摘要

An embossing device comprises a first embossing roller and a second embossing roller forming a passage for a strip of wrapping material to be embossed; the first embossing roller comprises on its surface a tooth set to imprint a pattern and an imprinting system to imprint a reference on the strip to identify a section of the strip: the imprinting system comprises an area without teeth in the tooth set, extending along a sheaf of directrices of the first roller for forming on the strip a non-embossed band in the pattern; the imprinting system comprises a second tooth set lying on the sheaf of directrices to imprint an embossed mark on the strip in the non-embossed band.
