ABSTRACT:
A method and a device for production of a web with good breathing properties, for example having a nonwoven web based on plastic filaments and/or plastic fibers and a plastic film, applied on one side of the nonwoven web and containing at least one mineral filler. For the production of the good breathing properties, the web is stretched in the longitudinal direction of the same, in two successive steps, and an embossing is carried out, at least in certain sectors of the surface, between the two steps which effect the stretching in the longitudinal direction.
