ABSTRACT:
Method comprising a thermal treatment step proper during which said sheets are in contact with a part of their surface (that is they are, for example, coiled or in tight packets) and a step of preliminary treatment of these surfaces by means of an aqueous solution or a water-alcohol solution into which an organic product of the silane type has been introduced.
This treatment makes it possible to prevent the sticking of the sheets; it is particularly effective and it does not require any preliminary activation of the surface.
