Boxes each having a plurality of relatively short side panels having upper edges three of which are free edges and one of which is connected to a cover panel itself having free edges and at least one flap projecting from one of the free edges are closed by first inserting the boxes one after the other into respective pockets formed between crosswise partitions on an endless conveyor belt spanned over a plurality of rollers. Each cover is folded onto the respective box by engagement with the partitions of the respective pocket on insertion of the respective box into the respective pocket. Then adhesive is applied to the flaps while the boxes are in the pockets and the adhesive-coated flaps are pressed against the boxes while the boxes are in the pockets.
