A pair of longitudinal, laterally spaced-apart gravity operated centering bars are linked together and move inwardly and outwardly in unison to centre the boxes in the sealer. A first floating head has an inclined entry ramp for riding up over the box folding the box forward end flap inwardly. This floating head also has a pivoting arm for folding inwardly the rear end flap of the box, and diverging side bars for folding inwardly the side flaps of the box. A second floating head has an entry ramp for riding up on top of the inwardly folded flaps of the box. The second head has a tape dispenser for applying tape to the flaps at whatever height they happen to be at to tape the box shut.
