An improvement in an apparatus for setting up and closing the bottom of cartons or so called slit-boxes which are supplied as plainly collapsed carton tubes having sides and bottom and top flaps which are integral with the sides. The apparatus comprises a support (1) which carries a magazine (2) for carton blanks, a feeder unit (3) and a bottom flap closing means (4). The feeding unit (3) includes a suction catcher (11) adapted to catch and open a container blank and to move the said blank along a handling path while closing at least bottom thereof. The feeding unit carries an expelling means (27) having an expellor arm (28) which is moveable between a position inside the handling path and a position outside the handling path and which is mounted at a predetermined distance in front of the feeder unit (3) as considered in the feeding direction. The expellor arm (28) is actuated by a hydraulic or pneumatic cylinder (31) to move to a position inside the handling path when the suction catcher (11) starts to move along the handling path after having pulled a carton blank (6) out of the magazine (2) and to move the expellor arm (28) out of the handling path after the suction catcher with the expellor arm (28) and the set up carton has reached a predetermined end position and just before the suction catcher (11) starts to return to its initial position in contact with the foremost carton blank (6) of the magazine. |
