As indicated in FIG. 13, the suction cups 52 are connected to a vacuum source (not shown) via a channel system 54. The same applies to the suction funnels 53. Alternatively, the two suction cups 52 can perform both functions.
• the multifunction hand 17 of the robot 16 works in detail as follows: To pick up paper strips or paper intermediate layers 33, the multifunction hand 17 is brought into the appropriate position by means of the robot control so that a paper intermediate layer is removed from the paper magazine after suction air has been applied in the suction funnels 53 can. The paper intermediate layer is then placed on the wire bracket 23 held in the correct position. For this purpose, the suction funnels 53 are briefly acted upon by blown air. A stack of bags is then removed from the pin stack conveyor 4 and suspended on the wire brackets held in alignment in the fixing and functional unit 24. Then another paper strip or paper intermediate layer 33 is picked up again by means of the robot or the multifunction hand and placed on the wire bracket 23.
