For laminating a web (3) with a stretched web (2), the stretching operation for the web (2) is immediately followed by feeding in the unstretched web (3) and laminating it on to a certain extent within the stretching apparatus (4) by utilising the stretching heat - preferably after independent preheating - so that a heat-laminated multilayered web (13) is formed, in which both webs (2 and 3) may consist of the same or the same type of material, which is particularly favourable for reprocessing. The advantages of such a composite web comprising a stretched web and an unstretched web are thus achieved without adhesive being required for forming the bond. …IMAGE…
