<P>PROBLEM TO BE SOLVED: To provide a method of imparting elasticity to a non-woven material/elastomer laminate. <P>SOLUTION: The method of imparting elasticity to the laminate containing at least one elastic film having a width and at least one non-woven material layer fixed to the film with particularly a bonding material, particularly an adhesive agent placed between them, has a step of developing the laminate into a web shape so as to pass the laminate between two pairs of engagement mechanisms. The method of engaging teeth of two pairs of engagement mechanisms with each other in the direction vertical to the plane of the laminate so as to extend the laminate in the widthwise direction, also has a step of giving the web a tension in a vertically sectional direction or in a vertical direction during the development between the engagement mechanisms by providing particularly a tensioner roll particularly in the downstream of two pairs of the engagement mechanisms. <P>COPYRIGHT: (C)2008,JPO&INPIT |
