1. A process for making a continuous tape of at least one metallic material from malleable metallic materials, the process comprising:
passing a continuous tape (1), having an initial width and having a thickness between 6.35 and 25 microns, of said at least one metallic material between a rigid cylinder (3) and a presser (2) made of elastically compressible material, kept adherent to said rigid cylinder and at the same time subjecting said continuous tape, in at least a portion of its passage between said rigid cylinder and said presser to a speed reduction of its surface in contact with said presser (21) with respect to the speed of its surface in contact with said rigid cylinder (3) the surfaces of the outgoing belt tape being always parallel to each other, wherein after said passage, the tape is extendible in the longitudinal direction between 5% and 20% and wherein a final width of the tape corresponds to the initial width.
