Abstract
Here is disclosed method for attaching elastic band to sanitary articles such as disposable diapers. The elastic band is cut into predetermined lengths which are then intermittently attached by adhesive to a web forming said articles. Said elastic band is severed on a surface of a rotary suction drum so that the respective lengths thus severed and isolated may be intermittently attached to said web. Said elastic band may comprise a plurality of relatively narrow or fine rubber strands. Particularly in such a case, said elastic band is attached to a support tape wider than said elastic band and having high flexibility before cutting so that these rubber strands may be reliably held on the surface of said suction drum.
