Method and device for the manufacture of corrugated material, at least one first plane sheet ( 19; 20 ) and one second sheet ( 16 ) of plastic material arranged in wave shape being brought together for adhesion to each other and the wave-shaped sheet ( 16 ) running over core bars ( 17, 18 ). A portion of at least one sheet is heated at abutment against the core bars ( 17, 18 ) and the first sheet ( 19; 20 ) is brought to abutment against the second sheet ( 16 ) for welding the sheets ( 16; 19, 20 ) together. First members are arranged for feeding at least the first plane sheet and the second sheet of plastic material running over core bars ( 17, 18 ) and second members are arranged for bringing together and adhering the sheets. Heating members ( 28 ) are arranged for transferring heat to a portion of at least one sheet ( 16; 19, 20 ) abutting against the core bars and including plastic material. Furthermore, guide members ( 17, 18; 21; 22 ) are arranged for bringing together the first and the second sheet in an abutment portion and for welding in the portion heated by the heating members ( 28 ). |
