Patent DE-19826800-A1 (DE)
Title: Special paper for securities and banknotes etc.
Inventor: PUTTKAMMER FRANK
IPC: G07D7/00
Filed: 1998-06-16
Abstract: In the production of a special paper, with electrically conductive characteristic matter as proof of origin, the conductive material is of pigments and/or transparent polymers. They are added to the machine vat by a dosing system (17,19) for a homogenous mix with the paper material and/or spread homogeneously or in part over the paper web surface. The added conductive material is a dispersion and/or suspension applied to the paper web surface by a droplet tube (17) for a partial distribution in continuous or interrupted lines, or by a controlled dosing unit (17,19) with continuous or intermittent working. The conductive additives can be added to the machine vat, to be stirred into a homogenous mixture with the paper material during pulp preparation, to be fed to the fourdrinier section of the paper making machine as a homogenous pulp for the special paper. With conductive pigments, they are moved in a continuous circuit through the supply container (26) by pumps (20), for delivery to the paper web by a dosing unit (19). The conductive material can be transferred to the paper web by watermark embossing rollers wholly or partially at the watermark image die. The additives have an electrical conductivity or other physical values and/or chemical characteristics for authentication by a multiple scanning action. Independent claims are also included for: (1) A scanning system to test the authenticity of the paper. The sensor to monitor the electrical conductivity has a number of scanning channels activated by an optical, magnetic and/or electromechanical sensors. Preferred Features: The capacitative scanning sensor extends over the whole width of the paper sheet. The sensor is structured to reduce the scatter coupling and give a narrow difference between the conductivities of adjacent test zones which can be measured.  The sensor channels are controlled so that, on the first scan, the channels with even numbers are used, and in each alternate scan, channels with odd numbers are in force, with a scanning frequency of pref. 200 kHz. The gap between the sensor electrodes and the receiver electrodes can be altered according to the test structures and the test plane. The electrically conductive additives have a particular reaction in the optical spectrum range, as a reference value for the electrical conductivity in a double test action. A roller or sliding rail retainer holds the paper sheet flat while being carried through the test apparatus. The sensor electrodes can be on two planes to the paper sheet, with a functional electrode side over the paper and the other functional electrode side under the paper sheet under scrutiny. (2) A paper making machine with a number of scanner sensors over the whole width of the paper web to monitor the maintenance of production parameters. Preferred Features: A control circuit is after the sensor array, to determine the feed of additives to the pulp or the web surface.
