  • Patent number: 7077924
    Abstract: A method for producing tapes in pairs for the manufacture of closing tapes for baby diapers. The tapes are formed mirror-symmetrically and secured on the baby diapers in pairs. The method comprises the following steps: a web of material is separated in four strips, whereby two strips are processed as plane support tapes. The two other strips are guided via reversing stations over the support tapes and folded to form release tapes that each comprise a short leg and a long leg. Closing tapes that comprise male or female closing elements for a mechanical self-closure, are laminated to the support tapes in the direction of transport of these support tapes. The release tapes are applied to the support tapes in the direction of transport, whereby the short leg is glued to the support tape, and the long leg at least partly covers the closing tape that has been applied to the support tape. There is also a device for producing the tapes using the method described above.

  • Patent number: 6620492
    Abstract: A laminate is provided made of two film materials with different tear resistance values, particularly made of polyester and polyethylene. The part of the laminate made from a film material with a high tear resistance is structured in multiple layers and has at least two layers made from this high tear resistance material connected with one another by an adhesive layer with a low shear resistance. This structure results in a laminate having improved tear resistance.
