Balloons are sorted by dropping them into a hopper located above a suction device. A movable carrier is arranged between the hopper and the suction device such that balloons dropped into the trough and urged towards the suction device are gripped by means of the movable carrier. In an alternative arrangement, balloons are dropped onto a table, and a pair of gripper rods is moved so as to engage the necks of the dropped balloons, thereby to orient the gripped balloons in a desired direction. <IMAGE> |
