  • the middle area 10a of the carrier web due to the larger clear width L2 of the nip 23b with respect to L1 no deformation. are also in the area 20, 30 of the roller 2, 3 no surface profiles are formed.
  • the Rollers can now also be used with other profiles Embossing patterns of Figures 7 to 10 to be provided with the foils to provide corresponding stretchable embossing patterns.
  • edge strips 12 to the carrier web and simultaneous to facilitate plastic deformation by embossing the edge strips 12 furthermore the roller 2 with which the foils forming the edge strips 12 12a and the carrier web 10 before passing through the nip 23 4 first come into contact, heatable and points to it Purpose connections 24 for a heating medium. It is thus possible to use the roller 2 in particular for the connection and plastic deformation Plastic films 12a with the longitudinal edges 10b of the carrier web 10 heat the required temperature.

  • the heatable edge strips 12 and / or carrier web 10 can be brought about be dimensioned such that an applied according to arrows P in Figure 4 Adhesives, for example a hot melt adhesive, before the thermal connection is activated, or the heating is so great that the edge strips from out with the carrier web as it passes through the nip connect. This also applies when connecting with edge strips from a metal foil.
