Device for embossing and laminating web material consisting of two or more plies

Embossing and laminating device comprising a pair of embossing cylinders with each cylinder having tips arranged thereon, said pair of embossing cylinders being positioned such that an axis of each cylinder is parallel to each other and said pair of embossing cylinders are adjacent to each other to form a nip therebetween, and each cylinder rotates at a same peripheral speed and in opposite directions;

• a pair of pressure rollers, each of which works in conjunction with one of said pair of embossing cylinders;
• a glue applicator associated with a first cylinder of said pair of embossing cylinders;
• and a laminating roller positioned downstream of the nip and working in conjunction with said first cylinder which is associated with said glue applicator;
• wherein
• said first cylinder associated with said laminating roller has a diameter greater than that of a second cylinder of said pair of embossing cylinders;
• and said pair of embossing cylinders can have a positioning of their tips changed back and forth from a coinciding configuration so that lamination occurs within said nip to a configuration where the tips of the first cylinder fit between the tips of the second cylinder so that lamination occurs between said laminating roller and said first cylinder by changing a synchronization of said cylinders.
