The present invention pertains to a method wherein a concavoconvex cutting line is applied repetitively in a periodical way in the longitudinal direction of a continuous first web to form first and second partial webs; said first partial web is offset with respect to said second partial web in the longitudinal direction by a prescribed interval so that the concave edges and the convex edges of the first and second partial webs are positioned opposite to and aligned with each other, whereafter a continuous second web is used to connect the outside edges opposite to the said aligned concave and convex edge portions of the first and second partial webs, and as the second web is bonded with the outside edges of the partial webs a composite web is formed, following which the first and second partial webs of the composite web are spread apart.
