Способ по п.4, отличающийся тем, что с первого слоя материала, используя предварительное натяжение нанесенных эластичных слоев, до соединения со вторым наружным слоем снимают натяжение и укорачивают первый слой таким образом, что материал полосы, получающийся таким образом в комбинации со второй наружной лентой материала, на стороне ленты, образованной первым наружным слоем, характеризуется повышенной складчатостью.
12. Способ по одному из пп.4-11, отличающийся тем, что на обращенную к суперабсорбенту сторону второго наружного слоя наносят дополнительный контактный клей для плоскостной фиксации суперабсорбента в сухом состоянии.
13. Эластичный, гибкий и абсорбирующий или резорбирующий материал в виде ленты, изготовленной по пп.4-12.
