Embodiment Construction
[0019] In the method shown in the figure, an elastic film 1 is stretched transversely to the web direction in a preactivation station 11 and cut into strips 2 after elastic relaxation. The strips 2 are guided via a deflector 3 and are laminated side by side between two nonwoven material webs 4 and 5 as parallel strips. The material webs 4 and 5 are guided without pretensioning above and below the strip 2 and are adhesively or thermally bonded to the strip 2 . The view clearly shows that the elastic strips 2 are laminated between the covering layers at a distance from one another and that the nonwoven covering layers 4 and 5 are directly bonded together in the interstices between the elastic strips 2 . Elastic regions 6 and inelastic regions 7 are thus formed in the laminate 8 . The laminate is supplied to an activation unit 9 in which the laminate 8 is stretched transversely to the web direction in the region 6 rendered elastic by the laminated strip 2 . After elastic relaxa...
