<p>A heating system (1) for hot coupling or laminating at least two films or thin sheets, e.g. of plastic material, that are dragged by at least one moving support (2; 2b), said heating system (1) comprising at least a heater group (10) comprising at least: -- a burner (14) fed with a combustive agent and a fuel, and - an airtight chamber (11) delimited by a radiating internal face (12) and a non-radiating external face (13); wherein said burner (14) comprises at least one combustion head (15) generating an aeriform flow at temperature of combustion fumes that is directed towards said airtight chamber (11) and heats its radiating internal face (12) and wherein said radiating internal face (12) faces said at least one moving support (2; 2b) so that a heating volume (3) is defined between said radiating internal face (12) and said at least one calender cylinder (2; 2b) through which said at least two PVC or plastic films pass and are heated up to their hot coupling temperature by the heat released by said radiating internal face (12).</p> |
