A box or carton sealer is disclosed having a frame with a conveyor for moving boxes therethrough. First and second longitudinal, laterally spaced-apart, independent gravity operated centering bars move inwardly and outwardly to center the boxes in the sealer. The centering force produced by the centering bars is proportional to the distance the box is off center in the sealer. A shiftable weight assists the respective centering bars to move laterally as required. A floating head has an inclined entry ramp for riding up over the box and lifting the floating head to a desired height as the box passes thereunder. The floating head has a sealing device for attaching the box flaps at whatever height the flaps happen to be at under the floating head.
