurized liquid onto said film or said sheet material to coincide at a contact nip line, said resulting flow streams comprising a force effective to conform the film or the sheet material to the surface feature of the substrate surface; and,maintaining the resulting flow streams for a time sufficient and under conditions suitable for the adhesive to affix the film or the sheet material to the substrate.
