Abstract (en)
[origin: US6569817B1] A composition containing an anti-static agent and a lubricant for treatment of a surface of a flat article (2) so as to define point of separation of a plurality of at least partly superimposed flat articles. Due to the lubricant, the friction coefficient between the treated surface and a surface of an adjacent article and, therefore, the static friction between the two articles is reduced. Due to the anti-static agent, static charging of the treated article and, therefore, adhesion between articles obtainable through static charging is reduced. In a plurality of superimposed, flat articles statically charged in a d.c. voltage field, the named two effects produce a displacement at the location of a treated surface, when a displacement force (11) with a component parallel to the principal surfaces of the articles is applied to the plurality of articles.
