PROBLEM TO BE SOLVED: To provide a film bonding device capable of improving the product quality and producing a film at a high speed by preventing troubles generated when a solution film is bonded to the cast surface. SOLUTION: A film bonding device for bonding a solution film 3 extruded from a slit gap of a mouth piece against the surface of a moving cast has negative pressure areas 4, 5 each having an independent suction port upstream of the mouth piece in a direction in which the cast moves from a point wherein the solution film 3 is bonded to the cast surface and independent pressure reducing means, respectively, wherein at least one 4 of the negative pressure areas has a contact portion with the solution film 3 and the other negative pressure area 5 does not have a contact portion with the solution film 3. |
