<p>A multilayer gasket assembly and a method of making same in a verified correct sequence. Each layer (100, 200, 300) defines sensing formations which sensing formations when stacked over an array of sensors (420, A, B, C) sequentially in a superposed array verify and signify that the layers (100, 200, 300) have been correctly stacked to enable a subsequent operation such as one which secures the layers together.</p> |
