Abstract:
This invention relates to a method for crimping a web of material for the tobacco industry, including the following steps:
feeding a web of material for the tobacco industry along a feed path;
crimping the web between two crimping rollers operatively coupled to make a plurality of longitudinal easy folding lines on the web;
measuring a value of a thickness of the web before the step of crimping;
The step of crimping the web is adjusted as a function of the thickness value measured during the step of measuring.
