摘要:
A method of forming an elastic laminate including at least one elastic film and least two nonwoven webs laminated to each of the sides of the elastic film. The elastic film is fed in a machine direction towards a bonding station. The elastic film is stretched in the machine direction at a stretch ratio from 1.5 to 8 times of its original length, thereby forming a stretched film and the stretched film and said at least two nonwoven webs are laminated in the bonding station. The elastic film is stretched in at least two stretching steps before laminating it with the at least two nonwoven webs, wherein between 5 and 25% of the total stretching occurs in the last stretching step before lamination in the bonding station.
