Abstract
The invention relates to a method and a device for achieving adhesion between layers of tissue paper, according to which a surface structure corresponding to that of sandpaper is pressed into the product along the side of at least one roller when the individual layers are joined in a roll nip. This results in good adhesion between layers with only minor optical impairment of the product surface and without the use of glue or such like.
