Abstract

The invention relates to improvements in manufacturing substrates and in particular to a method of manufacturing a fibrous substrate, such as paper, incorporating an electronic circuit. A method of making a fibrous substrate comprises the steps of depositing fibres on a support surface to form a fibrous mat and incorporating at least one electronic chip (11) during the fibre deposition process. The support surface comprises means for modifying the distribution of fibres as they are deposited on the support surface to provide at least one area (13, 14) of the fibrous mat having a grammage which is greater or less than that of the rest of the fibrous mat. The said area (13, 14) is positioned with respect to said chip such that the thickness of the substrate in a region of the chip is not greater than the thickness of the substrate in a region of the substrate immediately adjacent the chip.
