The decorative layer is cut from a fabric and the repeat patter picked up by a camera. It is then positioned on the backing and located under the press tool in the correct position, optionally together with a top wear layer, as guided by computer control. The sheet is then laminated under heat and pressure, removed from the press and checked by a comparison camera array with a computer. - The data is used for statistical control process control. The decorative layer can contain markings to indicate the pattern repeat and facilitate comparisons. The materials are humidity and temperature controlled before use to improve stability. The decorative layer can be stretched during impregnation to compensate for shrinkage during lamination. |
