  • Patent number: 6383123
    Abstract: An apparatus for transferring and erecting folded boxes between a dispensing station and a receiving station of a cardboard box making machine. The apparatus includes a plurality of suction systems with suction heads. The suction heads, which each rotate about a common pivot axis, are each coupled to a separate drive mechanism. The device mechanism varies an angular speed of rotation of the respective suction head on a revolution about the pivot axis, so as to adapt this speed to a particular function required at that time. The apparatus has a high output and makes easy adaptation to various folded boxes possible while simultaneously achieving high functional safety and reliability.
