The means for gradually opening the stoppers 23a, 23b provided on the front surface of the corrugated board sheet 1 and supplying the sheets to the corrugated cardboard magazine 25 side sequentially from the front side while receiving the resistance of the stoppers 23a, 23b is adopted.

However, in such a means, when the stoppers 23a and 23b are opened and the corrugated board sheet 1 is fed into the corrugated board case magazine 25 from the leading side of the row, an inconstant number of sheets 1 naturally fall and the magazine 25. The sheets are stacked inside, but when the sheet supply to the corrugated cardboard magazine 25 is stopped, the stoppers 23a and 23b are forcibly forced.
As the sheet is closed, problems such as damage and tear of the sheet occur. Further, since the magazine 25 is formed to be slightly wide, the dropped sheets 1 can be stacked in the magazine 25 in a non-uniform state in the front-rear direction. As a result, after this, when the sheet 1 is sucked by a suction cup or the like and supplied to the corrugated cardboard case, the suction position may shift and a trouble may occur. Further, when replenishing the corrugated board sheet 1 on the pedestal 24, it is necessary to fully consider the timing at which the stoppers 23a and 23b are opened and the sheet 1 is dropped, and if this timing is deviated, there is a problem such as occurrence of trouble. .
