Abstract
The invention relates to a method of manufacturing an elastic laminate (1) in which a web (10) of elastic material is continuously fed out, stretched and attached in stretched condition to a supporting material in the shape of a moving support web (2). The support web (2) has a greater extension across the direction of movement of the web (2) than the web of elastic material (10), causing sections (18) of the supporting web (2) to protrude latitudinally on each side of the web (10) of elastic material. The laminate is divided into two longitudinal web-parts (20, 21) along a curved dividing line (15), causing the web (10) of elastic material to be cut off in a plurality of pieces (26) and tongues (23) of material formed from the divided web (10) of elastic material and flaps (25) laminated thereto from the supporting web (2) protrude out from, and are connected to, strip-formed edge-sections (18) of the supporting web (2) on both sides of the dividing line (15). The laminate can be used for forming elastic elements on absorbing articles such as diapers, incontinence protectors or sanitary napkins.
