Abstract: (in conjunction with Figure 6) 1. Process and apparatus for the testing of carton packs. 2.1. Conventionally, large-volume carton packs are con- structed in such a way that two mutually opposite walls (bottom wall 19 and cover wall 20) are formed from folding tabs (15 to 18) overlapping one another. The folding tabs are connected to one another by adhesive bonding. Furthermore, an adhesive strip (51) can be affixed in the region of a parting line (25) between the outer tabs (17, 18) butting against one another. The connection between the folding tabs or the arrangement of the adhe- sive strip (51) may be defective. 2.2. In order to check the carton pack (10) in terms of a correct construction, pressure is exerted on the walls (bottom wall 19 and cover wall 20) formed from folding tabs, in such a way that any inadequate connections re- sult in a springing open of the respective walls. The change in shape of the carton pack (10) is detected by sensors, especially by photosensors (87, 88). 2.3. Any faulty packs are separated out of the feed stream, put in order and reintroduced into the stream.
