ABSTRACT:
This method is directed to the continuous making of a flexible compound structure having a controlled perviousness and consisting of an assembly of a textile web, a thermoplastic film and a foam web in a machine where these elements are heated and welded together between a pair of calender cylinders; means are provided for measuring continuously the perviousness of the resultant compound structure; according to the desired degree of perviousness, the welding parameters are adjusted so as to change the linear speed of the structure, and/or the pressure exerted thereon by the calender cylinders and/or the temperature of the heating means; this invention is applicable more particularly in the textile industry for manufacturing products such as wall coverings and the like.
