Inner wrappers for packets of cigarettes are fashioned from a continuous strip of metal foil paper directed along a feed path internally of a cigarette packer, advancing through an embossing unit by which the metallic surface is textured, then through a rotary cutter such as will divide the material into leaves of specified length. The embossing unit is equipped with an assembly comprising a pair of rollers, also with a stabilizing mechanism that utilizes an aspirating roller to induce a controlled plastic deformation in the strip, canceling out the random deformations induced by the embossing action, and, with each revolution of the cutter, simultaneously advancing a portion of the embossed strip equivalent to the length of one leaf.
