Patent ID: 8691051

Claim:
A method for manufacturing a security paper material comprising the steps of forming a paper sheet from a wet cellulose fibre pulp and providing the paper sheet with electronic chips, the electronic chips being introduced into the paper sheet being formed during transformation of the wet cellulose fibre pulp into paper, the electronic chips being deposited directly onto the wet cellulose fibre pulp and at least partially embedded in the wet cellulose fibre pulp, comprising the steps of: feeding the wet cellulose fibre pulp to a Fourdrinier type continuous papermaking machine; depositing the wet cellulose fibre pulp on a flat forming table that defines a horizontal plane; forming the paper sheet by gradually subtracting water from the wet cellulose fibre pulp, the electronic chips being deposited in the wet cellulose fibre pulp directly onto the flat forming table on an upper side of the paper sheet being formed and on a flat and horizontal surface of the paper sheet on the flat forming table and being fed by a dispensing device arranged over the flat forming table and being dropped in free fall by gravity onto the wet cellulose fibre pulp, wherein the electronic chips are deposited on the wet cellulose fibre pulp by the dispensing device at predetermined intervals both in a direction of advancement of the paper sheet being formed and in a transversal direction; coupling an auxiliary paper sheet to the upper side of the paper sheet being formed, wherein the coupling is performed after depositing the chips in the wet cellulose fibre pulp and while both the paper sheet being formed and the auxiliary paper sheet are still wet and lie on the flat forming table; and wet rolling the paper sheet being formed and the auxiliary paper sheet, while they both are still wet and disposed within the horizontal plane, by means of a rolling assembly having two or more counterpoised pairs of rolls, wherein the paper sheet is not press rolled before being coupled with the auxiliary sheet.
