<p>A method of producing strip comprising at least two material layers of different chemical composition bonded one to another, in which separate slurries of powders of different chemical compositions are formed in film-forming cellulose derivatives. Dried layers in strip form are produced from the slurries and these layers are fed, while under tension in interfacial contact, into the nip of a pair of compaction rolls to effect a mechanical bond between the layers. At least one of the strip layers may be subjected to a sintering operation prior to being fed into the nip of the compaction rolls.</p> |
