Abstract of the Disclosure The known type of sheet separating device in a packaging machine including a magazine for accommodating a plurality of flat sheets, a sheet separating device for separating only one sheet positioned at the lowermost level in the magazine from the other sheets including rockable seam hooks at one end edge of the magazine, rock- able side hooks on the both sides of the magazine and rockable suction arms adapted to suck the sheet at the lowermost level, a vacuum cup arm provided with vacuum adhesion means and driven by a crank mechanism so as to pull down the only one sheet separated by the sheet sepa- rating device and thereafter to be held still for a pre- determined period, and fixed guides adapted to be engaged with the sheet that is being pulled down for folding the sheet into a U-shape, is improved. The improvements reside in that in order to constitute means for reliably separating sheets positioned at the lowermost level in the magazine one by one, there are provided two stages of main and auxiliary side hooks which can be rocked in the direction for supporting the sheets and in the direction for releasing the same as operated inversely to the seam hooks, on the both left and right sides of the magazine so that the side hooks can be rocked in correlation with the suction arms, each of the respective side hooks has its supporting position for the sheets made variable, and the side hooks are adjustably disposed so that the interval between the side hooks on the left and right sides of the magazine can be varied with the main and auxiliary side hooks on each side held integrally.
