Abstract

An embossing device comprises a first embossing roller and a second embossing roller forming a passage for a web of wrapping material to be embossed, which has a main line of extension and a direction of feed; the first embossing roller comprises on its outer surface toothings to make an imprint on the web; a first toothing having a first impression to imprint on said web a first segment of a reference for identifying a section of the web and a second toothing to imprint a decorative pattern on the web; the second toothing comprises a zone without teeth for defining on the web a second, unembossed segment of the reference; the first toothing and the zone without teeth are offset from each other along a directrix of the first roller.

Claims18

Dependent claims

A method for identification of a section of a continuous web having a main line of extension and movable in a direction of feed according to a predetermined path, said method comprising:

a step of definition on said web of a reference associated with said section,
a step of reading said reference to identify said section using the contrast between said reference and said web, said method being characterized in that said step of definition of a reference comprises a step of embossing said web using an embossing device,
said reference comprising at least a first embossed segment and a second unembossed segment, said first segment having a contrast compared with said web which is different to the contrast of said second segment compared with said web, said first and second segments being positioned on said web along respective strips parallel with said main line of extension,
said method comprising a step of reading the reference segment out of said first and second segments which has greatest reading contrast, said section being identified based on the segment having the greatest reading contrast.

1 more element

An embossing device comprising a first embossing roller and a second embossing roller which form a passage for a web of wrapping material to be embossed, said web having a main line of extension and a direction of feed, said first embossing roller and said second embossing roller being positioned relative to each other for embossing said web as it goes through the passage, at least said first embossing roller comprising on its outer surface means to imprint a reference on said web for identifying a section of said web, said device being characterized in that

said imprinting means comprise a first toothing having a first impression to imprint on said web a first segment of said reference according to a first pattern;
at least a second toothing having a second impression to imprint a decorative pattern on said web, said second toothing comprising a zone without teeth for defining on said web a second, unembossed segment of said reference, said first toothing lying on a first band of directrices of said first roller and said zone lying on a second band of directrices of said first roller.
