Beschreibung
Zusammenfassung:	An elastic laminate is provided including outer facing layers of a fabric and, located between the outer facing layers, a series of individual, spaced apart strips of elastic film extending continuously along the direction of elasticity. The film strips are formed by a controlled tearing of a continuous film while the film is biaxially stretched and bonded to the fabric facings. The fabric facings have gathers formed therein that allow the elastic laminate to stretch at least to the extent that the gathers can be pulled flat. L'invention concerne un stratifié élastique comprenant des couches de parementure externes d'un tissu et, située entre les couches de parementure externes, une série de bandes individuelles et espacées les unes des autres de film élastique s'étendant de manière continue le long de la direction d'élasticité. Les bandes de film sont formées par déchirure contrôlée d'un film continu tandis que le film est étiré de manière biaxiale et collé aux parementures de tissu. Les parementures de tissu comportent des fronces qui permettent au stratifié élastique de s'étirer au moins dans la mesure où les fronces peuvent être étirées à plat.
