发明名称 METHOD OF PRODUCING A CORRUGATED BOARD AS WELL AS A CORRUGATED BOARD
摘要 In the case of a method of producing a corrugated board for protecting electrostatically endangered articles 10 against electrostatic discharges and electric fields, at least one corrugated layer 1 and at least one flat layer 2, 3 are glued together, a shield means 4, which contains carbon and/or graphite, being applied, prior to the glueing of said layers 2, 3, to the surface 40, 50, 60 of at least one layer which will be located in the interior of the corrugated board structure. This shield means 4 is applied as a layer, which comprises interconnected layer components 80 and intermediate interspaces 90 occupying a certain area, before the layers 1, 2, 3 are glued together in the area of said interspaces 90. The interspaces 90 are either completely free or covered by thinner layer components 90' occupying a certain area and constituting part of the shield means 4. In the corrugated board W, which is produced in accordance with this method, the layers 1, 2, 3 including the shield means 4 between them are glued together preferably in the area of the interspaces 90, if necessary through the thinner layer components 90'.
