ABSTRACT:
The installation produces a material, as a prefabricated flexible foil, for finishing and decorating buildings, of the type in which a cover with several layers of granules, spread upon a supporting net, has the granules bound to each other and to the yarns of the supporting net by invisible fine pellicles of a thermoplastic synthetic resin binder. The installation comprises: means for priming the supporting net of natural textile fibers; a conveyor belt, for supporting and displacing the supporting net on which suitable means spread all at once the granule layer and press it slightly, then another following means sprays it, from above, with the binder dissolved in a solvent or dispersed in water; a heating tunnel which receives, on a conveyor belt of wire net the supporting net with the granule layer and the sprayed and retained liquid; infrared heaters located below the wire belt in the tunnel which evaporate the liquid, while the released binder forms into fine pellicles; a smooth roller which detaches from the conveyor belt the resulting material foil, which, when leaving the tunnel, passes between two smooth rolls, for slight compaction of the foil and cooling means which cool down the foil.
