Abstract
Method for imparting elasticity to a laminate comprising at least one elastic film having a width and at least one ply of non-woven material secured to the film, particularly through interposition of a bonding material, particularly glue, which comprises the following steps in which: the laminate is unrolled in the form of a web in order to pass it between two sets of toothing, of which the teeth engage in each other in a direction perpendicular to the plane of the laminate in order to thus stretch the laminate in the direction of its width, characterised in that: a tension is imparted to the web in the longitudinal direction or machine direction during its unrolling between the toothing, particularly by providing a tensioner roll, particularly downstream of the sets of toothing.
