ABSTRACT:
The conveyor system (11) is used for transferring rows or large cycles (66) of sheet stacks (12) from the stacking station (20) of a paper converting machine, e.g. a small format cross-cutter to several parallel-running discharge conveyor belts (24, 25). For this purpose grippers or tongs (48) are provided, which are guided on gripper supports (39) and which can draw the stacks (12) from stacking station (20) via conveyor belts (24, 25). For each stacking position (21) there are two grippers (48, 48a), which in each case alternatively grip and transfer a stack, whilst the other gripper performs the return movement and passes into its waiting position upstream of the stacking station.
