Abstract
A method of producing an intermittent elastic web of material. According to the invention, an elongated elastic element (1) is laid-out in a pre-stretched state and in a longitudinal extending wave form and is fastened to a longitudinally extending web (2) such that the web transversely touches or extends beyond the outermost part of wave crests (3) and wave troughs (4) of the wave-shaped elastic element (1), whereafter a longitudinal cut (C) is made in the web so that at least outer parts of wave crests and wave troughs are located on mutually opposite sides of the cut.
