GEM F470/520/670 is an automatic carton sealer with manual dimensioning and flap closer. It folds automatically the four upper flaps and seals with auto-adhesive tape the top and bottom of batches of uniform size, American-type boxes. The upper taping unit has a patented system which, by regulating a spring, enables the subsequent weight on the box to be preset and therefore any differences in height of the boxes to be absorbed. The boxes are fed by lateral conveyor belts, driven by a single motor thus optimizing even sliding of the boxes and ensuring perfect alignment of the upper and lower flaps which in turn guarantees perfect sealing. Adjustment by means of handwheels is easy and fast, enabling use by non-specialist operatives.
