A method for modifying the physical and/or chemical characteristics of a web of paper material includes the steps of causing a web of paper material, having a dry content between 1% and 90%, to adhere to an endless conveyor belt of elastic material, subjecting the conveyor belt and the web to at least one localized dimensional variation, and introducing at least one additive between the fibers of the web while adhering to the belt before or during the localized dimensional variation. |
