Patent ID: 8741083

Claim:
A method for producing an elastically stretchable laminate comprising at least three layers, comprising: a) Producing a first laminate comprising a first non-elastic fibrous nonwoven web and an elastic film; b) activating the first laminate by incremental stretching in at least one activation direction and partially tearing the first nonwoven web to render the first laminate elastically stretchable; c) stretching the activated first laminate to 10 to 200% in the activation direction; and d) laminating the stretched first laminate to a second non-elastic nonwoven web, such that the elastic film is between the first and the second nonwoven webs, wherein in the elastically stretchable laminate, the second non-elastic has a width greater than the width of the first laminate and extends past the first laminate on one or both longitudinal sides thereof, and wherein the activation direction is a longitudinal direction.
