ABSTRACT:
In a process for dressing a substantially flat substrate having on at least one side a rough surface fibers protruding therefrom, there is first heated a support member, the upper side of which consists of silicone rubber having anti-adhesive properties and comprises small recesses for transmitting a pattern to said dressing, whereupon a first aqueous dispersion of synthetic plastics material is applied onto the upper side of this support member for forming a first layer of the dressing. Subsequently, this support member is heated from the bottom side located opposite the upper side of the support member at least till solidification of the first layer. Subsequently a second aqueous dispersion of synthetic plastics material is applied onto the solidified first layer or onto the rough surface of the substrate, said second dispersion forming a second layer of the dressing when having become solidified. In the following, the substrate is placed with its rough surface onto the solidified first layer, the applied second aqueous dispersion of synthetic plastics material still being in a wet stage. Subsequently, the support member is heated from its bottom side and a pressure is applied onto the upper side of the substrate during a time interval of at least 10 seconds, whereby the second aqueous dispersion of synthetic plastics material becomes solified. Subsequently, the substrate provided with the dressing is removed from the support member.
