Abstract
A method of fastening a liquid-impervious sheet (7) to a wound pad (5) that is comprised of an elastic, hydrophilic material and that will expand in all directions when absorbing fluid. The pad (5) is stretched to a given extent both longitudinally and transversally in the plane of the pad and a flat liquid-impervious sheet (7) is then applied to the stretched pad and the load acting on the pad is removed. An absorbent dressing that includes an inventive wound pad (13) is also disclosed.
