Abstract

Improvements introduced in the object of Main Patent No. 378,192 by: "A process for the continuous formation of a homogeneous layer" of polymer material on the surface of a multilayer material in the form of a flexible band, by applying the layer under pressure First mentioned on the surface to be coated of the multilayer material, applying heat and pressure at the same time, a procedure in which in a first stage a layer of heat-weldable material is applied to the surface of a synthetic material carrier sheet that has At a softening temperature higher than 130ºC, in a second step of the process the carrier sheet of the heat-sealable layer is applied under pressure and at the welding temperature of the heat-weldable layer, but lower than the softening temperature of the carrier sheet, on the surface of microporous structure, consisting of a polymer, of a multilayer material, in such a way that the ca heat-sealable polymer pa on the carrier sheet, and the microporous polymer layer of the multi-layer material, are turned towards each other, while in a third step of the process the carrier sheet is removed from the combination formed at a temperature below the welding temperature of the heat-sealable layer, characterized in that in the first stage of the process a heat-sealable layer of polyurethane is applied to the surface of the synthetic material carrier sheet, or, superimposed, at least two laminated layers of an elastic polymer heat-weldable, of which at least one consists of polyurethane, the application being made in such a way that the layer supported on the carrier sheet consists of polyurethane.
