The attachment station 11 for the booklets 3 is arranged in the transition region between the infeed conveyor belt 8 and discharge conveyor 11. In FIG. 3 and FIG. 4 It is clear that the inlet belt 8 is arranged higher than the outlet belt 11, ie the transition from the inlet belt 8 to the outlet belt 11 tilts the container la due to gravity on the outlet conveyor belt 11. This tilting is exemplary in FIG. 4 shown. When tilting the bottom 6 of the enclosure 2 is exposed. This position uses the device 1 for Attachment of the booklets 3, so that from the containers 1a, the desired containers 1.

The booklets 3 are stored in the already mentioned booklet magazine 13, already finished bagged in their booklet cover 4. For attaching to the container 1a now a bagged booklet 3 is brought from the aforementioned slide 14 from the booklet magazine 13 and transported via the carriage guide system 15 in the attachment station 10 in the transition region between the inlet belt 8 and outlet belt 11. For example, this may be a pneumatic carriage device. On its journey from the booklet magazine 13 to the attachment station 10, the carriage 14 passes through the bagged booklet 3 with the hot-melt adhesive station 12a already mentioned, in which the side of the booklet cover 4 provided for attachment is sprayed with hot-melt adhesive becomes.

In the attachment station 10, the bagged booklet 3 is raised by the already mentioned pressing devices, precisely at the moment when the container 1a tilts from the infeed conveyor 8 onto the outlet conveyor 11 and the underside 6 of the enclosure 2 is released. By lifting the eingetütete booklet 3 is pressed against the bottom 6 of the wrapper 2, where it sticks due to the hot melt adhesive on the booklet cover 4 and is carried along by the moving container 1a. As a result of the subsequent resting of the underside 6 of the envelope 2 of the container 1 on the outlet conveyor 11, the bagged booklet 3 is pressed flat against the envelope 2 and thus adhesively bonded by the gravity of the container 1 to the envelope 2. A container 1 according to the invention was thus produced from the container 1a without a booklet.

The pressing device, which lifts the bagged booklet 3 in the attachment station 10, can be provided directly in the carriage 14 and moved with it. But it is also an arrangement independent of Carriage 14, for example, firmly integrated into the attachment station 10, possible.
