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.
