Furthermore, the invention also relates to a blank made of cardboard for producing a packaging with this device according to the preamble of claim 5.

Numerous packagings designed in this way are known some of which are laboriously done by hand must be erected.  

From DE-OS 37 40 920 a device is known in of two star wheels and several folding rails are around a U-shaped section of packaging form. This device works relatively fast and reliable, an exact Formation of the U-shaped section is only there difficult to ensure.

The invention has for its object sleeve-shaped Packaging with intermediate bars for in two rows arranged containers on a very quick and easy To be able to produce, in particular an exact Training of the intermediate webs should be possible.

This object is achieved in that above the rails at one with the transport device synchronously running conveyor fixtures attached are, which have drivers, each in one corresponding recess in the upper section of the Intermediate webs and intervene at the same time in the fingers running synchronously with the transport device Press the cloth slightly down, the intermediate webs with shape their walls.

This device enables the packaging to be erected in a single, very efficient operation, one very stable, the containers have an excellent hold providing and dimensionally stable packaging is obtained.

It is very advantageous if a a star wheel provided downstream of a gluing station which is the rag for fixing the intermediate web with an adjacent floor area section compresses.

This star wheel only presses those to be connected Cutting areas together, without the rest, neighboring Expose areas to unnecessary pressure.  

Another very advantageous embodiment of the The device according to the invention is characterized in that that on a chain running above the packaging knife-shaped pressure pieces are provided, which against a web provided in the top surface of the packaging are directed and able to push it down, and that in parallel feeders for the Containers are provided, which the container laterally lead up and with their flange under the footbridge push.

The arrangement of rails, which under the above grab the outer edge flange portions of the container and lifting them has proven to be particularly advantageous especially if parallel to it above the top surface another rail running approximately between the containers is provided which increases the surface area and the Prevents containers, causing the containers to stick to theirs Bottom be tilted apart.

The above-mentioned object is also achieved by cutting from cardboard to produce packaging, which is characterized according to the invention in that in the upper Section of the intermediate web elongated recesses are provided, in which the drivers who are Shaped pieces arranged to form the intermediate web are able to intervene.  

This configuration of the blank will flawless transport without any lateral dodging achieved during the deformation of the intermediate web.

It is very advantageous if the Intermediate web forming floor surface section through across Rag extending in the longitudinal direction of the intermediate web is interrupted, which is punched out of the bottom surface and are formed on one side with a narrow side on this.

These rags stabilize the intermediate bridge very much effective and are particularly easy to install.

It has been found to be particularly advantageous if according to the two long sides of the cloth punctuated cut lines from the floor surface are separated.

The punctiform interruptions of the two cutting lines cause the rags during stacking and of the transport remain in the cutting plane and thus do not cause interference; on the other hand, these are punctiform interruptions of the cutting lines or punctiform webs very easily when pushing out the To separate rags.

In the drawing, the invention is based on a Embodiment of packaging and a device illustrated. Show:

Fig. 4 shows a further section of the device with a star wheel for fixing the intermediate web and

Fig. 5 shows a portion of the device in which clamping fingers are provided.

1 in FIG. 1 denotes a flat cardboard blank which is provided for producing a packaging for four cup-shaped containers arranged in two rows. The cardboard blank 1 has a top surface 2 , on each of which a side wall 5 or 6 is articulated via folding lines 3 and 4 . Within the fold lines 3 and 4 there are cut lines 7 into which the cup-shaped containers can engage with their edge flanges. In the middle of the top surface 2 there are two parallel rows of further incisions 8 , into which the edge flanges of the cup-shaped containers are also able to engage. On each of the two side walls 5 and 6 , a bottom wall section 11 or 12 is articulated via a further folding line 9 or 10 , which are folded over one another when the packaging is erected and closed, section 11 being on the outside and section 12 on the inside is coming.

The inner bottom section 12 has four sections one behind the other, divided by section lines 13 and 14 , from each of which an intermediate web 15 is formed. These intermediate webs 15 are each articulated to the bottom section 12 via fold line sections 16 and 17 and divided into two side sections 20 and an upper section 21 by further fold lines 18 and 19 . The two side sections 20 contain recesses 22 into which the cup-shaped containers can engage with their lower section. The upper section 21 of the intermediate web 15 has an elongated hole-shaped recess 23 , into which a driver engages when the packaging is erected.

Between each two adjacent intermediate webs 15 - separated by the cutting lines 13 and 14 - a tab 24 is arranged, which is somewhat shorter than the flat intermediate web 15 and is therefore formed on only one side on the bottom section 12 . The two cutting lines 13 and 14 are interrupted by punctiform bridges 26 and 27 , which ensure that the tabs only emerge from the plane of the bottom section 12 when these bridges are severed. When the intermediate webs 15 are erected, the two side sections 20 are folded upward and the free end of the tabs 24 is glued to the opposite edge of the base section 12 , so that the intermediate webs are fixed.

In Fig. 2, a fully erected, equipped with cup-shaped containers 25 and sealed package is shown.

Using the other figures, the method for Erecting this packaging will be explained.

In Fig. 3, two guide rails 30 are shown on which the cardboard blank 1 is transported via not shown carriers. Above these rails 30 , a plurality of shaped pieces 32 are attached to a transport chain 31 , the outer shape of which corresponds to the inner shape of the intermediate webs 15 to be formed. These fittings are moved down against the two rails 30 and press the sections 20 and 21 of the intermediate web down, whereby this intermediate web is formed. On the underside of the shaped pieces 32 there is a mandrel 33 which engages in the cutout 23 in the blank and also pulls the blank 1 along so that it cannot warp during the deformation. The tab 24 is at the same time slightly pushed out of the plane of the bottom section 12 , so that its free end and the opposite section of the bottom section can slide over one another. Before sliding over one another, an adhesive is applied in this area and then the two superimposed material sections are pressed together by means of a star wheel 40 shown in FIG. 4.

The cup-shaped containers 25 are now moved against the underside of the blank 1 , which is still lying flat in the remaining areas, from both sides. At the same time, the web 42 lying between the incisions 8 in the top surface 2 is pressed down by knife-shaped pressure pieces fastened to a circumferential chain, not shown, so that the edge flanges of the containers can engage in the incisions 8 and then with a section on the top of the respective web 42 rest. When the two side walls 5 and 6 are subsequently folded down by folding rails (not shown), opposite sections of the edge flanges engage in the cutting lines 7, as a result of which the edge flanges are already very well anchored to the top surface 2 . Thereupon, the two rows of containers are slightly tilted apart by rails engaging on the projecting edge flange sections, further rails holding the central section of the top surface 2 and the containers in this central region and preventing their rising. As a result, the gap between the containers is somewhat enlarged, so that the intermediate web 15 formed on the base section 12 can easily penetrate between the containers; a folding ruler, not shown, is again provided for this. To tension the two bottom sections 11 and 12 and thus to achieve a tight fit of the packaging on the containers 25 , clamping fingers 50 are provided, which are fastened to two circumferential chains 51 and engage in openings 53 and 54 , respectively, which then adjoin the two folding lines 9 and 10 are provided in the two bottom sections 11 and 12 . During this tensioning process, the two bottom sections 11 and 12 are then glued together.
