The embossed or printed web material article comprises at least two plies (V 1, V 2 ) of tissue paper joined together by gluing and forming at least one multi-ply sheet. The sheet has a principal pattern (D), embossed or printed, in a substantially intermediate position with respect to the surface of the article, and secondary embossed or printed patterns (U, V) of smaller dimensions arranged along the edge lines of the article and interrupted by said edge lines. FIG. 3 schematically shows an axonometric view of the embossing roller ( 21 ). The cylindrical surface of which is indicated with 21 S. Defined on the surface of the roller are annular i.e. circumferential areas or bands ( 21 C), along which protuberances are arranged to define an embossing pattern, which will be referred to hereunder as circumferential secondary embossing pattern. A longitudinal band ( 21 L) is also represented on the cylindrical surface of the embossing roller. In actual fact, several longitude bands are provided along the circular extension of the roller. As in case of the circumferential bands, protuberances defining an embossing pattern, which will be referred to hereinafter a longitude secondary embossing pattern, are also provided along the longitudinal bands. |
