PURPOSE: A device for holding longitudinal parts of a folding paper box prevent damage or separation of a vertical supporter of a paper box when pressing the vertical support by controlling the pressing force according to the thickness of a paper board. CONSTITUTION: A device for holding longitudinal parts of a folding paper box comprises a guide plate(410), a first pressing plate(420), a second pressing plate(430), a first lifting unit(440), a second lifting unit(450), and a holder(460). The guide plate receives and guides a vertical supporter which is extended from the end of a vertical inner wall of a folding paper box. The first pressing plate is connected to one side of the guide plate with a guide ring and ascends and descends along the guide ring to press the vertical inner wall and the vertical supporter in the vertical direction within the guide plate. The second pressing plate is connected to the guide plate and a rotating block and rotated by the descending force of the first pressing plate to press the vertical support toward the holder. The first lifting unit is provided on the top of the guide plate and lifts the guide plate. The second lifting unit lifts the first pressing plate. The holder accommodates the vertical supporter which is pressed by the first and second pressing plates. |
