Claims

[Scope of Claim for Utility Model Registration] A bag-like sheet closing device for closing a bag-like sheet inserted into an open case and folded back in a U-shape from the top opening of the case to the outside of the case, a plurality of vacuum suction means for sucking the outer surface of the sheet folded portion at opposing positions; a sheet lifting means for lifting the sheet folded portion attracted by the vacuum suction means; and a vacuum in the central portion of the plurality of vacuum suction means. a vacuum selection means for keeping only the suction means in a suction state; a tensioning means for stretching the vacuum-selected sheet suction section outward to the left and right at a height substantially corresponding to the upper end of the open case; a venting means that presses the top surface of the sheet corresponding to the case opening while maintaining the tension of the sheet to bleed out the air inside the seat; one side overlapping means for overlapping the sheet extension part on the upper surface of the sheet in the case opening, and the other side overlapping means for overlapping the sheet tensioning part stretched outwardly on the other side by the above tensioning means over the upper surface of the one side overlapping part. A closure device for a bag-like sheet, comprising means.
