A novel method for manufacturing a layer of a laminated, disposable absorbent product, such as a fluid-permeable cover layer, an absorbent core layer or a fluid-impervious backing layer thereof, with a comparatively small amount of waste matter. The method comprises the steps of longitudinally cutting a continuous web of starting material according to a cyclic pattern constructed with line segments corresponding to the edge contour of the disposable absorbent product. The cutting operation divides the continuous web in two strips, each strip having a patterned longitudinal edge whose outline corresponds to the cyclic pattern. The strips are crossed and joined to one another in a parallel and in a phase relationship to form a compound web having longitudinal edges producing repeatedly the edge contour of the disposable absorbent product. The invention extends to integrating this method into an operation for manufacturing disposable absorbent products, and to a novel apparatus for carrying out the methods according to the invention and the resulting products.
