Abstract

Sur les surfaces d'objets plats superposés (2), une charge électrostatique est produite en guidant lesdits objets (2) à travers un champ électrique équipotentiel sensiblement perpendiculaire à leurs surfaces principales. En raison de cette charge, il se produit entres les surfaces des objets, des forces d'attraction électriques qui accroissent l'adhérence mutuelle. Cet effet de charge électrostatique des surfaces des objets plats superposés est réduit ou annulé pour au moins l'une des deux surfaces participant à un point de séparation prédéterminé en traitant préalablement cette surface par un agent antistatique (3). De cette façon, il ne peut se former aucune concentration de charge sur cette surface, ou bien cette concentration peut très rapidement s'équilibrer, de sorte qu'il ne se produit au point de séparation aucun accroissement d'adhérence, ou bien un tel accroissement est beaucoup plus faible qu'entre les surfaces ne participant pas à un point de séparation.. Au point de séparation, les objets peuvent donc être déplacés mutuellement par une force plus faible. Le procédé convient en particulier pour l'ouverture appropriée d'articles imprimés multifaces.
