Abstract
In a process for continuously making disposable wearing articles, a first web which will be finally cut into a series of sheet members that are contiguous to one another in a transverse direction, and that define an outer surface of the article, is continuously fed in a first machine direction. A second web having a Ω-shaped cross-section forming individual adhesive taper strips is fed in a second machine direction orthogonal to the first machine direction. The second web is periodically cut in a second cross direction orthogonal to the second machine direction to obtain composites. After the composite is fed to and attached to the first web, the first web is cut together with the composite so as to bisect the length of the composite.
