A method and an apparatus for handling and setting up large slit-boxes of the type which is formed by a tubular slit-box blank (6) which is collapsed into a flat two layer blank and which comprises sides (7,8) with connected inner flaps (9) and outer flaps (10) respectively at at least one end of the slit-box. The slit-box is handled in a horizontal position by means of a catcher carriage (16) which is displaceable between a first position over a magazine for slit-box blanks (6) and second position for setting up the slit-box blanks. The carriage has a first set of catchers (17) to catch a first side (8) and its connected outer flaps (10) in the first layer of slit-box blanks and a second set of catchers (20) to catch the second side (7) in the upper layer of the slit-box blank. The said second side (7) is released so that the slit-box by its own weight moves to a more or less open position. The inner flap (9) of the released slit-box side (7) in then introduced into the space between the outer flaps (10). Finally the outer flaps (10) are folded in over the inner flaps (9). The folding in of the said first mentioned inner flap (9) is preferably by means of a crank arm (22) having a horizontal arm portion (24) which both provides a substantially complete straightening up of the container blank into parallelipedical tube form by folding in the inner flap (9) and a retaining of the two inner flaps (9) during a predetermined phase of the folding in of the outer flaps (10) over the inner flaps (9). The apparatus may comprise means for sealing the outer flaps (10) to the inner flaps (9). |
