Abstract (en)

The present invention concerns an embossing cylindrical roller 1 comprising a plurality of micro-protuberances distributed in correspondence of its outer cylindrical surface and destined in use to emboss a paper tape 2. In accordance with the present invention the roller 1 has a circumference which length C is a multiple of the cut off length L of said tape. This means that the overall length C of the circumference is equal to the product between an integer number N and the length L of cut off, C = N x L . The integer number is equal or higher to 2. In this manner the circumference can be subdivided in a number of sectors Cn that coincides with said multiple number N and in which each sector comprises said pluralities of micro-protuberances distributed on its surface so as to define on each one of said sectors a specific design Dn. According to this configuration of the roller, in correspondence of each complete rotation of the roller this cyclically imprints the tape according to the sequence corresponding to the designs Dn provided on it, each of which is destined to be printed inside an area of the tape delimited by said cut off length L.
