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).

An apparatus for handling and setting up large slit-boxes of the type in which the slit-box is formed by a generally tubular slit-box blank having sides, two of which sides have opposed bottom inner flaps connected thereto and two other sides of which have opposed outer bottom flaps connected thereto, comprising; a magazine for receiving a pile of generally flat slit-box blanks, a catcher means displacable between a first position above the magazine and a second position to the side thereof for setting up the slit-box by successively engaging the uppermost slit-box blank in the magazine and moving the same to a setting up position, said catcher means including a catcher carriage which is displaceable between a position above the magazine and setting up position, said catcher carriage including a first set of catcher devices intended to engage one of the sides of the slit-box blank which faces upwardly and also engage the bottom flap connected to the first said side, which bottom flap is an outer bottom flap, further catcher devices positioned to engage another side of the slit-box blank adjacent to the first said side, which second side also faces upwardly when the slit-box blank is positioned in the magazine, means for moving the catcher carriage between said two positions, means for actuating the catcher devices and means for controlling operation of the catcher devices so that the second catcher devices associated with the second side of the slit-box container disengage that side before the first set of catcher devices disengage the first said side, means for folding in the two inner bottom flaps into the space between the two opposed outer bottom flaps and means for folding in the outer bottom flaps over the folded in inner bottom flaps.
