The method for the production of a material web from which elastically rotatable diaper closure elements are puncturable, comprises laminating foil stripes from an elastically extensible polymer in a first lamination station (9) between two material webs (10, 11) from nonwoven and adhering the web sections between elastic foil stripes, and guiding a laminate of a second lamination station (13) manufactured in the first lamination station, where non-elastic material stripes are laminated from the laminate. The non-elastic material stripes are subjected on web section of the laminate (12). The method for the production of a material web from which elastically rotatable diaper closure elements are puncturable, comprises laminating foil stripes from an elastically extensible polymer in a first lamination station (9) between two material webs (10, 11) from nonwoven and adhering the web sections between elastic foil stripes, and guiding a laminate of a second lamination station (13) manufactured in the first lamination station, where non-elastic material stripes are laminated from the laminate. The non-elastic material stripes are subjected on web section of the laminate (12) in which the layers of the non-woven are adhered. The web speed by which the laminate passes through the second lamination station is driven so that the web speed is less than the speed with which the material web is brought together from the non-woven and the elastic foil stripes in the first lamination station during the laminate formation. Stripes (6, 7) from the nonwoven or foil stripes for non-elastic polymer are laminated as reinforcement stripes on a first side of the laminate. Bands are laminated with connection elements on the second side of the laminate in the second lamination station. The non-elastic material stripes laminated external side of the laminate is wider than the web section between the elastic foil stripes. Hot-melt adhesive is used for the production of the laminate manufactured in the first lamination station and for the lamination of the non-elastic material stripes in the second lamination station. The web speed in the second lamination station and the web speed with which the material web from nonwoven and the elastic foil stripes in the first lamination station are brought together are adjusted so that the speed stands in determined constant ratio. The web speed in the second lamination station deviates to 0.1-1.0% of the speed with which the material web and the foil stripes are brought together in the first lamination station. |
