PROBLEM TO BE SOLVED: To provide an apparatus and a method for producing a sheet-fused body, in each of which uniform pressurizing force can be imparted to a belt-like sheet laminate as an object to be fused.SOLUTION: The apparatus for producing the sheet-fused body, which body has the sealed edge fused in such a state that the edges of two or more pieces of sheets are overlapped, includes: an irradiation head; a supporting member 21 for supporting one surface of the belt-like sheet laminate 10; and a pressing member 26 for pressurizing the belt-like sheet laminate 10 toward the supporting member from the other surface side thereof. The supporting member 21 has a slit-shaped opening 27 which is made longer in the width direction of the sheet laminate 10. The pressing member 26 has circulating caterpillars 24a, 24b and a plurality of pressurizing members 25 attached to each of the circulating caterpillars. The sheet laminate 10 to be kept in a pressurized state by the pressing member 26 is irradiated with a laser beam 30, which is converged from the side of the supporting member 21, along the opening 27, the sheet laminate thus irradiated is divided and the sheet laminate is fused in a state that the divided edges thereof are overlapped. |
